This well-made power amplifier offers flexible installation options for home theater or multi-room sound systems.

A versatile power amplifier

Rotel’s RMB-1504 delivers 70 watts of clean, robust power per channel to all of its four channels. It’s a great choice for driving your overhead speakers in a Dolby Atmos® surround sound setup, or serving as part of a multi-room custom installation.

Convenient connections and switching

There are two pairs of binding posts on the back panel for connecting two pairs of speakers, with switches that allow you to link the inputs or use them independently. A stereo RCA output link lets you daisy-chain an additional amplifier. Three selectable turn-on options (front panel switch, 12-volt trigger control, or signal-sensing) let you further adapt the amp’s performance to your needs. Rack mounting ears are included.
