The 9BSST2 is a modular design 5 x 120 Watts 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 9BSST2 may be controlled by a remote control voltage . The 9BSST2 includes 'soft start' power control circuitry to eliminate high inrush currents when AC power is applied .
