Rotel RMB-1585 MKII Multi Channel Power Amplifier Review: Overview

The Rotel RMB-1585 MKII Multi Channel Power Amplifier Review warmly invites audiophiles and home theatre enthusiasts to explore Rotel’s new flagship powerhouse. Boasting five channels of 200 watts each (1 kW total), this amp fuses immense firepower with Rotel’s signature Balanced Design Concept to deliver a jaw-dropping blend of dynamics, clarity and control.

Design & Build Quality

At 5U rack height and weighing in at 36 kg, the RMB-1585 MKII is no mere showpiece—it’s a precision-engineered marvel. Its robust aluminium front panel and solid steel chassis minimise mechanical resonance, while premium internal components and meticulous circuit topology ensure longevity and consistency. Whether you’re running 4 ohm floor-standers or a full Dolby Atmos array, the RMB-1585 MKII never breaks a sweat.

Technical Highlights

• Total Harmonic & Intermodulation Distortion: < 0.03%
• Frequency Response: 10 Hz–100 kHz (–1 dB)
• Damping Factor: 260
• Signal-to-Noise Ratio: 116 dB
• Input Options: Balanced (50 kΩ/3.8 V) and Unbalanced (12 kΩ/1.9 V)

These specs translate into lightning-fast transients, whisper-quiet backgrounds and effortless control over even the most demanding speaker loads.

Immersive Sonic Performance

Whether you’re watching a blockbuster or enjoying a Bach concerto, the RMB-1585 MKII excels. Explosive on-screen effects possess palpable weight, while delicate acoustic passages emerge with exquisite micro-detail. The amplifier’s broad bandwidth and ultra-low distortion ensure that every nuance—from the subtlest reverb tail to the thunderous orchestral climax—remains faithfully reproduced.

Why It Suits Serious Home Theatre Set-Ups

With five independent channels delivering identical headroom, the RMB-1585 MKII is tailor-made for immersive multi-channel systems: 5.1, 7.1 or even Atmos configurations. Its efficient 800 W consumption belies the 1 kW output capability, making it surprisingly green for such a high-powered unit. And with a minimum 4 Ω impedance rating, compatibility issues are virtually eliminated.
