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 virtually any pair of loudspeakers to very 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.
