INSTALLATION
Please note: when using a PA-system in public or industrial areas, a series of safety instructions have to be
followed that this manual can only give in part. The operator must therefore inform himself on the current
safety instructions and consider them.
Rack installation
This amplifier is built for 19" racks (483 mm). This rack should be a Double-Door-Rack where the front panel
and the rear panel can be opened. The rack should be provided with a cooling fan. When mounting the
amplifier into the rack, please make sure that there is enough space around the device so that the heated air
can be passed on. Steady overheating will damage your device.
You can fix the amplifier with four screws M6 in the rack.
Be careful when mounting the amplifier into the rack. Put the heaviest devices into the lower part of the rack.
Be aware that fastening the amplifier with four screws on the front panel is not enough. In order to ensure
safety, additional fastening by using ground and side bars is necessary.
If racks are to be transported or used for mobile use, additionally fasten the devices by connecting the rear
brackets with the side or ground bars of the rack. In this way, the amplifier cannot be pushed backwards.
The front panel alone is not designed to absorb acceleration forces occuring during transportation.
Inputs
A good cable run improves the sound quality remarkably. Input cables should be short and direct, since high
frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may
lead to humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables.
Professionals recommend to connect the input-cables via balanced XLR-jacks.
Speaker connection
Please note: cabling a PA-system is an electric installation which
must only be carried out by a qualified electrician.
