 Attention

Installing the Clamp-on Ferrite

One ferrite has been included with your X-12 installation kit to help suppress undesired
electromagnetic interference. Rather than install it at the factory, this ferrite has been pack-
aged separately so that you can attach it after the cable has been run, thus easing installation.

Place the ferrite on the console end of the cable that connects the X-12 console to the power
supply.

To attach the ferrite:

1. Place the ferrite on the cable so that the ferrite's curved inner edge rests
firmly on the cable, close to the connector that plugs to the console power
connector.

2. Press the two halves of the ferrite closed until they snap together.

3. Place the split washers (2) on the cable on the each side of the ferrite.

4. Attach the cable ties (2) just below the washers so that the ferrite cannot slide
down the cable.

Refer to the following figure.

X-12 Audio Levels
General
All professional digital audio broadcast consoles manufactured by Audioarts are hybrid in
nature. That is, they allow the user to connect both analog and digital domain sources and
provide both analog and digital outputs. While this approach allows for greater flexibility when
interconnecting source and destination equipment, the user must be aware of what levels to
expect when applying, say, a digital input and measuring at an analog output.

Gain Structure
Broadcast consoles by design have various electronic stages at which the signal level may
be amplified or attenuated. The primary stages are the A-D converter input, channel fader,
DSP mixing, and the bus output D-A converters. The sum of these gain stages is commonly
referred to as the console’s “gain structure.” Wheatstone consoles are factory calibrated for
0dB or “unity gain” when the input channel fader is set to nominal (-12dB).

The following is a stage by stage breakdown of the X-12 console’s gain stages:

Analog Input (A-D Converter)

• The ADC input circuit cards are designed so that a +4dBu input signal will yield
a -20dBFS digital output with the channel fader at nominal.
• An input gain adjust switch setting can be changed to increase the gain by 8dB to
allow for interfacing unbalanced equipment.
• Mic level preamps have trim pots for matching various microphone source levels
to the console’s normal +4dBu analog operating level.

DSP Gain

• Set in firmware for unity gain (-20dBFS input yields a -20dBFS output when the
input channel fader is set to nominal), digital attenuation may be applied on a
channel by channel basis via a dipswitch setting.

Analog Bus Output Gain (D-A Converter)

• The analog output DAC circuits are designed so that a -20dBFS digital input signal
will yield a +4dBu analog output with the channel fader at nominal.

 Important

Audio Reference Levels

All consoles are fully factory calibrated and will comply with the following reference level:

-20dBFS digital = +4dBu analog = 0VU Note: 0dBu = .775v rms

+4dBu = 1.23v rms

These settings will provide a headroom of 20dB over the nominal input signal of +4dBu
analog, or -20dBFS digital.

Note that due to the lack of level standards in the digital domain, headroom available for
digital sources will be entirely dependant on the source. In fact, CD's are frequently made
with less than 1dB of digital headroom, and any boosting of digital CD levels in the console
by moving the fader up above the nominal can result in overload distortion for that channel.
For this reason, a dipswitch allows for digital attenuation on a fader by fader basis; digital
sources can be conveniently attenuated this way to guard against digital overload caused by
not enough headroom on the digital source. Since the X-12 console meters are true digital
reading meters, they will always show the console's digital levels, and whether there are any
"overs" in the signal. By pressing a channel's "CUE" button, the switched meters will show
the digital level of that channel's source. By using the program and watching these meters, the
amount of attenuation can be adjusted to meet your headroom requirements.

Typical Input Levels

Mic Inputs Nominal = -50dBm, 150ohm Maximum = -26dBm

Analog Inputs Nominal = +4dBu Maximum = +24dBu

Digital Inputs Nominal = -20dBFS Maximum = 0dBFS

System Ground
The first step is to ground the console.
Note that as supplied from the factory, console rackmount power supply
common, audio ground, and the X-12 mainframe are connected together
at the console, but are NOT connected to electrical ground and the chassis
of the power supply. Safety requirements dictate that a positive connection
from the console mainframe to electrical ground be made in the completed
installation. Use the grounding lug on the rear of the mainframe to establish
your system ground. The grounding lug may be found at the rear of the
console, on the rear frame panel, to the left if you are looking at the rear
of the console.
The system ground serves two important purposes:
(1) It provides a zero signal reference point for the entire audio system;
(2) It assures safety from electrical shock.
There exist two terms that one encounters in a discussion of ground:
(A) EARTH GROUND, which is usually a heavy copper rod driven into the soil
adjacent to the building (around 6 feet down) or a connection to the copper water
pipes leading into the building. Either is acceptable (unless, of course, the water
pipe is made of plastic).

(B) THE POWER COMPANY EARTH CONDUCTOR that enters the building at the
power line breaker box; this conductor should be (and is often by code) tied to the above-
mentioned earth ground at one point. This point is the SYSTEM EARTH GROUND.
TIE THE CONSOLE GROUND LUG TO THE SYSTEM EARTH
GROUND. TIE EVERY PIECE OF EQUIPMENT IN THE ENTIRE AUDIO
SYSTEM TO THE CONSOLE GROUND LUG. If the system earth ground
point is inaccessible, tie the console ground lug to the power company earth
conductor at the main breaker box (see drawing “Typical Grounding Scheme”
on previous page).
Each piece of equipment should be connected by its own ground wire (usu-
ally the round third pin on the AC cord). This means that every AC outlet must
have a separate conductor run to the console ground lug; the outlets cannot be
daisy-chained as is normally encountered in commercial and residential AC
systems. Any equipment not supplied with 3-wire AC cables must have indi-
vidual ground wires (16 gauge or larger) connected to their chassis grounds
and then run to the console ground lug terminal strip.
Further Grounding Details
Check all equipment to be absolutely certain that each unit is power trans-
former isolated from the AC mains to prevent safety hazards.
It is assumed that in each piece of audio equipment the audio ground and
the chassis are tied together at some point. Any piece of equipment lacking a
grounded chassis is likely to be prone to interference problems.
Locate all unbalanced audio equipment in the same rack if possible, to mini-
mize chassis ground potential differences. It may also be helpful to insulate each
piece of unbalanced equipment from its mounting rails in the rack by means
of nylon 10-32 screws and insulating washers between rails and faceplates.

Once the system is properly grounded, proceed with the console power
supply installation and connection (next section).

Power Supply

Front view of the SPS-100 rack-

Rear view of the SPS-100 rack-

The X-12 console is powered by an Audioarts Model SPS-100

rackmount power supply. This unit occupies two 19” wide rack spaces
(total height 3-1/2”). Convection cooled, it requires ample ventilation
space above and below it. The SPS-100 generates heat in the course of
normal operation — do not mount heat sensitive devices in the same
rack cabinet.
Note the power supply should be
mounted in an equipment rack within
fifteen feet of the console (but no closer
than 3 feet). Avoid locating any high gain
equipment (such as phono preamps, tape
recorders, etc.) too near the rackmount
supplies, to avoid magnetic interference
into that equipment.

other non-audio machinery. The third pin ground wire of the AC source
should be tied to the central system ground point.
Energizing
Assuming the X-12 console mainframe is properly placed and grounded,
and its SPS-100 power supply correctly rackmounted and connected to
the console, you may now energize the power supply by plugging it into
the AC mains.
Note: To de-energize the console, unplug the rackmount power supply’s
AC cord from the AC mains. Never de-energize the console by discon-
necting the cable that connects the console and power supply together.

Once you have verified proper power-up, unplug the rackmount power sup-
ply to de-energize the console. You may now proceed to wire up audio and
control connections.

Audio and Control Wiring

Audio I/O and control connections to the X-12 console are made
via RJ-45 connectors, and 6-pin and 3-pin plug terminals, located
on the rear panel of the console. See the console’s rear drawing on
page 1-8.
Digital Audio Connections
CABLE - All AES/EBU input and output digital audio connections
are balanced and should be made using a high quality digital audio cable.
Be sure to select a digital audio cable with an integral drain wire of the
same wire gauge (AWG) as the twisted pair. Typical AES/EBU digital
audio cable has a very low characteristic capacitance per ft (pF/ft), and
a nominal impedance of 110ohm. High quality digital audio cable offers
better signal transmission performance versus typical analog audio cable,
especially over long cable runs. Check the cable manufacturer’s data sheet
to be sure the cable you plan to use will work in your application.
CONNECTORS - All AES/EBU connections are made with the sup-
plied RJ-45 connectors.
SPDIF INPUTS - The SPDIF (Sony/Phillips Digital Interface) or “con-
sumer” digital audio interface is a two wire unbalanced signal typically
on a single RCA style connector. We recommend using shielded twisted
pair cables for these connections. Wire the SPDIF center conductor (HOT)
to the SRC-X12 “HI” input pin using one wire of the pair and wire the
SPDIF shell (ground) to the SRC-X12 “LO” input pin with the other wire
of the pair. Connect the cable’s shield to the SRC-X12 “SH” pin, leaving
the shield floating (that is, not connected) at the SPDIF end.
X-12 / May 2011 page 1 – 6
 I N S TA L L AT I O N A N D P O W E R

The SRC-X12 digital input audio card is provided with 110 ohm / 75 ohm
switches on the A and B inputs to allow impedance matching with 75 ohm sources.
Unbalanced Connections (analog audio)
ANALOG INPUTS — Wire to the console with typical shielded two conduc-
tor cable (like Belden 9451), just as if you were connecting a balanced source.
At the unbalanced source machine’s output, connect the black wire (LO) to the
shield.
ANALOG OUTPUTS — All of the X-12 console’s line level analog outputs
are electronically balanced, low impedance, outputs, expecting a minimum load
of 600 ohms. The outputs are balanced but are not floating, and therefore should
only be connected to external equipment having balances inputs.

Hook-Ups
The rear of the console has six slots for plugging in the analog (ADC‑X12) or
digital (SRC-X12) input daughter cards. Each daughter card provides the audio input
circuitry for two faders. The rear of the console also has a plug‑in dual microphone
preamp card (MP-X12) with a 6-pin plug terminal provided for microphone MIC 1
and MIC 2 inputs, and the two RJ-45 connectors for microphone preamp outputs.
Additional RJ-45 connectors are provided for monitor, analog, and digital program
outputs, caller input/output, external input, USB port, and logic connections. There also
is a 3-pin plug terminal provided for tally connections, and a USB port with type B
connector for interfacing with a computer (see page 2-6 for details).
Pinout drawings on pages 1-13 through 1-16 show all wiring connections at glance.

Logic Port Mapping

The X-12 console has six logic “ports” for interconnection to remote machines or
control panels. These logic ports are assignable to the input fader channels 1-12 and
the phone channel via dipswitch assignments (covered in greater detail on page 2-8).
For now, suffice it to say that logic port numbers in the following discussion refer to
the logic port that the fader channel is mapped to.

To Turn the Channel ON and OFF from a Remote Location

“Remote location” can also refer to a remote source machine that is feeding
its audio to the channel in question. A contact closure (which may be sourced
by the external machine) will activate the channel’s ON switches.
REMOTE ON — Activates the channel’s ON switch. Momentarily con-
nect Remote On (Pin 7) and Digital Ground (Pin 1) to latch the channel ON.
(User-supplied momentary contact switch required.)
REMOTE OFF — Activates the channel’s OFF switch. Momentarily con-
nect Remote Off (Pin 6) and Digital Ground (Pin 1) to latch the channel OFF.
(User-supplied momentary contact switch required.)

To START Remote Source Machines Using Channel ON Switch

EXTERNAL START — Hook up the remote machine’s “start” control pins
to the channel’s RJ-45 connector control pins: wire to Pins 4 and 2.
Talkback to Control Room
In order for talent in the studio to talk to the console operator, the input
channel controlling the studio’s microphone signal must be routed to the con-
sole’s cue bus, where it can be heard by the operator. This is accomplished by
a user-supplied TB switch wired to provide a momentary closure between the
logic port RJ-45 connector “TB to CR” (Pin 3) and Digital Ground (Pin 1).
As long as this closure is maintained (i.e., as long as talent holds down the
TB button) the channels’s pre-fader, pre-on/off signal will be placed on the
console’s Cue bus.
On Tally
Lets the channel’s ON switch control an on-air light or other “microphone
on” indicator at a remote location. This control function provides a continu- NOTE: In most cases,

This closure can be used to control an externally powered tally light that instead of an On Tally
requires a continuous closure to function. Or an external tally light (i.e., LED) output from one of the

can be powered from the logic ports by connecting the external LED to +5V
Digital (Pin 8) and the On Tally connection. In either case the current should
not exceed 30 milliamps.

Input Daughter Card Installation

To configure the console inputs, two types of daughter cards are available (Figure 1):

Figure 1. Input Daughter Cards

• Analog ADC-X12 (W#002824) daughter card;

• Digital SRC-X12 (W#002826) daughter card.
Each daughter card determines the input signal type, analog or digital, for two ad-
jacent audio channels. One card configures channels 1 and 2, the next card configures
channels 3 and 4, etc.
The daughter cards specific to your order are shipped in a separate package.
• The ADC-X12 analog daughter card is configured at the factory to work with +4dBu
balanced sources, but can be configured for 8dB of additional gain for situations
where lower level line sources are used with the 4 position dipswitch SW1. When
a dipswitch position is on the associated audio channel is set for normal gain; to
achieve higher gain turn the appropriate dipswitch off.

SW1 position 1 controls the left side gain of the second (even) channel
SW1 position 2 controls the right side gain of the second (even) channel
SW1 position 3 controls the left side gain of the first (odd) channel
SW1 position 4 controls the right side gain of the first (odd) channel

Please note that the gain switches affect both A and B inputs (see page 3-3) of the
channel, so it is best not to have a +4dBu source on an A input and a lower level source
on the same channel’s B input.

To install the console’s daughter cards you must follow this procedure:
• Make sure the console is powered down.
• Slide the daughter card in the appropriate opening in the rear of the console to
plug in its edgecard fingers to the motherboard edge connector. (Figures 2 & 3).

Console Features
Overview
Each X-12 console has two Input panels and one Master panel. The Input panel
consists of six faders with associated switches. The Master panel has a CALLER,
MONITOR and METERS sections. Each section is described below.
The basic purpose of the console is to take some of the many audio signals that are
wired to the console inputs, and generate several outputs that combine these inputs in
various groups and at various degrees of loudness, or signal strength. The typical ap-
plication is in a radio station where it is desired to develop the signals that the station
will broadcast (the on air signal), as well as several additional signals for recording
and monitoring.

OLLEE FFEEAATTUURREESS

Mic Preamp

The X-12 console is provided with one dual channel microphone (mic) pre-
amp card, designed to bring balanced microphone level signals (nominally
-50dBu) up to a +4dBu balanced line level for routing into any fader channel provided
with an analog daughter card. For the uninitiated, mic preamps are required because
microphones typically put out signals at relatively low signal strength, and therefore
require more amplification (increase in signal strength) than normal line level sources,
like CD players and tape players, to be properly audible at the console’s outputs.
It is important to note that the end user or installer must deliberately wire the mic
preamp outputs to the desired analog input fader channels, as there is no internal
path provided to make this connection.
Mic level sources are wired to the 6-position plug terminal that is plugged into the
mating 6-position MIC IN 1 and 2 connector on the mic preamp at the rear of the con-
sole. The line level mic preamp outputs are available at the two RJ-45 MIC OUT 1 and
2 connectors on the mic preamp, which must then be wired to the appropriate analog
inputs via the analog input RJ-45 connectors.
M 1 and M 2 GAIN trimpots, also on the mic preamp at the rear of the console, are
used to adjust the gain of each microphone input independently. These are normally
“set and forget” adjustments, and are set at the factory for a gain of 54dB, thus bringing
a -50dBu microphone input level up to +4dBu at the output.
Example: with a microphone input of –60dBm @150 ohm at the port, gain trim can set levels from
-22dBu to +16dBu (note maximum preamp gain is +76dB) at the PGM 1, PGM 2, or PGM 3 output.
If you have more than two microphones in use, you will need to provide external
mic preamps for all but two of them.

Line Level Inputs

The X-12 console has provision on
the rear panel for mounting six dual chan-
nel audio daughter cards to provide the
console’s twelve fader channel line level
inputs. Each daughter card, which may be
either an analog input card or a digital input
card, handles the line level input signals
for two fader channels. Looking at the
rear of the console, from right to left the
X-12 / May 2011 page 2 – 4
 CCO
ONNSSO
OLLEE FFEEAATTUURREESS

daughter cards feed faders 1 and 2, faders 3 and 4, faders 5 and 6, faders 7 and
8, faders 9 and 10, and faders 11 and 12, respectively. Daughter cards are either
analog or digital for both fader channels. Thus, if fader 1 is analog, fader 2 must
be analog as well, or if fader 1 is digital, then fader 2 must be digital also. The
same rule applies to each mentioned pair of faders.
Each fader channel is capable of A/B operation. This means that each daugh-
ter card provides inputs for four stereo signals: first fader A input, first fader B
input, second fader A input, and second fader B input. To overstate the obvious,
each analog card then has four analog stereo inputs, and each digital card then
has four digital inputs; there is no mixing of analog and digital inputs on a single
daughter card.
The X-12 also has one external stereo line level (+4dBu balanced) input that is
available for control room, studio, or switched meter monitoring, and one analog
(+4dBu balanced) input dedicated to use as a telephone caller input.

Outputs

The outputs for all three of the X-12’s main stereo buses, PGM 1, PGM 2,
and PGM 3, are available as both analog and digital outputs. Both analog and
digital outputs from a bus may be used at the same time.
The analog bus outputs all appear on the group of four RJ-45 connectors
mounted below the FADER 11-12 connectors on the rear panel. This group of
four connectors also includes the CALLER I/O connector with the dedicated
caller output (+4dBu analog balanced) and the previously mentioned dedicated
caller input.
The digital bus outputs all appear on the group of four RJ-45 connectors
mounted below the FADER 9-10 connectors on the rear panel. This group of four
connectors also includes the EXT IN L/R connector with the previously mentioned
external monitoring input, which accept a +4dBu line level stereo analog input.
An additional group of four RJ-45
connectors mounted below the MIC card,
provides stereo analog line level (+4dBu)
balanced outputs for Control Room, Stu-
dio, Cue, and Headphones. In addition to
appearing at this connector, a mono sum of
Cue feeds the internal cue speaker, and the
Headphones signal also feeds the console’s headphone jack.

USB Port
The console contains a USB
2.0 interface, available via the
USB Type B connector on the
rear panel, to enable audio to pass
between the console and a USB
port on a computer. Internally,
dipswitches select from PGM 1,
PGM 2, or PGM 3 as the audio from the console to the computer (see “Console In-
ternal Programming”). Audio coming back from the computer via USB shows up as
a stereo digital signal on the USB OUT RJ-45 connector. From there, the audio can
be patched to any digital line input.

Using the USB Port . . .

Any computer having a USB port and installed drivers capable of passing and
utilizing digital audio data should work with the X-12 USB port. Use a cable having
a USB Type B connector on the X-12 end and a connector on the other end that will
mate with the computer’s USB port; this will typically be a USB Type A connector.

. . . With a MAC
In general, this will be a plug-and-play process. The main concern is to choose
the USB Audio Codec under System Preferences>Sound as desired for audio input
and/or output. Then simply start the application.

. . . With a Windows® PC
When you first connect the X-12 USB port to a PC running Windows you will see
the famous “found new hardware” sequence of messages. At some point this sequence
should end with a message that the new hardware is installed and ready to use.
Setting up any given application to use the X-12 USB port will depend on the ap-
plication itself. Generally, you will need to select the appropriate device from a list
of devices in a Preferences dialog.
As an example, let’s look at WinAmp, a free software application used by mil-
lions to play back audio streams from a network (or the Internet), or to play audio
streams into a network.
To play audio from the X-12 on the computer:
• Install the free LineIn plugin for WinAmp.
• Under Preferences - Input select the LineIn plugin from the Input list and click
Configure, then find the USB Audio Codec in the list of available devices and
note its corresponding device number, which you will need below.
• In WinAmp, choose Play URL...
• Enter “line://dev=n” where ‘n’ is the device value that you discovered above.

Other Computers
If your computer does not use one of the above operating systems, or otherwise
behaves differently than described above, consult the documentation for that computer,
operating system, and/or application.

General Considerations
If any problems are encountered, please consider the following points:
• The audio that is output from the X-12 on the USB port depends on the setting
of the internal dipswitches that select between PGM 1, PGM 2, and PGM 3 as
the source (see “Console Internal Programming”).
• The audio coming back into the X-12 on the USB port is available at the USB OUT,
which must be patched to a digital line input if you want it to come up on a fader,
or to some external device if that’s where you want it to show up.
• If you are not able to get the audio into or out of the USB port, check the USB
cable, its connections at both ends, and the port selection settings in the applica-
tion you are using.
• If you have the audio flowing where you want and it suddenly becomes intermit-
tent or disappears, check the USB cable and the connections at both ends.
• Once you have the USB audio under control it is a good idea to make a record
of the application being used, including its version number, the audio direction
(into or out of the computer), and all the settings that were required to make it
work. This information will be invaluable if you later have to troubleshoot the
USB audio, or set it up on another computer.

Mute and Tally

The console has the ability to mute the control room output. The console
also has an on air tally output that is used to drive user-provided external
circuitry. This tally is automatically activated whenever the control room
mute is activated. Thus, turning on any channel that activates the control
room mute also turns on the on air tally.
See the “Console Programming Options” section for details.

X-12 / May 2011 page 2 – 7

OLLEE FFEEAATTUURREESS

Console Programming Options

Most programming is made via PCB mounted dipswitches located at the top of the
console’s rear panel. There are twelve fader dipswitches (FADER 1 - FADER 12), one
caller dipswitch (CALLER), and two monitor dipswitches (MONITOR 1 and MONI-
TOR 2). Note that when a dipswitch position is in the down position it is ON.

FADER 1-12 Dipswitches

Each input channel has a dedicated dipswitch
to program the channel’s audio and logic functions.

Attenuation
As mentioned in the Read Me! pages at the front
of the manual, there is a tendency today for CD’s
to be made with less than 1dB of headroom. Any
boosting of level resulting from moving the fader
up from the nominal, unity gain, position results
in overload distortion. For this reason, dipswitch
position 7 is provided to attenuate a channel’s signal by 12dB, thus allowing channels
being fed by such hot CD’s to have their faders moved above nominal without causing
distortion. The 12dB attenuation is applied to the three main stereo buses, cue, and talk-
back — in other words, anywhere in the console that the channel’s audio may be routed.
FADER 1-12 dipswitch position 7 applies 12dB of attenuation to the channel for all
bus feeds

PGM 3 Bus Pre-Fader

Position 8 of the FADER 1-12 dipswitches, when activated, will cause the channel
signal assigned to the console’s PGM 3 output to be tapped before the fader. One possible
use for this feature is to allow the board operator’s mic to be heard by the caller, using
PGM 3 as the caller feed, without the board operator’s mic fader needing to be moved up.

CR Mute
An input channel can be programmed to mute the control room speakers when the
channel is ON. Position 9 of the FADER 1-12 dipswitches, when activated, automatically
mutes the console’s control room speakers when the corresponding channel is turned
ON. This is done to prevent feedback from any live mics in the Control Room.

X-12 / May 2011 page 2 – 8

 CCO
ONNSSO
OLLEE FFEEAATTUURREESS

Logic Assign
The X-12 console has six logic ports. Positions 1 through 6 of the FADER 1-12
dipswitches, when activated, assign the corresponding logic port to the input channel:
Dipswitch pos.1 assigns the logic port 6
Dipswitch pos.2 assigns the logic port 5
Dipswitch pos.3 assigns the logic port 4
Dipswitch pos.4 assigns the logic port 3
Dipswitch pos.5 assigns the logic port 2
Dipswitch pos.6 assigns the logic port 1

A Note On Logic Port Assignments

Because of the way logic ports are assigned to input channels, it is entirely pos-
sible to assign a logic port to more than one input, or to assign multiple logic ports
to a single input, or even to combine these two cases, to the extreme end of having
all six logic ports simultaneously assigned to every fader. However, don’t do it! The
results will be unpredictable at best.
The main reason we mention this is because it can happen, and, if you are expe-
riencing erratic or unpredictable logic interfacing between the console and remote
equipment, the very first thing you should do is to verify that you do not have multiple
logic ports assigned to the same fader, and that you do not have any logic ports
assigned to multiple faders simultaneously. Such configuration is unsupported.

CALLER Dipswitch

Cue Dropout
CUE (i.e., caller COM button) can be made to turn
off when the channel’s ON switch is pressed. This is the
factory default setting.
CALLER Dipswitch position 7 activates cue dropout

Cue Pre/Post
The channel’s CUE signal (caller COM button) can
tap pre or post fader.
CALLER Dipswitch position 8 activates post-fader
cue (default is pre)

CR Mutes
A caller channel can be programmed to mute the control room speakers when the
channel is ON. Position 9 of the CALLER dipswitch, when activated, automatically
mutes the console’s control room speakers when the caller channel is turned ON.
This is done to prevent feedback from the CR announcer’s mic, through the external
phone path.

X-12 / May 2011 page 2 – 9

 CCO
ONNSSO
OLLEE FFEEAATTUURREESS

Logic Assign
Positions 1 through 6 of the CALLER dipswitch, when activated, assign the
logic to the caller channel:
Dipswitch pos.1 assigns the logic channel 6
Dipswitch pos.2 assigns the logic channel 5
Dipswitch pos.3 assigns the logic channel 4
Dipswitch pos.4 assigns the logic channel 3
Dipswitch pos.5 assigns the logic channel 2
Dipswitch pos.6 assigns the logic channel 1

Gain Trimpot
There is a PCB-mounted CALLER trimpot, located on the middle of the con-
sole’s rear, that sets caller input gain.

MONITOR 1 Dipswitch

Split Cue, Control Room

The MONITOR 1 dipswitch pos. 1, when
activated, allows a summed (L+R) version
of the regular program to be sent to the right
side of the CR monitor stereo output, while a
summed version of CUE is sent to the left side.
The CUE TO CR dipswitch (MONITOR 1
position 2) must be activated to achieve Split
Cue (see below).

Cue Interrupt
The MONITOR 1 dipswitch pos. 2, when activated, sends cue to the control
room.

Cue Mute
The audio from both the control room speakers and the console’s built-in meter-
bridge cue speaker can easily be picked up by the console operator’s microphone.
This is a potential source of feedback. For this reason the console provides muting
to the control room output and, optionally, the built-in cue speaker, whenever a mic
programmed for control room mute is turned ON with A selected as the input source.
MONITOR 1 dipswitch pos. 3 will mute cue whenever the CR output is muted
by an input channel set to activate the CR mute

Phantom Power
MONITOR 1 dipswitch pos. 7 and 8 turn phantom power on for the two mi-
crophone input ports.
Dipswitch pos. 7 activates phantom power for microphone 1
Dipswitch pos. 8 activates phantom power for microphone 2

EFS - European Fader Start

In some situations it is desirable to have the channel’s on/off status controlled
by the position of the fader. In such a scenario, if the fader is all the way down and
the channel is off, moving the fader up slightly from the full down position will turn
the channel on without the need to press the channel ON button. In a similar man-
ner, if the fader is up from the full down position by at least a small amount and the
channel is on, moving the fader to the full down position will turn the channel off
without the need to press the channel OFF button. This feature is enabled by moving
the dipswitch position 9 down (on).
The MONITOR 1 dipswitch pos. 9 enables the EFS feature
Please note that this is a global setting. EFS is either enabled for all 12 input
faders or disabled for all 12 input faders. You cannot enable or disable the feature
separately on individual faders.

MONITOR 2 Dipswitch

Split Cue, Headphone

Consoles are normally programmed at the factory
for the L+R sum of CUE to appear on the left chan-
nel, while the L+R sum of the control room output
appears on the right. To defeat this split cue option,
move up (off) pos.1 of the MONITOR 2 dipswitch.
Then cue will interrupt both sides of the headphones.

Talkback to Studio
The X-12 console has an internal talkback (TB) bus that allows audio from any
of the faders 1-4 to be used by the console operator to talk to talent in the studio.
Typically, one of these faders would be used, but, to accommodate those situations
where more than one microphone is used for the talkback function, any of the first
four input channels may be assigned to feed the talkback bus. Positions 6-9 of the
MONITOR 2 dipswitch are used for this purpose. Turning the switch on routes that
channel’s pre-fader, pre-on/off signal to the talkback bus. When the console opera-
tor presses the TB switch on the MASTER panel, the talkback bus audio interrupts
the feed to the studio speakers, allowing the console operator to talk to studio talent.
Dipswitch pos. 6 allows input channel 4’s audio to feed the talkback bus
Dipswitch pos. 7 allows input channel 3’s audio to feed the talkback bus
Dipswitch pos. 8 allows input channel 2’s audio to feed the talkback bus
Dipswitch pos. 9 allows input channel 1’s audio to feed the talkback bus

Console Sample Rate

The X-12 console is set at the factory to operate at a sample rate of 44.1 KHz.
Slide switch SW 4 on the motherboard is provided to change the sample rate to
48 KHz if desired.
Power down the console and remove the screws that hold in the first IP-X12 Input
Panel. Carefully raise the front end of the panel, nearest the armrest, taking care not
to strain or disconnect the ribbon cable that connects the panel to the motherboard.
Standing at the console operator position and looking under the panel at the
motherboard, you will find switch SW 4 just to the right of the connector that the
panel’s ribbon cable plugs into. Slide this switch to the right for a sample rate of
48 KHz, or to the left for 44.1 KHz.
With the switch set at the desired position, carefully lower the panel back down
and replace the screws that hold down the panel. You can now power the console
back up.

Selecting USB Feed From Console To Computer

The X-12 console is set at the factory to have the PGM 2 bus feed the USB
output to the external computer. Dipswitch SW 2 on the motherboard is provided
to select this feed.

SW 2 position 1 selects PGM 1 as USB feed

SW 2 position 2 selects PGM 2 as USB feed
SW 2 position 3 selects PGM 3 as USB feed

Power down the console and remove the screws that hold in the first IP-X12 Input
Panel. Carefully raise the front end of the panel, nearest the armrest, taking care not
to strain or disconnect the ribbon cable that connects the panel to the motherboard.
Standing at the console operator position and looking under the panel at the
motherboard, you will find dipswitch SW 2 at the right, partly under the second
IP‑X12 Input Panel. Slide the appropriate position’s handle to the left (ON) to as-
sign that bus to the USB feed,and make sure the handles for the other two busses
are slid to the right (OFF). NOTE: Only ONE bus may be assigned to the USB
feed — DO NOT have more than one bus feed position turned on.
With the switch set at the desired position, carefully lower the panel back down
and replace the screws that hold down the panel. You can now power the console
back up.

Controls and Functions

Input Panel (IP-X12)
The Input panel of the X-12 console has six identical strips representing
six input channels.

Source Select
Each input channel accepts two analog or digital stereo sources: A and
B, switched at the top of the panel. The INPUT button will be lit when
source B is selected.

Program Assign
Output switches assign the selected source signal to any combination
of the console’s three stereo Program outputs—PGM 1, PGM 2, and PGM
3. The button will be lit when the source is assigned to its respective bus.
To remove a source from the bus, press the button again; the light will go
off to indicate that the source is no longer assigned to that bus. NOTE that
when the console is powered up all input channels will be off, with source
A selected, and assigned to PGM 1.

Cue Button
The CUE switch places the channel’s signal on the console’s cue bus,
where it may be heard on the meterbridge mounted cue speaker, as an in-
terrupt to the console operator’s headphones, as an interrupt to the control
room monitor speakers, if so programmed, and at the console’s CUE output
on the rear panel.
Press the CUE button. The channel’s input signal will be included in
the console’s CUE output at a level that is independent of the FADER set-
ting, and the button will light. The fader does not need to be turned ON. To
remove a fader from cue, press the CUE BUTTON again; the light will go
off to indicate the channel is no longer assigned to cue.

Fader
Level is set by a long-throw fader. The fader is the sliding mechanism
that determines how strong is the presence of the input in some of the vari-
ous console outputs.
If the fader is all the way down (that is, pulled toward the console opera-
tor), the signal will not be present in any of the three program main buses
to which it is assigned. As the fader is moved up (that is, pushed away from
the console operator) the signal will appear more strongly in each of the
main buses to which it is assigned.
The channel’s fader setting will not affect the level of the signal in
CUE. It will also not affect the level of the signal in PGM 3 if the fader has
programmed for PGM 3 pre assignment.

ON/OFF Switches
The ON (red) and OFF (white) buttons on the bottom of the panel turn
the channel on and off by means of electronic switching, and can simulta-
neously start external source machines. These can also be programmed (as
mentioned in the previous chapter) to activate control room mute and cue
dropout. ºExternal machine interfacing is only available on faders that have
been assigned to a logic port.

Caller Input
The caller section is used for telephone call-in talk segments, and con-
trols the audio for the caller. The caller signal enters the console from your
station hybrid.
The caller feed can be any of the three Program buses. The caller feed
setting is displayed by the three program LEDs under the CALLER FEED
button. The caller feed will never contain the caller’s own voice.

Program Assign
Output switches assign the caller to any combination of the console’s
three Program outputs (PGM 1, PGM 2, and PGM 3), and permit live
talk-ins.
Pressing any of the three program switches causes the caller’s audio
to be included in the output mix for that bus, at a level dependent on the
FADER setting, as long as the caller section is ON. The button will be lit
when the caller is assigned to its respective bus. To remove the caller from
a bus to which it is currently assigned, press the button again; the light will
go off to indicate that the caller is no longer assigned to that bus.

COM Button
The COM (SET UP, or Cue) button allows interviewing the caller prior
to airing by including the caller in the console’s cue bus, where it may be
heard on the meterbridge mounted cue speaker. At the same time, the con-
sole’s talkback bus is routed to the output back to the caller, allowing the
operator’s mic (if so programmed) to be used to talk to the caller off line.

Fader
The long-throw fader sets the caller’s signal level.
If a fader is all the way down the caller’s voice will not be present in
any of the three Program buses (PGM 1, PGM 2, and PGM 3) to which the
phone is assigned. As the fader is moved up the signal will appear more
strongly in each of the main buses to which the phone is assigned.
The fader position will also affect the strength of the caller in the cue
output, if the caller is set up via the CALLER dipswitch for post fader cue
(see page 2-9).

ON/OFF Switches
The ON (red) and OFF (white) buttons on the bottom of the panel de-
termine if the phone channel is ON or OFF. The buttons can also be used
to provide external start logic for the hybrid if the caller fader has been
assigned to a logic port.
If the phone channel is OFF, caller signal will not be present in any
main bus output, regardless of the status of the PGM ASSIGN buttons or
the position of the fader. If the phone channel is OFF its signal will still be
present in the cue output if it has been assigned to cue.

Caller Set-Ups
Pre-air segment communication between the console operator (DJ)
and caller is aided by the COM button, which places the caller’s voice on
the console’s cue speaker and headphones, and (if so programmed) CR
speakers. This cue signal can be programmed pre or post fader.
The DJ can assign his microphone input channel to an unused out-
put bus—say PGM 3—and the DJ then selects the PGM 3 bus with the
CALLER FEED switch. This sends a dedicated (digitally generated)
version of the PGM 3 bus signal to the caller’s hybrid output, where it
is ultimately heard by the caller through his telephone. This mix minus
source select method can also be used to preplay a musical segment (or
any other program content) for the caller off-air. Take the input channel
handling the desired music cut and assign it to the same bus as the caller’s
mix minus source and the caller will hear it off-air.
For convenient handling of call-ins, the console is capable of driv-
ing the PGM 3 bus with a pre-fade signal from any input channel 1-12
so programmed (see page 2-6). That way, when you use PGM 3 as the
caller FEED source, the DJ mic, and any other inputs you want the caller
to hear, do not need to be faded up for the caller to hear them, as long as
those inputs are assigned to PGM 3 and programmed for PGM 3 pre.
Regardless of any input PGM 3 pre setting, the caller audio to the PGM 3
bus is always post-fade, post-on.
The DJ microphone input channel can also be assigned via dipswitch
to the console’s talkback (TB) bus. Any audio on the TB bus is heard by
a caller when the caller COM button is pressed.

Monitor Section
The Control Room is the monitor that allows
the operator to listen to the console’s three ste-
reo Program outputs and an external stereo line
level input. This section of the console includes
the monitor level controls for the control room,
headphone, and cue circuits, the TB level, and
the Studio level.
In a typical radio application the console
is located in the Control Room. Speakers in
the Control Room allow the console opera-
tor to listen to the console bus outputs to be
assured that the console is performing as de-
sired. These speakers are fed by a stereo sig-
nal from the console’s Control Room output.
In addition to the Control Room output, the
operator may also desire to listen to specific
isolated faders via the cue system and the
console’s internal cue speaker, or may want
to listen via headphones. Thus, the control
room monitor consists of the above mentioned
level controls, along with three program assign
(PGM 1, PGM 2, and PGM 3) buttons, and an
external input (EXT) button.
In some instances the console operator may
also be performing talent whose voice will be
heard over the radio. The operator’s micro-
phone may thus provide a part of the signal that
is going out over the air. If that signal is the
one being monitored with the Control Room
speakers, there is the potential for feedback.
The amplified signal from the Control Room
speakers is picked up by the microphone and
preamplified to a new, higher, level, which then
is once again picked up by the microphone. The
signal quickly rises to an ear-splitting screech.
To prevent this, the operator’s microphone is normally set to MUTE the Control
Room output to prevent the occurrence of feedback.
The master CUE circuit drives a meterbridge-mounted speaker through a
built-in power amp, and can be programmed to interrupt control room feed, or
provide a split feed (program mono sum to right, cue mono sum to left) to the
control monitor speakers. It also automatically interrupts the headphone feed.
In addition to the Control Room, there may be a Studio in which one or more
performers will be assembled, usually with microphones so that their voices
can become part of the mix. Speakers may be provided in the Studio to allow
the talent to listen to the console bus outputs at times that they are not actually
on air. These speakers are fed from the console’s stereo Studio output.

Control Room Program Select

Pressing any of the three program
(PGM 1, PGM 2, or PGM 3) switches in the
Control Room section allows the operator to
listen to the selected output bus. The selected
output bus will normally also be heard in the
studio. The button will be lit when the monitor
is assigned to its respective bus.

Control Room EXT Switch

Pressing the control room EXT switch al-
lows the operator in the control room to pick
up the external balanced input (useful for such
items as tape recorders or air returns) to listen.
The control room EXT button will light and the
selected PGM button light goes off.

Control Room Level Control

The CONTROL level control determines the
overall loudness of the signal being monitored
as it appears in the Control Room speakers.
As the control is turned clockwise, the loud-
ness increases up to a maximum at the limit of
mechanical rotation. To decrease the loudness,
turn the control in a counterclockwise direction.
NOTE: If the control room is muted and you
turn the level control all the way up, then
remove the condition that has the Control
Room muted, the sound in the control room
speakers will suddenly be VERY LOUD!

Cue Level Control

The CUE level control determines the over-
all loudness of the cue signal as it appears in
the console’s cue speaker (located behind the
grill in the meterbridge).
Like the control room speakers, the cue speaker also has the potential for
feedback. To avoid this situation, operator mics that mute the control room
will also mute the cue speaker if the CUE MUTE position of the MONITOR
1 dipswitch has been set to enable the cue muting function (see page 2-10).
NOTE: If cue is muted and you turn the level control all the way up, then
remove the condition that has the cue muted, the sound in the cue speaker
will suddenly be VERY LOUD!

Headphone Level Control

The HEADPHONE level control deter-
mines the overall loudness of the headphone
output signal, which monitors the same source
(PGM 1, PGM 2, PGM 3, or EXT) as the control
room speakers.
The headphone output signal appears at the
HEADPHONE JACK, located beneath the arm-
rest near the right side of the console. The jack
is provided as a place to plug in user-supplied
stereo headphones having an impedance of 60
ohms or higher.

Studio EXT Switch

The studio monitor essentially works in one
of two modes. In External mode, as indicated
by the Studio EXT button being lit, the Stu-
dio output monitors the same external audio
source that is available to the Control Room,
regardless of what source is actually selected
for Control Room.
In the Control Room Follow mode, as in-
dicated by the Studio EXT button being off,
the Studio output monitors the same source
that has been selected for monitoring by the
Control Room.
Toggling between the two modes is ac-
complished by pressing the Studio EXT button
until it is on or off as desired.

Studio Level Control

The STUDIO level control determines the
overall loudness of the signal being monitored
as it appears in the Studio speakers.

TB (Talkback) Button
The TB button lets the operator’s microphone signal interrupt the normal
feed to the studio speakers.
There may be times when the console operator wants to talk to one of
the performers in the Studio. When the TB button in the Studio is pressed
(it is momentary action), any inputs assigned to the talkback bus (see page
2-11) will interrupt the regular monitor signal being sent to the studio output.

TB Level Control
The TB master level control sets the level of the talkback interrupt signal.

Meters (VU-X12)
The METERS section consists of two VU meter pairs on the console’s
meterbridge, and three METERS select buttons, plus a CUE indicator,
located on the Master panel.

VU Meter Pairs
The two VU meter pairs (PROGRAM 1 VU and SWITCHED VU)
are stereo LED bargraph type meters.
The level of the signal being metered is indicated by the number of
display elements that are lighted. The more elements lighted, the stronger
is the signal being displayed. The right four LEDs in each bargraph are
red to indicate when the signal level is approaching a clipping (distorted)
level. The next four LEDs are yellow, indicating a normal level range,
and the remaining LEDs are green. The top member of the pair indicates
the level of the signal’s left channel, while the bottom member of the pair
indicates the level of the signal’s right channel. Peak (CLIP) indication
is also provided.
The left VU meter pair shows the level of the PGM 1 output, while
the right VU meter pair (the SWITCHED VU) allows the console opera-
tor to meter PGM 2, PGM 3, or the console’s external stereo line signal
(analog, +4dBu balanced).
The Master panel also has a master CUE indicator. Whenever any input
channel is placed in cue the CUE indicator lights. At the same time the
switched meter pair automatically switches to show the level of audio on
the cue bus. While the CUE indicator is lit, the selected switched meter
source switch light goes off.

Meters Select Buttons

The METERS buttons select the source for the switched meter pair,
as indicated above.
