High efficient power

More powerful, more efficient, more robust... simply more. For nearly 50 years, Russound has been designing equipment to meet the needs of installers. When we went to redesign the next generation of our ubiquitous line of multi-channel amplifiers, we approached it from the ground up. The result is the D Series, a completely customized solution that has all the great features of our popular R Series amplifiers in a much more refined platform.

The Russound D850 digital multi-channel amplifier delivers the features custom installation professionals demand while offering a lighter weight, smaller chassis, and more efficient Class D power. The D850's feature-rich design 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 discrete amplification and customized settings for each of the 4 zones.

Sound quality

All D-Series amplifiers feature the same legendary Russound sound quality and easy-to-install features customers have come to expect. Ultra-low distortion output (relatively unheard of in other multi-zone amplifiers) allows for clean, distortion-free 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 amplifiers are even up to the rigorous demands of home theater applications, easily transforming into a powerful 160 watt X 4 channel monster (in bridge mode). You can also choose to unpair pairs individually for lower power applications, such as Dolby Atmos® or surround speakers. As an example, you could run a 5.1 system with 3 channels at 160W and 2 channels at 50W. That's the versatility of Russound!

Say "no" to the buzzing

Advanced trigger options allow amplifiers to operate on demand. Aside from the obvious energy efficiency, there is no amplifier hum in the speakers when the system is not in use.
