Professional 4-channel power amplifier in an extremely compact 19" 1U-housing (H: 44mm) The high efficient class-D design guarantees high power and very low heat dissipation. Perfect for install applications (pubs, shops, hotels, restaurants, … ) The unit houses 2 separate class-D amplifiers that can be configured independently to obtain the following combinations: Both amps in stereo mode: 4x 150Wrms @ 4Ω (4x 80Wrms @ 8Ω) Both amps in Bridge mode: 2x 300Wrms @ 8Ω 1amp in stereo + one amp in bridge: 2x 150Wrms @ 4Ω + 1x 300Wrms @ 8Ω Completely silent operation: NO cooling fans! Peak limiter prevents signal distortion DC fault + high temperature + overload + short circuit protections Balanced Combo (XLR + jack) inputs. Speakon® + bind-post wire terminal outputs
