Installation and Placement
Importance of proper ventilation
For placement of the amplifier, keep the following in mind:
• Make sure that air can circulate freely from left to right for adequate ventilation. There are vents on the sides.
• The temperature of the rack should be controlled to ensure that amplifiers are not exposed to ambient temperatures
exceeding 40° C (104° F).
• Do not cover or block amplifier vents.
• Do not place the amplifier in an enclosed space, such as a cabinet.
• Make sure the chassis is protected from heat and kept away from direct heat sources, such as heating vents
and radiators.
CAUTION: Do not allow the chassis to exceed the maximum operating temperature of 40° C (104° F). Be aware of
conditions in an enclosed rack that may increase the temperature above room-ambient conditions. If the amplifier
becomes too hot, it will go into a thermal protection mode and mute all outputs.
Removing rack-mount ears
Rack-mount ears can be removed by removing the three screws from each rack-mount ear.
Placing on a flat surface
The amplifier can be placed on a flat, stable surface like a table, counter, or shelf. The rack-mount ears can be removed
and plastic feet (included with the amplifier) can be installed to protect the surface area and prevent the chassis
from sliding.
Note:
When installing the amplifier in an office, conference room, or classroom, carefully place it in a way that minimizes the audible
affects of the internal cooling fan of the amplifier. It is recommended to place the amplifier below ear level, in a corner, with the
fan inlet (left side) pointing away from the seating area.
