OPERATION

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 speaker system. The POWER indicator lights up.
After operation, switch off the speaker system first.
3
Switch on the wireless receiver. 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 speaker 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 speaker 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
Adjust the desired sound with the tone controls. By adjusting the tone controls, the high frequencies
(control HI) and the low frequencies (control LOW) can be boosted or attenuated. With the controls in
mid-position, the frequency response is not affected.
7
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.
8
After operation, switch off the speaker system. The POWER indicator extinguishes. 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 sliding switch to the "OFF" position.
