1. Introduction
The Mytek USB2 CLASS2 Card is an optional card that is installed into the rear expansion slots of
the Mytek 8X192 ADDA converter. With this card installed the Mytek 8X192 ADDA can be directly
connected to a MAC OS, Linux or Windows computer via USB. The card may be installed by the user
as described further in the manual.

All the best,

The Mytek Digital Team

2. Package Content
• The USB2 CLASS2 expansion card

• EEPROM chip for 8x192 mainboard

3. Features
The extension card offers option of connecting 8x192 ADDA via the USB interface and using this
converter as the audio interface for Windows, Linux and Mac OS.

4. Before You Begin

Before connecting the USB2 CLASS2 card please check if the most current firmware (version 6.3 or
later) is installed in the 8X192 converter. To verify the version, locate the firmware chip (8 pin DIP chip
in a socket near the aluminum heat sink) on the main converter board or contact Mytek if you require
assistance.

In the support section of the Mytek website at: www.mytekdigital.com/download_library you will find
current detailed information about firmware versions and most current firmware and driver update
instructions. If necessary contact Mytek and request appropriate firmware.

5. Quick Start

Remember to turn off and disconnect power and to disconnect

signal cables while working with the top cover removed.

1. Installation of USB2 CLASS2 card

Remove the top cover from the converter, unscrew the DIOCARD1 or DIOCARD2 slot plate
and install the USB card using the existing screws in either slot. If there is a Protools DIO card
installed it will work in slot 1 only. All other DIO cards including USB will work in either slot.
The card must be installed with the components facing up. Double check that all connector pins
match up with the pins of the connector on the main converter board properly. Pin mismatch
may damage the card or converter. Follow detailed installation instructions further below.

2. Driver Installation
Drivers should be installed before the first connection of the converter to the computer. Most
current drivers are available in the download library at www.mytekdigital.com.

3. Connecting the card to the computer

Turn off the ADDA 8x192 converter before plugging in the USB cable. The computer can be left
turned on. After making the connections, the converter can be powered on.

4. Configuration
On first power up of the converters, each converter should be recognized by the computer and
have the driver installed automatically. Further configuration of inputs and outputs is done in
your DAW software.

6. Card Instalation
The DIO USB2 CLASS2 card can be installed in either the DIOCARD1 or DIOCARD2 slot. The card can
be installed together with any other card available for the 8x192 converter. If Protools DIO card is
installed it will work in slot 1 only. All other DIO cards including USB2 CLASS2 will work in either slot.

Before installing the card, check if the converter’s

firmware supports DIO USB2 CLASS2 card (version 6.3 or
later). If not, contact Mytek and request current version.

WARNING!
Remember to follow basic safety rules on electronic device handling while opening
the converter:
• Keep your hands dry,
• If floor is carpeted ground spray surroundings with water mist and ground
your wrist to the chassis before unpacking and handling the DIO card.
• Turn off power and detach power and signal cables while working with the top
cover removed.

7. Connecting Clock Signal Line

7.1 Single Converter
If a single converter is used in the system, using it’s internal clock will provide the best performance
(regardless of what a clock dealer will tell you.) If external clock is used for systemic reasons SAMPLE
RATE must be set to EXT. by pressing and holding EXT CLOCK SOURCE switch.

Attention! In a system with multiple units, double check that the

configuration of clock signal lines, synchronization sources and
sampling frequencies of all converters in the system are correct.

8. Master 8x192 ADDA converter front panel

Check if the selected sampling frequency of the converter (FS) matches the sampling frequency in
Control Panel

Correct clock configuration is necessary for the proper operation of the converters and for the best
sound quality. Make the 1st Mytek in the chain the clock master for the whole studio. There is no
benefit of using a dedicated clock. Clocking off the Mytek’s internal clock generator produces superior
results because the clock and the clock line current drivers are the best in the industry.

Changing external synchronization source while the program is running may result in improper
operation of converters and loud cracks in the analog section.

9. Input Connection
There s one USB port on USB card which should be used for computer connection.

10. Signal Routing

ADDA8x192 converter provides the system with 8 input and 8 output channels. If more than two
channels are used, audio software which understands multichannel I/O must be used.
