c) To set the channel number, press the but-
ton SET repeatedly until the numerals for
CHANNEL start flashing.
d) Set the channel number with the button
or . Once the numerals stop flashing, the
channel setting has been stored.
3) If one of the LEDs ANTENNA A or B (2) lights
up while the transmitter (wireless microphone /
pocket transmitter) is still switched off, inter-
fering signals or signals from another wireless
system are received. In this case, set a differ-
ent channel.
4) Switch on the transmitter and point the IR
sensor of the transmitter towards the IR LED
(4) on the receiving part (see instruction man-
ual of the transmitter, if required). The dis-
tance must not exceed 1.5 m. Make sure that
there are no obstacles between the sensor
and the IR LED.
Briefly press the button ACT (5). The dis-
play backlight of the transmitter is activated.
Thus, the transmitter and the receiving part
are set to the same channel.
5) After the receiving part and the transmitter
have been set to the same transmission
channel, one of the LEDs ANTENNA A or B
(2) lights up on the receiving part, depending
on the antenna receiving the most powerful
signal. If none of the LEDs lights up, please
check:
a Are the batteries of the transmitter ex-
hausted?
b Is the reception disturbed by metal objects
in the transmission path?
c Is it possible to improve the reception when
you turn the receiving antennas?
d Is the distance between the transmitter and
the receiver too long?
e Has the interference suppression been set
too high with the control SQUELCH (11)?

4.3 Setting the mixing ratio of the
microphone signals
The mixed signal of the four receiving parts is
present at the jack LINE OUT (13). To set the
mixing ratio of the individual signals, it is possi-
ble to change the volume of the four microphone
signals separately. For this purpose, first set
the signal to be heard at the highest volume in
order to match the output level of the jack LINE
OUT to the input of the subsequent unit at the
same time. Then add the other microphone sig-
nals.
1) Switch on the audio unit following the receiver
or advance the corresponding control of the
mixer.
2) Press the button SET (6) three times so that
the numerals for VOL start flashing.
3) Speak / sing into the microphone. While the
numerals keep flashing (a few seconds after
pressing the button SET, or
ume with the button or
00 – 63].
Note: If the numerals stop flashing before you have
set the volume, press the button SET three times
again.
4) Once the numerals stop flashing, the setting
has been stored.
4.4 Setting the interference
suppression
With the control SQUELCH (11), adjust the
threshold value for response of the interference
suppression. The interference suppression will
mute the receiving part during pauses in speech
or vocals when interfering signals are received
and their levels are below the threshold value
adjusted. A high threshold value, however, will
also reduce the range of the microphone system:
If the power of the radio signal falls below the
threshold value adjusted, the receiving part is
also muted. Therefore, adjust a high threshold
value (turn the control towards MIN) when the
reception is good and a low value (turn the con-
trol towards MAX) when the distance between
the transmitter and the receiver is long.
