1.
Attach the front rack ears of the amplifier to the front of the rack, using the four provided screws (
2. The rear rack ears are installed into the corresponding position on the rails on the back side of the equipment rack (
3. Slide the backing plate into the slots in the support flanges (
The screws are loosened just enough to allow the backing plate to easily slide into the slots in the support flanges without
getting the washers caught between the flange and the rear rack ear, but not so much that the backing plate is disassembled
from the rear rack ear.
4. Tighten down the backing plate screws.

Rack Mounting Ventilation Recommendations

Excessive heat can decrease the optimal lifetime of the power amplifier. An over temp indicator LED (see
page 6) on the front panel of the amplifier lights red whenever the recommended operating temperature has been exceeded.
To reduce the chances of an over temp condition, the XPA U Full Rack Series Audio Power Amplifiers should be arranged in a rack
environment so the environment around the amplifier does not reach or exceed +122°F (+50°C).
These amplifiers are cooled by forced air, with front to back airflow. Care must be taken not to obstruct the airflow at the intake and
exhaust vents.
