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

2.Rear Speaker Connector: Plug in the PowerLockTM connector here.

3.Front Speaker/Remote Connector: Plug in the PowerLockTM connector here.

4.QBASSTM Level Control: Controls bass boost, centered at 40Hz with up to 18dB of boost.

5.-12dB Attenuation Switch: Push this switch ‘IN’ for high voltage input (4V-12V) capability. This button must be pushed ‘IN’ for use with speaker level input on common ground head-units or for high voltage line drivers.

6.RCA Output: RCA outputs provide HP/LP/FULL 30-4kHz signal to another amplifier.

7.Rear Inputs: Plug in the rear RCA leads from your source here.

8.Front Inputs: Plug in the front RCA leads from your source here.

9.Front Gain: Use this control to match the output level of the source unit to the front channel of the amplifier.

10.Front Freq. Control: Move this detented control in a clockwise direction to adjust the front crossover frequency from 30Hz to4 kHz. (see Crossover Frequency chart in this manual).

11.Front HP/LP/FULL Switch: Select the desired crossover setting. HP/LP/FULL for the speaker output signal of the front channel.

12.Rear Input INT/EXT Switch: Select the INT position if you want
