Rotel RMB-1585MKII Multi-Channel Power Amplifier
Incredible Power For Your Home Theatre

Rotel’s RMB-1585MKII 5-channel amplifier continues their heritage of producing high powered, perfectionist amplifiers for multi-channel systems.
Following Rotel's updated MKII design architecture, the RMB-1585MKII incorporates both circuit and component upgrades in the power supply and amplifier stages achieving ultra-low distortion, high gain amplification and signal isolation rendering multi-channel audio with ultimate precision and exacting clarity.
The Class AB RMB-1585MKII is built around two massive in-house manufactured high-current toroidal transformers designed to supply stable current to an array of 8 high-efficiency energy storage capacitors. This power supply architecture delivers rich, deep bass energy with absolute control of low frequencies even when driving the most demanding loudspeakers.
To optimise cooling, the RMB-1585MKII is equipped with 4 thermostat-controlled, variable-speed ultra-low-noise fans.
The RMB-1585MKII features a rear panel switch to select normal 5-channel mode, or Bi-Amp mode. In Bi-Amp mode, Channels 1+2 and Channels 4+5 are wired to receive the same input signal, allowing for simple bi-amplification.
This unique configuration allows the use of a separate amplifier channel for the Left and Right channel High Frequency (HF) and Low Frequency (LF) drivers, resulting in improved dynamics, and enhanced resolution from compatible loudspeakers.
The RMB-1585MKII is purpose built for Home Theatres and custom installation. Convenient auto-switching XLR Balanced and RCA inputs ensure compatibility with any AV Processor or Home Theatre receiver preamp output, and a 12 V trigger input and output provides simplified power control. Detachable rack mount hardware is available for mounting in standard 19” equipment racks.
