Operation At 2Ω; Cleaning - Ecler DT 4800 Notice D'emploi

4.5. Operation at 2Ω
Operation at 2Ω considerably reduces the sound quality and the system efficiency; e.g., the loss on
the loudspeaker cable reduces the Damping Factor by a 76% because of operating at 2Ω instead of 8Ω.
Almost all the amplifiers in the market base their operation at 2Ω on the use of destructive
protections to keep the components safe, with the penalty of sound quality. Also, and for both technological
and power supply constraints, the power gain involved in operation at 2Ω instead of 4Ω is usually very low.
ECLERs DT Digital Trilevel amplifiers are able to operate at 2Ω keeping its philosophy of non-
destructive protections and delivering every Watt the power supply is capable of.
ECLER, following the maximum sound quality criterion, recommend using the 2Ω connections only
in installations where the amplifier will operate far from its maximum power.
Continuous operation at 2Ω with stationary signals can cause the activation of the protection
systems.

5. CLEANING

The front panel should not be cleaned with solvents or abrasive substances because silk-printing could be
damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid soap; dry it with a clean
cloth. Be careful that water never gets into the amplifier through the holes of the unit.
