TOP PANEL CONTROLS

1.Input Gain Adjustment - Controls amplifier sensitivity and is used to match the input level of the amplifier 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.Output Crossover Frequency Adjust- ment - Adjusts the crossover point for the on-board active crossover for the 1-4 OUT RCA jacks.

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

5.Variable Bass EQ - Adds 0 to12db of additional boost to channels five and six output when active.

6.Input Parallel Switch - Controls the input signal to the indicated channels. If the 3+4 switch is ON, channels 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. If the 5+6 switch is ON, channels five and six will derive their signals from chan- nels one through four RCA jacks and no input is needed. If the 5+6 switch is OFF, channels five and six RCA jacks must have input.
