Amplifier and crossover controls

1.2ch/4ch input switch- Leave this switch OUT if you are using 4 channels of input. Push the switch IN if you have only 2 channels of input to send input 1 and 2 to channels 3 and 4, respectively. (see page 15)

2.5/6 source- This switch selects the source for channel 5 and 6. Select the input source as input RCA 1 and 2, the summed signals from RCA inputs 1and 3 and 2 and 4, or as RCA inputs 5 and 6.

3.level controls- Use these controls to match the input level from the source unit to each pair of amplifier channels. (see page 15)

4.crossover 1/2 switch- this switch will turn the channel 1/2 crossover on or off, or send channel 3 and 4 signal to channels 1 and 2, respectively. (see page16)

5.crossover 1/2 frequency- This control sets the highpass crossover point for channels 1 and 2. (see page 16)

6.crossover 3/4 highpass switch- Push this switch IN to activate the channel 3/4 highpass crossover, or OUT to bypass the crossover. (see page 16)

7.crossover 3/4 highpass frequency- This control sets the highpass crossover point for channels 3 and 4. (see page 16)

8.crossover 3/4 lowpass switch- Push this switch IN to activate the channel 3/4 lowpass crossover, or OUT to bypass the crossover. (see page 16)

9.crossover 3/4 lowpass frequency- This control sets the lowpass crossover point for channels 3 and 4. (see page 16)

10.crossover 5/6 switch - This switch will turn the channel 5/6 crossover on or off, or send channel 3and 4 signal to channels 5and 6, respectively (see page 16)

11.crossover 5/6 frequency this control sets the lowpass crossover point for channels 5 and 6 (see page 16)

12.output switches- These switches determine whether the output is mono, bridged or stereo configuration for channels 1/2 and 3/4. (see page 15)

13.Constant Bass level- Use these controls to mix summed mono sub-bass information into channels 1/2 and 3/4. (see page 17)

14.Constant Bass frequency- This control sets the lowpass crossover point of the Constant Bass signal. (see page 17)

15.AC502 control- When using an optional AC502 remote level control, the AC502 will control the constant bass level when the switch is IN, or channel3/4 level when the switch is OUT. (see page 17)
