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