TOP PANEL CONTROLS

1.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.

2.Crossover Selection Switch - Controls the type of filter for the on- board active crossovers. 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 typically used for subwoofers.

3.Crossover Frequency Adjustment - Adjusts the crossover point for the on board active crossovers.

4.Bass EQ Switch - Adds an additional 8 db of boost to the speaker output when on.
