Features & Specs
5-channel Class AB amplification for true home-theater impact
Designed to power a full surround array with the musicality of Class AB output stages, delivering smooth detail and authority without sounding harsh at higher volumes.
High-current power that stays consistent with all channels driven
Rated at 210 W/Ch into 8Ω and 340 W/Ch into 4Ω with all five channels operating, the RMB-1585MKII is built for real-world multi-channel demands where simultaneous peaks happen constantly.
Full connectivity: balanced XLR and RCA inputs per channel
Each channel includes both XLR and RCA inputs, making it easy to match AV processors, preamps, and custom systems while reducing noise in longer cable runs when using balanced connections.
Low distortion, wide bandwidth, and quiet background for clarity
With <0.03% THD, 120 dB SNR (A-weighted), and a 10 Hz–100 kHz frequency response, it preserves micro-detail, clean dialogue intelligibility, and precise effects placement across the soundstage.
Installation-friendly control with 12V triggers and rack mounting
12V trigger in/out enables synchronized powering with your theater electronics, while rack-mount readiness (rack ears included; full kits vary by region) supports clean, professional equipment-rack builds.
Selectable Bi-Amp mode and smart cooling for reliability
A rear-panel mode switch allows standard 5-channel use or Bi-Amp routing (Channels 1+2 and 4+5 share the same input signal for simplified bi-amping), while thermostat-controlled variable-speed fans help maintain stable performance during long movies and high-output listening.

Expert Insight
Rotel provides truly expensive sound — at a bargain price. My first experience with Rotel audio equipment was in my father’s hi-fi store back in the early 80s. More than 20 years ago, I purchased my first Rotel receiver. I recently upgraded my home theater system by replacing my non-Rotel surround sound receiver with a Rotel surround sound processor and Rotel RMB-1585 MKII 5-Channel power amplifier — and the improvement was dramatic. The difference is so impactful that I actually find myself turning up the volume during commercials when the audio quality is great — something I never used to do! Rotel’s sound quality — especially their amplifiers featuring the company’s proprietary toroidal power supply — competes with high-end audio brands that cost far more.
