The Denon DN-A850 is a professional-grade, multi-zone commercial mixing amplifier designed for fixed background music and zone-paging installations in venues like restaurants, hotels, clubs, and bars. Engineered as a robust 3U rack-height chassis, this heavy-duty unit combines a 4-channel audio mixer with a 4-channel monaural power amplifier, providing flexible, independent multi-room routing from a centralized location. Built with high-quality components in Japan, it is highly regarded by commercial AV integrators and audio enthusiasts for its longevity, tactile control design, and clean, analog sound reproduction.
Key Features
4-Channel Independent Routing: Integrates a 4-channel mixer with a 4-channel power amplifier, letting users distribute unique sound sources across four isolated acoustic spaces or zones.
Dedicated Power Output: Generates a stable 50 Watts per channel into 4 Ohms across all four channels simultaneously, ideal for distributed commercial loudspeaker networks.
Dual Microphone Support: Equipped with 2 dedicated mic inputs accepting balanced XLR and standard 1/4-inch phono jacks for localized announcements or corporate paging.
Centralized Audio Priority: Features dedicated "Page All" and "Page Zone" routing switches with a built-in -30 dB background music override (ducking) system.
System Expandability: Includes dedicated Preout jacks for every single zone, allowing integrators to daisy-chain the mix into supplementary power amplifiers to scale up larger venues.
Commercial Reliability: Enclosed in a rugged 3U rack-mountable housing featuring protective terminal covers and high-visibility input signal LED indicators.
