The Rotel RMB-1587 MKII is a high-current, seven-channel power amplifier designed for home theatre systems that require consistent, full-range performance across every channel. Built as part of Rotel’s MKII platform, it incorporates updated circuitry and component refinements to improve efficiency, reduce distortion, and maintain stability under demanding multi-channel loads.
Each of the seven channels delivers 155 watts into 8 ohms, with the ability to drive 4-ohm speakers at over 250 watts per channel—all channels driven. This consistent power delivery is a key part of the design, ensuring that performance does not drop off when multiple channels are active simultaneously—an important factor for modern surround and immersive audio systems.
The amplifier is built around a substantial power supply featuring dual in-house manufactured toroidal transformers and high-capacity storage capacitors. This architecture provides stable current delivery across all channels, supporting dynamic peaks and maintaining control in complex passages. The internal layout is optimized for signal isolation and low noise, following Rotel’s Balanced Design Concept.
Connectivity is designed for straightforward system integration. The RMB-1587 MKII includes auto-sensing balanced XLR and single-ended RCA inputs, allowing it to work seamlessly with a wide range of AV processors and preamplifiers. A 12V trigger input and output enable synchronized power control, while the inclusion of rack ears and a 5U chassis height make it suitable for custom installations.
Thermal management is handled by a set of thermostat-controlled, low-noise cooling fans, ensuring reliable operation even in enclosed racks or high-demand environments. The overall construction is substantial, with a high-mass chassis designed to minimize vibration and maintain long-term durability.
