Rotel RMB-1587MKII. 7-Channel High-Fidelity Power Amplifier for Premium Home Theater Systems
The Rotel RMB-1587MKII stands at the pinnacle of high-performance multichannel amplification. Purpose-built to drive the most ambitious next-generation home theater systems, this amplifier delivers stunning sonic impact, tonal balance, and precise dynamic control—without compromise.
Equipped with seven channels of robust Class AB amplification, the RMB-1587MKII delivers a consistent 155 watts per channel at 8 ohms and 250 watts per channel at 4 ohms with all channels driven. Whether for immersive cinema or multichannel music, this amplifier ensures unwavering power and control—even in the most demanding passages of a movie soundtrack.
True Continuous Power, Engineered for Audiophile Fidelity
Unlike many multichannel amplifiers that throttle output under full load, the RMB-1587MKII maintains full rated power across all seven channels—thanks to its enhanced MKII architecture featuring:
Dual oversized toroidal transformers—custom-built in-house by Rotel for ultra-stable power delivery.
High-efficiency slit-foil capacitors for fast current response and deep, authoritative bass.
Refined circuitry for reduced crosstalk, lower distortion, and enhanced thermal efficiency.
All this is housed in a robust, rack-mountable steel chassis, making it suitable for professional installations and premium home environments alike.
