Multichannel power amplifiers put great demands on the critical power supply stage of a conventional Class AB amplifier. The power supply must be designed to deliver sufficient voltage and current to all channels; at all times, even if that means simultaneous pyrotechnic explosions in all channels! Some manufacturers don't design for this eventuality, and consequently do not reproduce complete audio performance without harshness or strain.
That's why Rotel manufactures their own transformers to strict specifications in their own facility. They understand the importance this critical circuitry has on total performance. That's the key reason that Rotel Multichannel amplifiers deliver their rated output into ALL channels!
Rotel RMB-1575 Multi Amplifier
5 Channel Power Amplifier
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. It is important to note that this specification is provided with "all channels driven at 8 ohms" unlike some other manufacturers who stretch the ratings by listing them at 6 ohms or with only one or two channels being driven. 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-1075 runs relatively cool, extending the components lifespan thanks to its innovative Class D design.

Rotel RMB-1565 Multi Amplifier
5 Channel Power Amplifier
The RMB-1565 is designed around the same superb Class D design as the RMB-1575 but with a slightly smaller output of 5 x 100 Watts per channel into 8 ohms. It is the perfect choice for medium to large home theater rooms. Plus, just like its bigger brother, it will double its output with more difficult lower impedance loads, thereby providing 5 x 200 Watts into 4 ohms. It also includes all of the custom installation features such as 12 volt triggers, and "U height" dimensions that are demanded of today's modern power amplifiers.
