Russound D850 Multi-channel amplifier (Open Box)
From the manufacturer:
Efficient High Power
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
The Russound 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
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.
