Rotel RMB-1506 6-Channel Amplifier

Rotel RMB-1506 6-Channel Custom Installation Amplifier

Power multiple rooms with confidence using the Rotel RMB-1506, a rugged 6-channel Class AB power amplifier built for clean, dependable multi-zone audio. Delivering 6 x 50 watts per channel into 8 ohms (or 6 x 80 watts per channel into 4 ohms), it’s an ideal solution for distributing music to up to three stereo zones when paired with a surround receiver or a preamp/processor. Custom-install friendly features like automatic signal sensing, 12V trigger input, front-panel level (attenuation) controls, and input linking make it easy to integrate into racks, cabinets, and whole-house systems. A buffered link output lets you expand your system by daisy-chaining additional amplifiers for larger installations, while five-way binding posts and an IEC detachable power cord keep connectivity professional and serviceable.

The Rotel RMB-1506 is part of ListenUp's Rotel Power Amplifiers Collection.

What It's Good At:

• Driving up to 3 stereo zones (6 channels) for whole-home audio and distributed music
• Delivering robust Class AB power with low distortion for smooth, detailed sound
• Custom-install integration with 12V trigger and automatic signal sensing (auto turn-on)
• Rack-friendly setup with included rack ears and 3U front-panel height
• Scaling multi-zone systems using input linking and a buffered link output
• Dialing in each area with front-panel attenuation controls for zone-by-zone level matching
