About this item
Written by Crutchfield's Dave Bar
Powerful, cool-running multichannel power amp
Russound's D850 amplifier offers versatile multi-room flexibility and plenty of power when and where you need it for top-notch sound. Enjoy clear stereo sound in four rooms, or combine two channels into one to give your speakers more juice — a great option for power-hungry outdoor speakers. And unlike traditional amps that run hot and waste a lot of energy, the D850 boasts a high-efficiency Class D amplifier design for cool operation, reduced weight, and clean, undistorted sound even at high listening volumes.
More flexible options for enjoying music throughout your home
The D850 can distribute music from one audio source, such as a networked music streamer, to multiple rooms in your home. Or you can connect up to four separate sources and play a different one in each listening room. Each of the amplifier's playback "zones" features independent left- and right-channel gain controls so you can adjust its output to fine-tune the levels of each speaker in your system. For music playback in more than four rooms, you can daisy-chain multiple Russound amplifiers together.
