Product Description 

Larger listening environments require prodigious amounts of power to deliver room filling sound. That’s exactly what you get with Rotel’s 5 x 250 Watt power amplifier. Rotel’s RMB-1575 is a true high current audiophile design and can double its output to 5 x 500 Watts at 4 ohms with all channels driven.

Pure muscle alone, however, does not make a superb amplifier. The RMB-1575 excels at extracting all of the smallest audio details from both music and movie soundtracks alike. Best of all, even with its high power capability the RMB-1575 runs relatively cool, extending the components lifespan thanks to its innovative Class D design.
