A six-channel power amplifier for multizone systems. Rotel rates the RMB-1506 at 50 W per channel into 8 ohms with all channels driven, and describes it as a rugged amplifier for systems with a limited number of zones.

THIS IS AN OPEN BOX PRODUCT AND MAY HAVE SOME COSMETIC BLEMISHES, PHOTOS COMING SOON, HOWEVER WE WILL SEND PHOTOS TO YOU BEFORE SHIPPING TO CONFIRM WITH YOU. Standard warranty applies

Rotel pairs the RMB-1506 with a Rotel surround receiver or preamp/processor to add music to three additional zones. Six channels means three stereo zones. A buffered link output lets you connect more amplifiers for larger multizone systems.

Channels

6 (three stereo zones)

Power (8 ohms)

50 W per channel, all channels driven

Power (4 ohms)

80 W per channel, all channels driven

Design

Class AB

Trigger

12 V trigger input

Size (W x H x D)

431 x 144 x 424 mm

Why you will love it

Six channels of Class AB power

Rotel rates the RMB-1506 at 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms, with all channels driven. Total harmonic distortion is listed as below 0.03% from 20Hz to 20kHz.

It is a Class AB design. Rotel lists a damping factor above 200 and a minimum speaker impedance of 4 ohms.

Built for multizone and custom installs

Rotel lists the RMB-1506 with a front panel attenuation control, input linking, a 12-volt trigger, a buffered link output, five-way binding posts and a detachable IEC power cord.

It also has automatic signal sensing. Rotel says you can add another RMB-1506 for larger multizone systems through the buffered link output.

Is it right for you?

A great fit if you…

Want to add music to up to three extra zones from a surround receiver or preamp/processor
Need an amplifier with a 12-volt trigger and automatic signal sensing for a custom install
Plan to link a second amplifier for more zones

Worth knowing

This is an open box product; please read the condition note at the top of this page
The RMB-1506 is a power amplifier with no volume control of its own beyond the front panel attenuation, so it needs a preamp, receiver or processor ahead of it
Rotel specifies a minimum speaker impedance of 4 ohms
The 50 W and 80 W ratings are per channel with all channels driven

Build your system

The RMB-1506 takes a line-level signal from a receiver or preamp/processor and powers three stereo zones.

Source: Browse AV receivers or the Rotel range for a unit to feed the amplifier.
Speakers: Add in-ceiling speakers or bookshelf speakers in each zone. Check each speaker is at least 4 ohms.
Alternatives: For a single room, see stereo amplifiers.
