Installation
Ventilation
The M-Class was designed to be placed on a table or rack-mounted.When rack mounted, the amplifiers can be
stacked one on top of the other for maximum use of the rack.
An open air space of at least 4" must be provided at the front air intakes of the amplifier, and the rear exhaust
must have at least a 4" gap from any obstructions to ensure adequate cooling. This applies to both rack-
and table-mounted amplifiers.
Care should also be taken to ensure that the front intake air is not considerably warmer than the ambient air
temperature. Mount the amplifiers low in the rack so that heat dissipation from other equipment does not
warm the amplifier's intake air.
Rack Mounting
Rack ears are included with the amplifier to allow
mounting in 19" racks. Attach the rack ears as
shown in the Installation Components section. If any
feet have been attached to the bottom of the
amplifier, remove them. Load the amplifier into the
rack and secure it to the rack with appropriate
hardware (not included).
Rear Rack Mounting
For greater rear support when rack mounting an
M-Class amplifier, the RPK86 Rack Mounting Kit
(not included) can be attached to the rear of the
amplifier by following the steps below.
1.
Remove and save the three cover screws 
from the chassis of the amplifier.
2. Position the rack attachment as shown.
3. Replace and tighten the three cover screws 
to secure the rack attachments.
Table Mounting
Feet are provided with the amplifier to allow it to
be placed on a tabletop. Attach the included feet
to the bottom of the amplifier as shown.
Attachment of the rack ears to the unit is option-
al and purely aesthetic for table mounting.
