Rated 4.9 (120 reviews)
The Ecler AURA-4B150 is a four-channel Class D installation amplifier giving 150W per channel into 8, 4 or 2 ohms or onto 70V and 100V lines. Pairs of channels can also be bridged for 300W. The 1U chassis is shallower than the higher-power AURA models and can be rack or desk mounted, which suits smaller multi-zone systems in bars, restaurants, hotels, retail, gyms and schools and offices.
