Rotel RMB-1587MKII Multi-Channel Power Amplifier

Following Rotel's MKII design architecture, the RMB-1587MKII incorporates both circuit and component upgrades in the power supply and amplifier stages to achieving ultra-low distortion, signal isolation, and high-gain output power efficiently packaged in a single, multi-channel amplifier chassis.

The Class AB RMB-1587MKII is engineered around two massive in-house manufactured high-current, low emission toroidal transformers designed to supply stable current to an array of 8 high-efficiency bulk storage capacitors. This power supply architecture renders deep bass energy even when driving the most demanding loudspeakers with ultimate authority and control.

Differing from multi-channel amplifiers whose output drops when driving multiple channels simultaneously, the RMB-1587MKII delivers all 7 channels of Class AB amplification at 155 Watts per channel into 8 ohms. This massively engineered amplifier achieves 250 Watts per channel into 4 ohms with all channels driven and is capable of a staggering 335 Watts RMS per channel when used in Stereo into 4 ohm loudspeakers.

To optimize cooling, the RMB-1587MKII is equipped with 4 thermostat-controlled, variable-speed ultra-low-noise fans.

The RMB-1587MKII is built for custom installation. Convenient auto-switching XLR Balanced and RCA inputs ensuring compatibility with any AV Processor or Home Theater receiver preamp output, and a 12 V trigger input and output allows simplified power control. Custom rack mount installation hardware is available for simplified mounting in standard 19” equipment racks.(1)

The RMB-1587MKII is available in both elegant black and stylish silver colors.

Features

• Class AB Power Amplification
  The RMB-1587MKII utilizes 7 independent Class AB amplifiers allowing each channel to drive at full rated output power, all channels driven simultaneously. When higher power is required for any channel, the amplifier will automatically route up to 335 watts of power to that channel with premium audio performance.
• Dual High Current Toroidal Transformers
  Two in-house manufactured oversized low noise toroidal transformer delivers high efficiency ultra-stable power to critical amplifier circuits lowering the noise floor and reducing distortion.
• Customizable Input and Output Options
  The RMB-1587MKII supports both XLR Balanced and RCA inputs ensuring compatibility with all popular home theater systems. The unit automatically detects and switches to the attached connection ensuring ultimate installation simplicity. 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-1587MKII 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.
• Rack Mount Installation
  Rack mounting kits are available to ensure the RMB-1587MKII comfortably fits both on the shelf or mounted in a standard 19” equipment rack. The custom engineered rack mount kits ensure and durable support for this 83 pound (37kg) prodigious amplifier.
