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. If
only the red LED of the battery indicators lights up during battery operation, the battery must be
charged soon. After operation, switch off the PA system first.
3
Prior to operating the PA system off mains for the first time, the rechargeable batteries must be fully
charged (

6).
4
To switch on the wireless microphones, set the individual sliding switch to the “ON” position. The battery
indicator lights up green. If it lights up red, new batteries must be inserted.
After switching on the microphones, a radio connection to each receiver unit is set up. The reception
indicators
RF.A and RF.B indicate that a connection exists to the corresponding microphone.
As the transmission quality depends on local conditions, please observe the following items for optimum
receiving:
• maintain a line-of-sight between the microphones and receiver antennas.
• make sure the distance between the microphones and the receiver 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.
5
Adjust the MASTER LEVEL control to a level that the subsequent adjustments can be heard well via
the PA system.
6
Adjust the desired volume ratio of the signal sources with the level controls. Turn the controls of the
inputs not used to MIN.
Caution! Do not direct any microphones to speakers. This can result in dangerous and unpleasant
acoustic feedback which will generate a loud whistling sound.
7
Optimize the sound of the mixed signal with the equalizer.
8
A reverb effect created via the integrated effect processor can be added to a microphone signal of the
MIC 1 and MIC 2 inputs and the wireless microphones. Adjust the effect intensity with the ECHO
control.
9
Determine the definite level for the master volume of the PA system with the MASTER LEVEL control.
In case of overload the red CLIP indicator lights up. If it lights continuously, turn back the master control
accordingly.
10
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 microphones. Otherwise the batteries will be
exhausted the next time the microphone is used. To switch off the microphones, set the individual
sliding switch to the “OFF” position.
