Installation; Location, Assembly, Ventilation - Ecler DPA600 Bedienungsanleitung

Ecler DPA2000 makes use of N-channel mosfets. This technology, which has been successfully implemented
in the industrial product line "enviro", allows for very high output power without the use of bridge configurations. The
DPA2000 keeps its "All the Power All the Time" philosophy, even when driving 4 ohm speakers with a musical
programme at maximum level.
The DPA power amplifiers feature an expansion slot at the rear panel which is specially designed for the
installation of a UCM20/AMIC or ALMAcard processor module.
The stereo processor module UCM20 "Universal Crossover Module" is a card that has been specially
designed to fit into ECLERs DPA Series SPM Technology power amplifiers. A power amplifier with built-in UCM20
may reproduce either the low or high frequencies, as required. The two outputs additionally allow feeding the
filtered signal to an external amplifier.
The stereo digital processor module AMIC/ALMAcard has been specially designed to fit into ECLERs DPA
Series SPM Technology power amplifiers and can be totally configured through Ecler "amic:lab"/EclerCOMM
software. Its exceptional audio processing features make it a particularly versatile tool:
- Parametric equalizer, multiband
- Crossover with variable filter slopes
- Delay
- Phase inversion
- Signal generator
- Remote level control
Please refer to your Ecler distributor if you need to install a UCM20/AMIC or ALMAcard processor module
inside a DPA power amplifier.

3. INSTALLATION

3.1. Location, assembly, ventilation

The DPA600/1000/1400/2000 amplifiers are 2 RU high 19'' rack modules.
It is important that the amplifier, as a heat source, is not placed next to other equipment nor exposed to
high temperatures. Therefore, the ventilation path should be kept free to allow fresh air entering the forced
ventilation tunnel. This system takes air from the unit's backside, bringing it directly to the power amp modules and
distributing it to the transformer and capacitors and then obliging it to pass trough the MOSFET cooling tunnel to
finally blow out of the front panel. In case of rack mounting, this system avoids heat accumulation inside the unit
and thus increases lifetime of electrolytic capacitors. It is recommended to place power amplifiers on top of other
equipment and not underneath.
All DPA amplifiers are supplied with plastic washers in order not to damage the rack ears when tightening
the screws.
