3.Input Gain Adjustment - Controls amplifier sensitivity and is used to match the input level of the ampli- fier to the output level of the signal source.

4.Crossover Selection Switch - Controls the type of filter for the on- board active crossover. FLAT does not attenuate any frequencies and is for full-range speaker systems. HPF attenuates low frequencies and

is used for mid-range speakers and tweeters. LPF attenuates high frequencies and is used for subwoofer speakers.
