AURA-2B900

Name: Ecler AURA-2B900
Brand: Ecler
SKU: AURA-2B900

Two channels amplifier | 2x900 W RMS @ 4Ω | LoZ&HiZ | Class D

AURA-2B900 is two channels, 2x900 W RMS @4Ω, high efficiency amplifier (class D). Compatibility with both Low and Hi impedance configurations and supporting dual or bridge mode (@4/8Ω). AURA Series are built with the highest robustness for long lasting performances with special power supply circuitry designed for optimized electrical consumption with fan cooling system. AURA Series also features the possibility of linking channels to the first input by selecting it on the rear panel, as well as auto stand-by, overload and thermal protection, PFC and anti-clipping system. The front panel volume knobs can be locked using rear panel switches for added security.
