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). The rack you use should be a Double-Door-Rack where you
can open the frontpanel and the rear panel. 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.
