More power, more efficient, more robust-¦just more. For nearly 50 years Russound has been designing equipment to fit an installer's needs. When we went to redesign the next generation of our ubiquitous multi-channel amplifier line, we approached it from the ground-up. The result is the D-Series, a completely custom-built solution that has all the great features of our popular R-Series amps in a much more refined platform.

The Rossound D850 digital multi-channel 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.

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.

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!

Advanced triggering options allow the amps to operate on demand. Apart from the obvious energy efficiency, there is no amplifier hum on your speakers when the system isn't in use.
