Quad-channel Class-D amplifier 4 x 250W – crossover

This energy-efficient stereo amplifier will automatically switch to a standby mode when no audio signals are detected (less than 1Watt power consumption in standby mode). Their weight and compact size make these single rack space amplifiers ideal for both fixed and mobile installations. Their use of Class-D technology ensures excellent efficiency as well as outstanding sound quality. Thanks to the complete passively cooled entity only minimal maintenance is needed while ensuring maximum reliability. The quad-channel construction consists of four channels with the possibility to use two independent stereos. In combination with the integrated active crossover network, it offers a complete solution for compact stereo applications with a bass cabinet. Various specific functions and advanced circuitry guarantee optimal protection against DC malfunctioning, short circuits, overheating, and overload. Signal input connections are integrated with balanced XLR connectors. Outputs are connected using terminal block connectors.
