The Rotel RMB-1585MKII stands as the flagship multichannel amplifier in Rotel’s portfolio, designed to deliver uncompromising performance for high-end home theater systems and demanding multichannel setups. With an optimized Class AB architecture, oversized power supply, and premium-grade components, this 5-channel power amplifier guarantees a highly dynamic, accurate, and controlled audio reproduction in even the largest listening environments.
Exceptional Power, Absolute Control
The RMB-1585MKII delivers an impressive 210 watts per channel into 8 ohms, or 340 watts per channel into 4 ohms, with all five channels driven. For systems requiring even more dynamic headroom, the amplifier can reach 440 watts per channel at 4 ohms with just two channels active—showcasing its immense power reserves and stable load handling.
Despite its brute strength, the RMB-1585MKII maintains ultra-low distortion and surgical precision across the frequency range, allowing every cinematic detail, musical nuance, and explosive sound effect to be conveyed with clarity and emotion.
Redesigned Internals for Superior Performance
The MKII revision features a completely reengineered internal layout, including:
Dual Rotel-made toroidal transformers for a stable and isolated power supply.
High-grade slit-foil capacitors selected for fast transient response and authoritative bass.
Refined circuit topology ensuring superior channel separation, reduced noise floor, and enhanced linearity.
All of this is enclosed in a robust steel chassis with included rack ears for professional or custom installation.
