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

RB 1072
Class D Power Amplier
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.
