 Basic functions of the Sennheiser operating menu
A special feature of the Sennheiser evolution wireless series ew 500 is the
similar operation of transmitters and receivers. In stressfull situations, for
example on stage or during a live show or presentation, it is important that
the devices are easy to operate and that adjustments to the settings can be
made quickly and "without looking". Therefore, the necessary operating steps
for each device are similar.

Important:
With the buttons you can directly switch between the factory-
preset fixed frequency memories (presets). The display starts Hashing.
Your selection becomes effective immediately.

Press the SET button to enter the top menu level:

By briefly pressing SET again, you can change to the next menu.
After approx. one second, the selected menu appears on the display
and then the current setting of the menu is indicated.

0 Press the buttons to adjust the settings of the selected menu:

The new setting starts flashing on the display. If you return to the
previous setting, the flashing stops.

Important:
New settings become effective immediately and will be re-
tained in memory on switch-off!
N.B.: When changing transmitter frequencies, care should be
taken to avoid causing interference to other channels/users.

In the "TUNE", "CH NO" and "NAME" menu, the buttons feature a
"fast search" function. By briefly pressing the A buttons, the display
jumps either forwards or backwards to the next setting. If you hold
down a button, the cycling of the display is continously accelerted. If
you release the button and start over again, the cycling of the display
restarts at normal speed. The "fast search" function allows you to get
fast and easily to your desired setting.

Press the SET button to return to the top menu level:

Have you finished your entries? Press the SET button to return to the
top menu level. The display then switches back to the standard setting.

Overview of menus
To ensure that transmitters and receivers of the Sennheiser evolution wireless
Series ew 500 are easy to operate, the operating menus have been largely
standardised:

73
 Selecting a frequency memory-selecting the frequency,
channel number, name (EM 500 only)
With the A./V buttons you can directly switch between the factory-
preset fixed frequency memories (presets). The display starts flashing.
Your selection becomes effective immediately.

Press the SET button to acknowledge your selection. The display stops
flashing. (If the SET button is not pressed, the receiver will store the
new frequency automatically on switch-off).

Note:
You can choose the content of the standard display i.e. whether the
frequency, the channel number or a name is displayed (the latter option
is only possible with the EM 500 receiver) "Selecting the content
of the standard display"). The receiver is factory-preset to show the
frequency setting as standard.

SenSit Adjusting the sensitvity (transmitters only)

Close talking distances, speakers with loud voices or loud music sequences
may cause overmodulation in the transmission link, resulting in distortion.
In this case, the "PEAK" warning of the EM 500's AF level display (as well as
the SK 500 transmitter's yellow audio peak indication LED) will light up. If,
on the other hand, the sensitivity is adjusted too low, the transmission link
will be undermodulated, which would result in a signal with high background
noise.
The sensitivity has to be adjusted such that the "PEAK" warning of the
receiver's AF level display only lights up during the loudest passages.
The following figures are a guide to the best settings:

Loud music/vocals: -30 / -20 dB

Presentations: -20 / -10 dB
Interviews: -10 / 0 dB

Select the "SEnSit" menu by pressing the SET button until "SEnSit"
appears on the display; after a short pause the current input sensitivity
setting is displayed.

With the V buttons you can now select a different setting. The
sensitivity can be adjusted in 10-dB steps from 0 to -30 dB. The new
setting starts flashing on the display and becomes effective immediately.

Press the SET button to return to the top menu level. The display
then switches back to the standard display.

74
SQELCH Adjusting the squelch threshold (receivers only)
SqELCH The Sennheiser evolution wireless series ew 500 receivers are equipped with
an adjustable squelch which eliminates annoying noise when the transmitters
are switched off. It also suppresses sudden noise when a transmitter leaves
the reception area and there is no longer sufficient transmitter power received
by the receiver.

Select the "SQELCH" menu by pressing the SET button until "SQELCH"
appears on the display; after a short pause the current squelch setting
is displayed.

With the buttons you can now select a different setting. The
squelch can be switched off (0 dB) or adjusted in 5-dB steps from
5 dB to 40 dB. Selecting a smaller value reduces the squelch threshold,
selecting a higher value increases the squelch threshold. The new
setting starts flashing on the display. Set the squelch threshold - with
the transmitter switched off - to the lowest possible value that
suppresses hissing noise. If the squelch threshold is set too high, the
transmission range will be reduced.

Note:
With the transmitter switched off and the squelch threshold set to
"0 dB" hissing noise will occur. With the EM 500 receiver, the "PEAK"
warning ofAF level bargraph will light up.

> Press the SET button to return to the top menu level. The display
then switches back to the standard display.

Att Selecting the sensitivity range (SKP 500 only)

Condenser microphones require a different sensitivity range than dynamic
microphones. With the SKP 500 plug-on transmitter, you can switch the
sensitivity range by 20 dB.

Select the "Att" menu by pressing the SET button until "Att" appears
on the display; after a short pause the current setting - i.e. "Att off" or
"Att on" - is displayed.
With the A/V buttons you can now switch between two different
sensitivity ranges.
Sensitivity range 1 for dynamic microphones
- "Att off" flashes on the display
Sensitivity range 2 for condenser microphones
- "Att on" flashes on the display
Press the SET button to return to the top menu level. The display
then switches back to the standard display.
Note:
For recording of quieter signals (e.g. wildlife) with a condenser
microphone, you may find it better to set the sensitivity to "Att off".

75
 SCM Doing the soundcheck (EM 500 only)
By doing a soundcheck you can check the reception area for field strength
gaps ("dropouts") which cannot be compensated for by the EM 500's diversity
circuitry. The EM 500 enables you to do the soundcheck without the help of
another person.

Make sure that the corresponding transmitter is switched off.

Switch the receiver on.

Choose the setting "RF/AF" in the "BARS" menu and set the squelch
threshold to at least "5" (dB).

Select the "SCM" menu by pressing the SET button until "Sound Check
Mode, Repeat, END" appear running across the display and the
soundcheck starts.
Switch the transmitter on and walk up and down the transmission
area.
You can now check the results of the soundcheck on the receiver. If
the "MUTE" display is lit up, "dropouts" have occured. The bargraph
displays will indicate the lowest RF and the highest AF level. The
displays "I" and "II" indicate that both receiver sections are active.

If "dropouts" have occured, you now have to find out where exactly
the reception is subject to interference.
If only one receiver section is indicated, check the antenna connections.

You must then repeat the soundcheck for smaller sections of the area.
To do so, press the button. "REPEAT" appears on the display. Repo-
sition the antennas and press the SET button. The soundcheck starts
over again and the previously measured data are then deleted.
To terminate the soundcheck, press the button. "END" appears on
the display.

Press the SET button to return to the top menu level. The display
then switches back to the standard display.

76
PHAnto Switching the phantom powering on/off (SKP 500 only)
The SKP 500 transmitter can supply condenser microphones with 48 V
phantom powering (P 48). Please note: Dynamic microphones can be operated
in phantom powering mode without harm. However, if no condenser
microphone module is being used, you should switch off the phantom
powering. With the phantom powering switched on, the operating time of
the battery will be reduced to approx. 5 hours.

The phantom powering can be switched on or off via the operating menu:

Select the "PHAnto" menu by pressing the SET button until "PHAnto"
appears on the display; after a short pause the current setting is
displayed.

Press the button to switch the phantom powering on - if you press

the button, the phantom powering is switched off. The new setting
- i.e. "ON" or "OFF" - starts flashing on the display.

Press the SET button to return to the top menu level. The display
then switches back to the standard display.

77
 BARS Selecting the function of the bargraph displays (EM 500 only)
Generally, the EM 500's two bargraph displays are programmed such that
the upper bargraph indicates the RF level, while the AF level is indicated by
the lower bar. You can, however, program the bargraph displays so that they
indicate the RF levels of the two receiver sections.

Select the "BARS" menu by pressing the SET button until "BARS"
appears on the display; after a short pause the current setting is
displayed.

With the buttons you can now change the function of the bargraph
displays:
RF level of both receiver sections -
"RF 1/11" appears on the alphanumeric main display
RF and AF level -
"RF/AF" appears on the alphanumeric main display

Press the SET button to return to the top menu level.

If the bargraphs indicate the RF levels of the two receiver sections,
the displays RF, I and II on the left of the bargraphs light up.
If the bargraphs indicate the RF and AF level, the displays RF and AF
on the left of the bargraphs light up.
The display then switches back to the standard display.

Ltd Limiting the volume at the headphone output (EK 500 only)
In the "Ltd" menu, you can choose the standard volume at the EK 500's
headphone output. With the limiter switched on, the maximum volume at
the headphone output will be reduced by approx. 15 dB.

Select the "Ltd" menu by pressing the SET button until "Ltd" appears
on the display; after a short pause the current setting is displayed.

Press the A button to switch the limiter on - if you press the button,
the limiter is switched off. The new setting - i.e. "Ltd on" or "Ltd OFF"
- starts flashing on the display.

Press the SET button to return to the top menu level. The display
then switches back to the standard display.

Note:
The limiter setting has no effect on the LINE output.

78
DISPL Selecting the content of the standard display
DiSPL With all transmitters and receivers you can choose the content of the standard
display i.e. whether the frequency, the channel number or a name is displayed
(the latter option is only possible with the EM 500 receiver).

Select the "DISPL" menu by pressing the SET button until "DISPL"
appears on the display; after a short pause the current setting is
displayed.
