The 6BSST2 is a modular design 3 x 300W per channel audio power amplifier. Each channel selects a balanced or single ended input. Each channel selects a gain of 29dB(1v), 23dB(2v) or 17dB(4v). Each channel input may be operated inverted or non-inverted operation (0 or -180 degrees). The power up of the 6BSST may be controlled by remote control voltage. The 6BSST2 includes 'soft start' power control circuitry to eliminate high inrush currents when A/C power is applied.
