6. Installation and operation
6.1. Installation
D12 amplifier enclosures are designed to fit a standard 19" equipment
rack or cabinet.
The front panel vent slot serves as a useful handle for lifting and moving
amplifiers in and out of racks. When specifying a rack, be sure to allow
extra depth (10 cm / 4" is usually sufficient) to accommodate the cables
and connectors at the rear of the amplifier(s).
When mounting amplifiers into a 19" rack cabinet, provide additional
support using shelves fixed to the inner sides of the cabinet or the
mounting holes provided on the amplifier rear mounted rack ears - do
not just rely on fixing and supporting amplifiers by their front panels.
This advice is particularly important if amplifiers are being racked up for
touring use.
IMPORTANT!
Since the D12 amplifier can generate a lot of heat, please ensure,
whatever the mounting or racking arrangement, that adequate cool
airflow is provided to avoid a build-up of hot air inside the rack leading
to overheating. When setting up the amplifier, do not block or cover the
rear panel air intake or the vents on the front panel of the amplifier.

We advise frequent cleaning of the fan filter to ensure good airflow
through the unit. If the filter is visibly dirty, then it should be cleaned or
replaced. Never operate the D12 without a filter. Dust deposits,
especially combined with damp conditions, could cause the amplifier to
malfunction. If amplifiers are installed in cabinets so that direct access to
the rear panel filters is not possible, we recommend using additional fan
modules with front mounted filters that can be easily replaced without
opening the sealed cabinets.
