I have a class AB 4ohm amp- under specifications it says input sensitivity 0.1~1v impedance 10Kohm, under level adj it says the input range is 150millivolts to 5volts and the sensitivity is adjustable from 3 volts min to 200 millivolts max. Can this be translated to a range signal level the amps input can acept with its adj and is it rms or max peak. Also how could I work out the amps output voltage it is 60 watts rms / 300 watts max power and will be connected to a 4ohm load (toroidal transformer). Gary
