News Rotel Unveils Compact Seven-Channel Power Amp (26/9/2005) Intelligent digital power supply, unique circuit topology packs 700 watts in 1U rack form factor The latest power amplifier from Rotel, globally accepted leader in value-high-end components for uncompromised audio and hometheater systems, breaks new ground for space-saving efficiency and innovative design. The new RMB-1077 power amp boasts a super-slim, rack-mount component just over 2-inches tall, while delivering no less than 700 watts-seven fully independent channels of 100W each. This unprecedented combination lends the new Rotel unbeatable appeal for high-performance, seven-channel power in custom-installation home theaters, or wherever super efficient, ultracompact, multi-channel power is required. "With the RMB-1077 we're looking at the future of audio amplifiers," says Rotel America VP and General Manager Mike Bartlett. "Digital technologies and 'smart' power-supply design have finally evolved to the point where they can yield an amplifier that rivals and even outpaces the performance of traditional, brute-force, 'copper-and-capacitors' designs." Key to the remarkable new RMB-1077's design are two proprietary technologies. Rotel's Controlled Oscillation Modulation (COM) underpins entirely new levels of efficiency, stability, and effectiveness from a switching-type digital power supply, while Rotel's, Multivariable Enhanced Cascade Control (MECC) circuit topology creates a "smart" amplifier in which the power supply and the actual amplifying circuits work cooperatively to boost efficiency to a most impressive 90%. The result is a seven-channel, 2-1/2" tall power amplifier that is far less massive than many two-channel preamplifiers, yet offers a stable, dynamic, musical, full-bandwidth 100W from each channel. The RMB-1077 is ideal for all home-theater configurations and with 12-volt trigger facilities for automated system integration and a detachable IECstandard power cord, the RMB-1077 integrates easily into any system.
