RB 1072
Class D Power Amplifier
Description
Rotel’s RB-1072, a 100 watt per channel stereo power amplifier is based upon the much-heralded Class D switching platforms of the RMB-1077, RB-1092 and RB-1091 amplifiers. 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 amplifier designs.
Although compact in size at only 2-3/8” high, there is nothing small about this amplifier. It is powerful, refined 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 amplifiers from less-thanstellar 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 amplification and allowed Class D switching amplifiers to realize their full potential of high power, low heat, reduced chassis size, and first class sound.
