Russound D850 8-Channel Digital Amplifier with Independent Zones

Optimize distributed audio and security monitoring with the Russound D850 8-channel digital amplifier. Built for installers and systems integrators, this Russound amplifier combines Class-D efficiency with robust multi-zone control to deliver clean, reliable audio for commercial, retail and surveillance environments. The D850 provides 640W RMS total output across eight discrete channels—arranged for four independent zones or bridged for higher-power zones—while 12 audio inputs and per-zone trigger/audio-sensing auto-switching simplify integration with access control, intercom and monitoring systems. Its compact, rack-mountable design reduces rack space and heat, and the rugged protection circuitry keeps critical systems online under demanding conditions. Whether you’re specifying audio for a security operations center, retail store, or multi-room office, the D850 balances power, flexibility and efficiency so integrators can deploy consistent, low-maintenance audio for security, surveillance and paging applications. Backed by a 2-year limited warranty, the D850 is ready to be specified into your next distributed audio or monitoring project—contact us to configure a system.
