Efficient High Power Sound From An 8-Channel Amplifier

Get powerful and more efficient audio with the Russound Digital Amplifier, 8-Channel. With similar features of the Russound R-Series Amplifiers, the D series can be completely customized to provide ultra-low distortion output that produces clean, undistorted audio, even when listening at high levels. It's built with a lightweight, smaller chassis, and features a robust protection circuit that helps protect the output channel of each amplifier, all while providing safe and efficient operation under extreme conditions. The D850 is compatible with Russound volume controls and designed for the demands of distributed audio systems because of its 8 channels that are arranged in stereo pairs, which provide discrete amplification and customization for configuring each 4 zones.

  • 8-channel amplifier arranged in stereo pairs for custom configurations for each 4 zones
  • 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms
  • Zones can be bridged for creating flexible power configurations
  • Compatible with Russound volume controls
  • Global and independent zone triggering
  • Signal sensing turns on amp when signal from sources is sensed
  • Can be rack mounted using the included rack-mount ears and hardware

The Russound D850 Amplifier is extremely versatile. In bridge mode, it can provide a 160 watt x 4 channel high powered zone that meets the rigorous demands of a home theater application or you can individually un-bridge pairs to run lower applications using surround speakers. Additionally, you won't hear amplifier hum from the speakers when the system isn't in use since the D850 offers advanced triggering options, which allow the amplifier to operate on demand.
