Rotel RMB-1587 MKII Multi-Channel Power Amplifier

ROTEL RMB-1587MKII Multi-Channel Power Amplifier

....with 7 Channels of Breathtakingly Beautiful POWER!

Rotel’s new RMB-1587MKII 7-channel amplifier continues its heritage of producing high powered, perfectionist amplifiers for multi-channel systems.

Following the 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 two highly-efficient, in-house manufactured toroidal transformers in the Class AB RMB-1587MKII deliver a steady current to 8 high-capacity energy storage capacitors.

This powerful arrangement produces vigorous low-end bass tones, accurately driving even the most challenging audio components with uncompromising precision.
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.

Massively engineered, this 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 optimise cooling, the RMB-1587MKII is equipped with four 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 Theatre 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.
