Installation
Before connecting to mains power, make sure that the switches and wiring are all set to the configuration needed
for your particular application. Failure to do so could result in damage to the unit or other components in your system.
CAUTION: When mounting or connecting the amplifier, always disconnect it from the mains. Use four screws and
washers when mounting the amplifier to the front rack rails. Rear support is also recommended, especially for mobile or
touring use. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
