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 4004 FX 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 through 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.
