DESCRIPTION: 
The 4BSST2 is a dual mono design audio power amplifier with two channels of each. Each channel has switch selectable balanced and single ended inputs. Each channel also has switch selectable gains of 29dB(1v) or 23dB(2v). The 4BSST2 includes SoftStart power control circuitry to eliminate high inrush currents when A/C power is applied. The power-up or turn-on of the 4BSST2 may be activated by the push-button power switch on the front panel or via hard wired remote control voltage.
