Features & Specs
True 7-channel Class AB power for serious theaters
Class AB topology delivers strong dynamics and refined detail, ideal for immersive surround formats and demanding speaker arrays.
Consistent output with all channels driven
Engineered to avoid the power “drop-off” common in multichannel amps, maintaining impact and clarity across every channel during peak scenes.
Massive high-current power supply architecture
Dual toroidal transformers and high-quality slit-foil capacitors help deliver stable current for deeper bass authority and improved control into real-world speaker loads.
Low distortion, wide bandwidth performance
Ultra-low THD and an extended frequency response help preserve detail, separation, and natural tonality from subtle ambience to explosive transients.
Installer-friendly connectivity and integration
Auto-switching XLR balanced and RCA inputs make it easy to pair with AV processors and receivers while supporting noise-resistant balanced runs.
Custom-install ready chassis features
12V trigger in/out simplifies automation, thermostat-controlled variable-speed fans support reliable operation, and included rack ears help streamline rack mounting.

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 RMB1585 MKII 5-Channel power amplifier (had my speaker system required more power, I would have gone with the Rotel RMB-1587 MK II) but 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.

Rotel RMB-1587MKII Power Amplifier
The Rotel RMB-1587MKII is a high-current, 7-channel Class AB power amplifier built to bring true theater-grade dynamics and control to premium home theater and custom-install systems. Unlike many multichannel amps that sag when all channels are working, the RMB-1587MKII is engineered to deliver consistent, full-bandwidth power across every channel—driving demanding speakers with authority, clarity, and tight bass grip.
At the heart of the design is Rotel’s MKII architecture with meaningful circuit and component upgrades, anchored by a massive power supply with dual toroidal transformers and high-quality slit-foil capacitors for stable current delivery and low noise. Add in balanced XLR and RCA connectivity, 12V trigger control, thermostat-controlled variable-speed cooling, and included rack ears, and you have a powerhouse amplifier that fits cleanly into serious home theater racks and high-performance media rooms. Available in black or silver.
It’s a high-current, 7-channel Class AB power amplifier built to power premium home theater and custom-install multichannel speaker systems with stable, consistent output.
How much power does it deliver with all channels driven?
It delivers 155 W per channel into 8 ohms and 250 W per channel into 4 ohms with all 7 channels driven, helping maintain dynamics during demanding scenes.
Does it support balanced connections from an AV processor?
Yes—there are XLR balanced inputs as well as RCA unbalanced inputs, providing flexible integration with AV processors and receivers.
Can it handle difficult speaker loads?
Yes. The amplifier’s high-current design and strong power supply help it control and drive demanding speakers, including 4-ohm loads, with authority.
Is it suitable for rack installation?
Yes. Rack ears are included, and the chassis/front panel height is designed to fit standard equipment racks for clean custom installs.
Does it include trigger control for system automation?
Yes. It includes 12V trigger input and output, allowing your processor or control system to power the amplifier on/off automatically.
How does it manage heat in a multi-channel setup?
It uses thermostat-controlled, variable-speed ultra-low-noise fans to optimize cooling while keeping operational noise low.
What finishes are available?
The RMB-1587MKII is available in black or silver to match common AV rack and component aesthetics.
