switching-on noise. Then switch on the stage monitor. The POWER indicator lights
2
Adjust the desired overall volume with the MASTER control. Only turn up the control to such an extent

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.

CLEANING AND MAINTENANCE
We recommend a frequent cleaning of the PA system. Please use a soft lint-free and moistened cloth. Never
use alcohol or solvents!
There are no serviceable parts inside the device except for the fuse. Maintenance and service operations are
only to be carried out by authorized dealers. Should you need any spare parts, please use genuine parts. If
the power supply cable of this device becomes damaged, it has to be replaced by a special power supply
cable available at your dealer.
If the stage PA system distorts, one of the loudspeakers may be defective. In this case the system should
not be operated any more in order to prevent further damage. Please contact your dealer. If clacking sounds
are heard from the system, screws may have loosened due to the continuous vibrations. The system should
be checked by a specialist.
Should you have further questions, please contact your dealer.

replacing the fuse, unplug mains lead.

Step 2: Remove the old fuse from the fuseholder.
Step 3: Install the new fuse in the fuseholder.
