The diagram opposite shows the thermal operating range within
which the technical data will be maintained. The operation
beyond this range is possible for a short time but for thermal
reasons this may trigger the amplifier protection circuit for
thermal overload.
The D6 and D12 amplifier enclosures are designed to fit a
standard 19" equipment rack or cabinet.
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.
Since the amplifiers 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.
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.
