Product Description

The Russound D-Series amplifiers available in 8 and 16 channel versions.  Through redesign the digital amplifiers now feature 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

Russounds D850 amplifier features 8 channels / 4 zones.  This means you can run 4 pairs of stereo speakers into 4 independent rooms or zones each pair producing 100W. All rooms can 4 independent music sources at any time or any zone can be joined to the internal Bus to play the same music in all zones. With 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.

Need more Power?

With Bridgable Channels, the D850 can increase the power output from the amplifier to your speakers. By bridging the channels you will decrease your zone / room availability but increase the power to the speakers working from the bridged channel.The D-Series amps are even up to the rigorous demands of home theatre 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 at 50W. That’s Russound versatility!

What is Class D

Class D is digital amplification, cool running amplification, light weight smaller chassis,high efficiency (> 90% on average);which is significantly better than a Class-AB design (78.5 percent at best and typically closer to 50 percent).

Lose the “hum”

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.
