RMB-1077 Class D Seven Channel Amplifier

Class D amplifiers are not new. But, to date, many Class D

amplifiers have been relegated to low performance electron-

ics, or limited bandwidth products such as subwoofers. Now,

with ICEpower® technology, Rotel’s new RMB-1077, delivers

full bandwidth, high performance sound with plenty of power

output and ver y low heat and distortion.

The new Class D technology is based on two principals named

Controlled Oscillation Modulation (COM) and Multivariable

Enhanced Cascade Control (MECC). Together, these two

designs form the intelligent power processing (the brains)

of the technology to ensure that the amplifier’s power supply

and output is rock solid even under complex speaker loads

or power supply variations.

The result is a high power, high performance, multichannel

power amplifier that occupies only 2.5” of height; a minimal

amount of space compared to regular amplifiers for heat

dissipation. That’s because the RMB-1077 Class D amplifier

is over 90% efficient and produces almost no heat.

The RMB-1077 of fers up a lot of power in a small package.

At 7 x 100 watts per channel into 8 ohms, it is a superb

choice for all but the ver y largest home theater systems.

RB-1091 Class D Mono Amplifier

This incredible new Class D amplifier from Rotel is based upon

the same ICEpower® technology as utilized in the RMB-1077.

The principal dif ference between the two being that RB-1091

produces a prodigious 500 watts mono into 8 ohms from

a 3⁵⁄₈” high chassis. Rotel’s new Class D amplifiers are incred-

ibly power ful and stable and will provide increasing amounts

of voltage and current down to 4 ohm loads.

RB-1092 Class D Stereo Amplifier

The RB-1092 is the stereo version of the RB-1091 Class D

amplifier. It can generate up to 2 x 500 watts into an 8 ohm

load and can drive vir tually any pair of loudspeakers to ver y

loud sound pressure levels when required. When combined

with an RB-1091 and another RB-1092 for a five-channel home

theater system, the sonic result is absolutely breathtaking.

“there is simply no other multi-

channel power amplifier avail-

able that’s this compact, elegant

in appearance and cool headed

in operation”.

“whether it’s grappling with the

rebel camp firelight in Predator

or slicing its way through the

classic freeway chase from The

Matrix Reloaded this amplifier

delivers a thunderous sound

with no hint of hardness, stress

or strain”.
