Rack mounting

The PX amplifier can be mounted in an EIA standard rack
(2U size).
Precautions for rack mounting
This device is rated for operation at ambient tempera-
tures ranging from 0° to 40°C. When mounting the device
with other PX amplifier(s) or other device(s) in an EIA
standard equipment rack, internal temperatures can
exceed the specified upper limit, resulting in impaired
performance or failure. When rack mounting the device,
always observe the following requirements to avoid heat
buildup:
• When mounting the unit in a rack with devices such as
power amplifiers that generate a significant amount of
heat, leave more than 1U of space between the device
and other equipment. Also, either leave the open
spaces uncovered or install appropriate ventilating pan-
els to minimize the possibility of heat buildup. Multiple
PX amplifiers can be mounted by stacking vertically.
• To ensure sufficient airflow, leave the rear of the rack
open and position it at least 10 centimeters from walls
or other surfaces. If the rear of the rack cannot be left
open, install a commercially available fan or similar ven-
tilating option to secure sufficient airflow. If you have
installed a fan kit, there may be cases in which closing
the rear of the rack will produce a greater cooling effect.
Refer to the rack and/or fan unit manual for details.
