5.1.1 Limiter

limiter limits the volume at the maximum undis-
torted level . If the LED lights permanently, use the
control LEVEL (20 or 26) to reduce the volume .
5.1.2 Volume attenuation during
microphone announcements
During microphone announcements, the volume
of the MP3 / CD player and of the audio unit con-
nected to the jack LINE IN (24) can be attenuated
automatically . This will make it easier to under-
stand announcements .
1) Use the switch MUSIC RETURN TIME (28) to
attenuate the volume:
LONG After an announcement, the attenua-
tion will be deactivated with a delay .
OFF
no attenuation
SHORT After an announcement, the attenua-
tion will be deactivated immediately .
2) Use the control DEPTH (29) to adjust the level
of attenuation . When the control is set to the
left stop, the volume will not be attenuated .
When the volume is attenuated during an an-
nouncement, the green LED on the left of the
control will light up .
5.2 Operation of the receiver module
Each receiver unit (A and B) provides a control
(2) to adjust the volume and to switch it on and
off . The display (1) is divided into two parts: left
half for receiver unit A, right half for receiver unit
B . When a receiver unit has been switched on,
the display will indicate the transmission channel .
To briefly indicate the radio frequency, press the
button
(for unit A) or
(for unit B) .
5.2.1 Setting the transmission channels
Use the controls (2) to switch on the receiver
units . Do not switch on the corresponding wire-
less microphones / transmitters for the time being .
Channel scan

interference . If no free channels are found, the
channels set will be kept .

both
receiver units A and B are switched on:
1) Keep the button SET (3) pressed until the chan-
nel indication for receiver unit A starts flashing
