Power Amplifier Four Zone/Eight-Channel (D850) – Russound

Description

Power Amplifier Four Zone/Eight-Channel (D850) – Russound

The Russound D850 digital multi-channel Power Amplifier offers the features custom installation professionals demand while offering a lighter weight, smaller chassis and more efficient Class D power. The feature-rich design of the D850 is ideal for the demands of distributed audio systems and is also compatible with our Russound volume controls. Its 8 channels are arranged in stereo pairs to provide discreet amplification and custom configurations for each of 4 zones.

Sound Quality

The D-Series amplifiers all have the same legendary Russound sound quality and installer-friendly features customers have come to expect. Ultra-low distortion output (relatively unheard of in other multi-zone amplifiers) allows for clean, undistorted audio even at high listening volumes. A robust protection circuit provides efficient, safe and reliable operation under extreme conditions and protects each amplifier output channel.

Home Theater

The D-Series amps are even up to the rigorous demands of home theater applications, easily transforming into a powerful 160 watt X 4 channel monster (in bridged mode). You can also choose to individually un-bridge pairs for lower power applications such as Dolby Atmos® or surround speakers. As an example you could run a 5.1 system at 3 channels @ 160W and 2 channels @ 50W. That’s Russound versatility!
