OPERATION

PA System

1
Prior to switching on, turn down the master control MASTER LEVEL for the overall level to the left stop
position to avoid a possible switching-on noise.
2
First switch on the connected audio sources, then the PA system. The POWER indicator lights up. After
operation, switch off the PA system first.
3
Switch on the wireless receiver with the WIRELESS button. Then set the sliding switch on the
microphone to the "ON" position. The power indicator lights. If it fails to light up, new batteries must be
inserted. If the reception of the radio signal is of sufficient power, the reception indicator RF on the PA
system lights up. Adjust the desired volume of the audio signal received with the control LEVEL. To
mute the microphone during operation, set the sliding switch to its center position "MUTE". Then no
sound will be transmitted.
Note
As the transmission quality depends on local conditions, please observe the following items for optimum
receiving:
• maintain a line-of-sight between the microphone and the PA system.
• make sure the distance between the microphones and the PA system is not too long.
• make sure the reception is not disturbed by objects in the transmission path; avoid placing the
microphones and the receiver where metal or other dense materials may be present and computers or
other HF-generating equipment (min. 50 cm distance).
• make sure the capacity of batteries is always sufficient.
4
Adjust the MASTER LEVEL control to a level that the subsequent adjustments can be heard well via
the PA system.
5
Adjust the desired volume ratio of the signal sources with the level controls. Turn the controls of the
inputs not used to zero.
Note
Do not direct any microphones to speakers. This can result in dangerous and unpleasant acoustic
feedback which will generate a loud whistling sound.
6
Optimize the sound of the mixed signal with the TONE control.
7
A reverb effect created via the integrated effect processor can be added to a microphone signal of the
MIC input and the wireless microphone. Adjust the effect intensity with the ECHO LEVEL control.
8
Determine the definite level for the master volume of the PA system with the MASTER LEVEL control.
In case of overload the red PEAK indicator lights up. If it lights continuously, turn back the master
control accordingly.
9
After operation, switch off the PA system. The POWER indicator extinguishes. The automatic charging
for the rechargeable battery is always active even if the unit is switched off. To prevent unnecessary
power consumption, always disconnect the mains plug from the mains socket if the unit is not used for a
longer period. Also, do not forget to switch off the wireless microphone. Otherwise the batteries will be
exhausted the next time the microphone is used. To switch off the microphone, set the individual sliding
switch to the "OFF" position.
