RB 1072

Class D Power Amplier

Rotel’s RB-1072, a 100 watt per channel stereo power amplier

is based upon the much-heralded Class D switching platforms

of the RMB-1077, RB-1092 and RB-1091 ampliers. Thanks

to its innovative design, it can be placed in space-restricted

installations without fear of performance degradation. The

RB-1072 needs little ventilation and runs relatively cool

even under demanding operating conditions, compared to

conventional amplier designs.

Although compact in size at only 2-3/8” high, there is

nothing small about this amplier. It is powerful, rened and

characterized with a sense of speed, depth and transparency

that set it apart from the competition. Rotel engineers have

methodically applied our Balanced Design Concept (BDC) to

render a very impressive design.

The RB-1072 features innovative engineering that has

transformed the sound of early Class D ampliers from less-than-

stellar products to real audiophile components. Two of these

design accomplishments are *MECC (Multivariable Enhanced

Cascade Control) and *COM (Controlled Oscillation Modulation)

which substantially reduce pulse amplitude and pulse timing

errors. Together, these technological solutions, along with Rotel’s

BDC, have helped changed the future of power amplication and

allowed Class D switching ampliers to realize their full potential

of high power, low heat, reduced chassis size, and rst class

sound.
