1.Cooling Plenums: Maintain a minimum 2” clearance around cooling plenums for proper amplifier cooling.

2.HP/LP/FULL Switch: Select the desired crossover setting, HP/LP/FULLfor the speaker output signal of the front channel.

3.Freq. Control: Move this detented control in a clockwise rotation to adjust the front crossover fre- quency from 30Hz to 4kHz.

4.Subsonic Filter Freq. Control: Move this detented control in a clockwise rotation to adjust the subsonic crossover frequency from 5Hz to 80Hz.

5.RCAInputs: Connect the RCAcables from the head-unit, video unit, or line driver to these RCA connectors.

6.Gain Control: Use this control to match the output level of the source unit to the input of the amplifier.

7.-12dB:For use with high level inputs (4V up to 12V). Push this switch in to attenuate the input by 12dB.

8.QBASS™ 0 to +12dB

9.Output Crossover HP/LP/FULLSwitch: Select the desired crossover setting, HP/LP/FULLfor the output signal of the RCAoutput.

10.Output Crossover Freq. Control: Move this detented control in a clockwise rotation to adjust the front crossover frequency from 30Hz to 4kHz.

11.RCAOutputs: RCAoutputs provide HP/LP/Full; 30-4KHz to another amplifier.

12.Speaker Output Connections: Plug the Speaker PowerLock™ connector in here.

5.RCAInputs: Connect the RCAcables from the head-unit, video unit, or line driver to these RCA connectors.

6.QBASS 1 & QBASS 2 Freq.: Use these switches, QBASS 1 & QBASS 2 to program the QBASS PLUS™ circuit frequency.

6.-12dB Input Attenuation: Push this switch ‘IN’ for high voltage input (4V-12V) capability. This button pushed ‘IN’ must be used for speaker level input on common ground head-units or for high voltage line drivers.

8.Freq. Control: Move this detented control in a clockwise rotation to adjust the front crossover frequency from 30Hz to 4kHz.

9.Output Crossover Control: HP/LP/FULL, Move this detented control in a clockwise rotation to adjust the front crossover frequency from 30Hz to 4kHz. (See Crossover frequency chart pg. 16)

10.Gain Control: Use this control to match the output level of the source-unit to the input of the amplifier

11.RCAOutputs: Left and right RCAoutputs provide HP/LP/Full;

30-4KHz to another amplifier.

12.Speaker Output Connections: Plug the Speaker PowerLock™ connector in here.
