TOP PANEL CONTROLS

1.Input Gain Adjustments - Control amplifier sensitivity and are 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 used for subwoofers.

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

4.Sub Phase Switch - Changes the phase of the subwoofer speaker output by 180 degrees

5.Variable Bass EQ - Controls up to 12 dB bass boost to the subwoofer output.

6.Sub Input Switch - Controls where the subwoofer section of the ampli- fier gets its signal. If the SUB INPUT switch is in the ON position the subwoofer section of the amplifier will get its signal internally summed from the channels one through four RCA jacks, and the SUB RCA jacks do not need input. If in the OFF position the SUB RCA jacks must have input.

7.Input Parallel Switch - Controls the input signal to the indicated chan- nels. If the 3+4 switch is ON, chan- nels three and four will derive their signal from channels one and two RCA jacks and no input is needed. If the 3+4 switch is OFF, channels three and four RCA jacks must have input.
