switching-on noise. Then switch on the PA monitor. The
PWR
indicator lights
2
Turn up the
MASTER
control so that the mixing ration of the signal sources can be adjusted in an
optimum way.
3
Adjust the desired volume ratio with the level controls
MIC
and
LINE LEVEL
of the microphone channel
and the line input. Only turn up the controls to such an extent that the sound reproduction will not be
distorted. The
LIMIT
indicator lights up when the signal level is too high so that the level limitation will
be activated. If this indicator lights up frequently, reduce the volume of the input signals accordingly.
4
Adjust the desired volume for the subwoofer with the control
SUBWOOFER LEVEL
.
5
Should a turn of phase occur during the signal transmission, the phase between subwoofer signal and
column speaker signal can be turned by 180° with the
PHASE s
elector switch.
6
Adjust the definite level of the overall volume with the
MASTER
control.

When operating the PA system, please make sure that the loudspeakers always sound well. When
distortions can be heard, either the amplifier or the loudspeakers are overloaded. Overloads can quickly
lead to amplifier or speaker damage. In order to avoid damage, please reduce the volume immediately
when distortions can be heard. When speaker systems are destroyed by overload, the guarantee
becomes void. Always check the sound pressure level with a meter in order to keep to the threshold.

After operation, set the
MASTER
control to minimum, then switch off the PA system with the power
switch. The power indicator extinguishes.
