Refined Design for Demanding Systems
Available in black or silver, the RMB-1585MKII features a robust chassis with a clean, professional aesthetic. Its 5U rack-mountable design ensures seamless integration into AV setups, while the internal layout reflects Rotel’s commitment to performance and reliability.
Advanced Engineering for Audiophile Performance
Built on Rotel’s updated architecture, the RMB-1585MKII incorporates upgraded circuitry and components in both the power supply and amplifier stages. This results in ultra-low distortion, improved signal isolation, and efficient high-gain output across all five channels.
Powerful and Balanced Output
Each channel delivers 210 Watts into 8 ohms and an impressive 340 Watts into 4 ohms with all channels driven. This ensures consistent, dynamic performance even with demanding speaker loads—ideal for immersive surround sound and large listening environments.
Versatile Connectivity and Protection
The RMB-1585MKII includes balanced XLR and unbalanced RCA inputs, thermal and overcurrent protection, and a dual-stage power-on relay to reduce surge current. It’s engineered for longevity and reliability, making it a cornerstone of any serious multi-channel audio system.
