Rotel’s new RMB-1587MKII 7-channel amplifier furthers our heritage of producing high powered, high current, exceptionally manufactured Class AB amplifiers for multi-channel systems. The RMB-1587MKII delivers 7 channels of Class AB amplification at 155 Watts per channel into 8 ohms and drives 4 ohm speakers with over 250 Watts per channel, all channels driven.
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 significant circuit and component upgrades in both the power supply and amplifier stages achieving ultra-low distortion, signal isolation, and high-gain output power efficiently packaged in a single, multi-channel amplifier chassis.
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, and 250 Watts per channel into 4 ohms with all channels driven.
The RMB-1587MKII is available in both black and silver colors.
