RACK MOUNTING

The amplifier is built for 19" racks/483mm. You can fix the amplifier with four screws M6 in the rack.
When mounting the amplifier into a rack, please make sure that there is a proper air circulation. Steady
overheating will damage your device. The amplifier's total power consumption consists of the output
power passed on to the speakers and the power loss which has to be passed on to the air in the form of
heat. Please make sure that there is enough space around the device so that the heated air can be
passed on. The rack should be provided with a cooling fan. Your amplifier additionally features built-in
cooling fans that supply the necessary ventilation. Since the heated air is passed on through the
device's rear panel, the back of the rack should be left open during operation. Be careful when mounting
