4. Installation
The common installation of the amplifier is in rack
cabinets: to limit the risk of mechanical damages,
the amplifiers must be fixed to the rack using both
frontal and rear mounting brackets.
Note: instead of connecting the amplifier to the
power grid directly, plug the amplifier’s mains
connection into a power distribution panel inside the
rack cabinet.
4.1. Cooling
Install the amplifier in a well-ventilated location: the
ventilation openings must not be impeded by any
item such as newspapers, tablecloths, curtains, etc;
keep a distance of at least 50 cm from the front and
rear ventilation openings of the amplifier.
TDC series amplifiers implement a forced-air cooling
system to maintain low and constant operating
temperatures. Drawn by the internal fans, air
enters from the front panel and is forced over all
components, exiting at the back of the amplifier.
The amplifier’s cooling system features “intelligent“
variable-speed DC fans which are controlled by the
heatsink temperature sensing circuits: the fans’ speed
will increase only when the temperature detected
by the sensors rises over carefully predetermined
values. This ensures that fan noise and internal dust
accumulation are kept to a strict minimum.
Should however the amplifier be subject to an extreme
thermal load, the fan will force a very large volume of
air through the heat sink. In the extremely rare event
that the amplifier should dangerously overheat,
sensing circuits shut down all channels until the
amplifier cools down to a safe operating temperature.
Normal operation is resumed automatically without
the need for user intervention.
In case a rack with closed back panels is used, leave
one rack unit empty for every four installed amplifiers
to guarantee adequate airflow.
4.2. Cleaning
Always use a dry cloth for cleaning the chassis and the
front panel. Air filter cleaning should be scheduled
according to the dust levels in the amplifier’s
operating environment.
Disconnect the AC mains source
before attempting to clean
any part of the amplifier
TDC series amplifiers are equipped with a magnet-
held front panel. Pull the front panel to remove it, and
retrieve the vent filter. The vent filter can be cleaned
using compressed air, or it can be washed in warm
water. Let the filter to thoroughly dry out before
returning it to the amplifier
