Page 6: Other Features
OTHER FEATURES AUTO ON/OFF This amplifier features an automatic on/off circuit that allows the user to set up once and forget it. With the power switch in the “AUTO” position, a switching circuit consisting of U1D, U5A, & U5B, senses an input signal. From this switching circuit, JFET Q100 on the power amp board is biased OFF which removes the grounding of the signal. -
