The RB-1090 stands as the premiere example of Rotel's award- winning prowess in amplifier design. At 9.5" tall and close to 100 lbs. in weight, it is a truly formidable power source for the most demanding systems. Essentially two separate amplifiers sharing only a chassis and power cord, the RB-1090 is capable of putting out 380 watts per channel RMS (both channels driven into 8 ohms from 20 Hz to 20 kHz with less than 0.03% THD).
Each of the RB-1090's two totally Independent power supplies is based on two large 1.25 kVA custom made, multiple-secondary toroidal ransformers and four 22,000 µf Slit Foil storage capacitors. This enormous potential feeds an output stage with four pair of power transistors, each rated at over 200 watts with more than 17 amps current capability. (Remember, these are figures for only one of the RB-1090's two channels!) The result is truly prodigious output, making the RB-1090 more than able to meet the worst speaker-induced torture tests. The RB-1090 is stable down to 2 ohms and delivers peak power in excess of 1000 watts under these demanding conditions.
But the RB-1090's real worth lies in its flexibility and sound quality. With both balanced (XLR) and single-ended (RCA) inputs and dual sets of heavy duty, "biwire-ready" 5 way binding posts, the RB-1090 easily interfaces with an encompassing range of system components. The RB-1090 also features a detachable power cord.
Sound quality, the raison d'etre for this amplifier's existence, is stunning. Authoritative bass response extends to below the limits of hearing while mid and high frequencies emerge with a supple liquidity. The result is absolutely involving. You'll literally feel the spirit of whatever source you choose.
