RMB-1587 MKII
Power Amplifier
Premium Design for Demanding Systems
The RMB-1587MKII reflects Rotel’s commitment to quality and performance. Available in black or silver, its robust chassis is built to handle the demands of high-end AV installations, combining elegant styling with durable construction.
Consistent Power Across All Channels
Unlike typical multi-channel amplifiers, the RMB-1587MKII delivers full output across all seven channels—155W into 8 ohms and 250W into 4 ohms. This ensures consistent, dynamic performance for immersive home cinema and multi-room audio setups.
MKII Architecture for Enhanced Fidelity
Featuring upgraded circuitry and components in both the power supply and amplifier stages, the RMB-1587MKII achieves ultra-low distortion, improved signal isolation, and efficient high-gain output. It’s engineered to deliver clean, precise sound with exceptional clarity.
