Rotel RMB-1587 MKII Multi-Channel Power Amplifier

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 colours.
