Rotel RMB-1585MKII Multi-Channel Power Amplifier

Rotel’s new RMB-1585MKII 5-channel amplifier continues our 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 optimize 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 Theaters and custom installation. Convenient auto-switching XLR Balanced and RCA inputs ensure compatibility with any AV Processor or Home Theater 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.(1)

The RMB-1585MKII is available in both elegant black and stylish silver colors.

Features

• Class AB Power Amplification
  The RMB-1585MKII features 5 independent Class AB amplifiers allowing each channel to drive at full rated output power, all channels driven simultaneously. When higher output power is required for any individual channel, the amplifier will instantly and automatically route up to 440 watts of power to that channel with premium audio performance.
• Dual High Current Toroidal Transformers
  Two in-house manufactured toroidal transformer delivers high efficiency, low noise, ultra-stable power with reduced electromagnetic interference to critical amplifier circuits lowering the noise floor and reducing distortion.
• Customizable Input and Output Options
  The RMB-1585MKII supports both XLR Balanced and RCA inputs automatically detecting and switching to the attached cabling method ensuring ultimate installation flexibility. Sturdy 5-way speaker binding posts support up to #10AWG (2.58mm) wire ensuring secure connections with minimal signal loss for optimal audio performance.
• Exceptional Build Quality and Reliability
  Globally respected for over 60-years, Rotel is recognized as an industry leader for robust build quality and reliability. The RMB-1585MKII follows this proud tradition manufactured by our in-house skilled technicians using high-quality components assembled in a sturdy chassis.
• Advanced Thermal Management
  High precision sensors monitor internal temperatures activating advanced thermal management systems to regulate the temperature utilizing CPU controlled, variable speed, low noise cooling fans.
• Bi-Amp Configuring Delivers Higher Power Outputs
  User selectable Bi-Amp mode allows the RMB-1585MKII to operate as a 3-Channel amplifier which is most effective driving the Front Right, Front Left and Center channels (LCR Amplifier). When Bi-Amp mode is enabled, the amplifier powers 2 amplifier channels for the Left and 2 for the Right channels separating the High Frequency and Low Frequency amplification and cabling for an even higher level of efficiency and output drive to the speakers.
