5. Installation and operation
NOTICE: Observe the operating conditions and limits as given in the
technical specifications. Please ensure that ...
- no moisture or liquids can enter the unit,
e.g. rain, excessive humidity or steam, oil steam or splashes or
knocked over liquids (e.g. Drinks).
- the unit is not exposed to additional heat,
e.g. excessive heat from additional equipment or direct sunlight
- no dust or other small particles can enter the unit. In combination
with moisture this could lead to malfunction of the unit.
5.1. Rack mounting and cooling
Rack mounting
D6 amplifier enclosures are designed to fit into a standard 19"
equipment rack or cabinet.
When specifying a rack, be sure to allow extra depth (100 mm / 4" is
usually sufficient) to accommodate the cables and connectors at the rear
of the amplifier.
When mounting amplifiers into a 19" rack cabinet, do not just rely on
fixing and supporting amplifiers by their front panels. Provide additional
support ...
- using shelves fixed to the inner sides of the cabinet or rack
- or the mounting holes provided on the amplifier rear mounted rack
ears. This is particularly important if amplifiers are being racked up
for touring use.
Cooling
Thermal conditions are a vital factor ensuring operational safety of the
power amplifier. The D6 amplifier has an internal fan that draws cool
air into the housing from the rear. It expels heated air through the vents
on the front panel.
- Please ensure that adequate cool airflow is provided to avoid a
build-up of hot air inside the rack leading to overheating. 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 sealed cabinets (e.g. in fixed installations)
use additional fan modules with filters that can be easily replaced
without opening the sealed cabinets.
