Ecler DPA-T SERIES - Manual (Page 5)

5
Ecler DPA2500T/4000T makes use of a twin power supply and 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 DPA2500T/4000T 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 the UCM or AMIC processor modules.
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 is a card that has been specially designed to fit into ECLERs
DPA Series SPM Technology power amplifiers and can be totally configured through Eclers "amic:lab" software. Its
exceptional audio processing features make it a particularly versatile tool:
- Equalizer with 10 filters
- 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 UCM or AMIC processor module inside a DPA
power amplifier.
3. INSTALLATION
3.1. Location, assembly, ventilation
The DPA2500T/4000T amplifiers are 3 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.
3.2. Mains connection
The DPA amplifiers are fed with alternate currents, depending on the country, of 110-120, 220-240V
47-63Hz. (see characteristics in the back of the unit) consuming:
MODEL DPA2500T
DPA4000T
CONSUMPTION 4100VA 6760VA
WARNING!: By convention, the mains wire colour assignment is the following:
- BROWN = Phase
- BLUE = Neutral
- YELLOW/GREEN = Earth
The mains cables must not be near the shielded cables carrying the audio signal, as this could cause
humming.
