Rack Mounting
Before mounting the amplifiers, ensure that power to the amplifier is turned off.
Turn off all other equipment and disconnect the power cables. Verify that the amplifier is disconnected from the power source
before proceeding.
The XPA U Full-Rack Series ships with two rear rack ears to provide additional stability and support for the amplifier. Each rear
rack ear attaches to the amplifier by means of two SEMS screws that connect though slots in the two support flanges on the
enclosure that extend past the rear panel, through the slots in the rear rack ear and into the backing plate. The backing plate
comes loosely attached to the rear rack ear, which allows it to slide along the slots. The rear rack ears will support rack rail
depths of 15.69" (399 mm) to 26.34" (669 mm), as measured from outward-facing surfaces of the front and rear rack rails.
