OPERATION
1
First turn down all level controls of the input channels and the effect controls to the left stop position.
2
Use the input selector buttons to switch the channels 1 to 4 to microphone or line level according to the
signal sources connected. The wireless microphones use channels 2 and 4.
3
Adjust the MASTER LEVEL control for the overall volume to a level that the subsequent adjustments
can be heard well via the speakers.
4
Adjust the desired volume ratio of the input channels with the VOL controls. Turn the controls of the
inputs not used to 0. In case of overload the red LED PEAK lights up. If it lights red continuously,
reduce the level of the signal sources accordingly.
5
Adjust the desired sound with the tone controls. By adjusting the tone controls, the high frequencies
(control TREBLE) and the low frequencies (control BASS) can be boosted or attenuated. With the
controls in mid-position, the frequency response is not affected.
6
Determine the definite level for the master volume of the PA system with the MASTER LEVEL control.
In case of overload the red LEDs LIMIT light up. If a LED lights continuously, turn back the master
control accordingly.
7
For optimum receiving of the radio signal:
• 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 batteries of the hand-held microphone are always sufficiently charged.
Adding an Echo Effect
An echo effect created via the integrated effect processor can be added to the signal of the input channels 1
to 4.
1
With the REVERB controls, adjust the signal part for each channel which is to be fed to the internal
effect processor. The further the control is advanced, the more powerful is the effect for the channel.
The effect level is also dependent on the channel volume adjusted with the VOL control.
2
With the REV.RETURN control adjust the overall intensity of the echo effect.
CAUTION!
Do not direct any microphones to the speakers. This can result in dangerous and
unpleasant acoustic feedback which will generate a loud whistling sound.
