The pinnacle of performance in Rotel’s superb multichannel power amplifier range, the RMB-1585 features 5 x 200 Watts to drive even the largest of home theatre speaker systems.


Key Features

  • 5 x 200 Watts of robust power into 8 ohms
  • Class AB amplifier design
  • High-quality slit foil capacitors made in Britain
  • Balanced XLR inputs
  • Two pair of 5-way speaker binding posts
  • 12-volt trigger control

The RMB-1585, Rotel’s new flagship theater amplifier, provides both the massive power and sonic sophistication required by the finest home theater systems. With five channels, each capable of producing 200 continuous Watts each into 8 ohm loads (a full kilowatt of output power!), the RMB-1585 masters any A/V system regardless of speaker load or room size.

But it isn’t just pure output power that distinguishes the Rotel RMB-1585. It’s the ability to reproduce both the dynamics of a Hollywood blockbuster and the musical nuances of acoustic instruments that sets it apart. Where does this balance come from? It’s a direct result of Rotel’s celebrated Balanced Design Concept in which circuit topology and parts selection meld in the pursuit of sonic excellence.

The power supply of RMB-1585’s output section benefits from eight British-made BHC Slit Foil caps, each with a capacity of 15,000 µF. And each channel uses six individual power transistors to ensure stable power delivery to all speakers in the system even under the most demanding conditions. Dual fans provide more-than-adequate airflow for proper thermal dissipation.

These and other high quality components were carefully chosen for their significant contribution to better sound quality and then “tuned” to each other for even further aural improvements.

The RMB-1585 makes system connection easy with both single-ended inputs via RCA jacks or balanced connections via three-pin XLR connectors.

In summary, you could describe the RMB-1585 as a “brute” that provides a full kilowatt of power. Or you might regard it as an exacting conveyer of the most subtle aspects of music or a movie soundtrack. In either case, you’d be correct. You’d also be correct if you simply said that the RMB-1585 is the win-win answer for everyone seeking authoritative yet nuanced control of the speaker array of your choice.
