•Always wear protective eyewear when using tools.

•When routing cables, keep input signal cables away from power cables and speaker wires.

•When making connections, make sure that each connection is clean, insulated and properly secured. Observe the polarity markings on the rear panel. Refer to the application drawings to set up the amplifier for operation in stereo, bridged-mono, bi-amp or tri-mode con- figurations.

•If the amplifier’s fuse must be replaced, use only the same rating and type as a replacement. Do not substitute another kind.

Controls and Connectors

1.Pre-amp Level Input Connector – Connects to line-level output from the source unit.

2.Universal Interface Speaker Level Connector – Connects to speaker-level output from the source unit. Provides Common Sense amplifier turn-on when used with factory radios (2-channel on P-7520, 4-channel on P-7540).

3.Pre-amp Level Output Connector – Connects to other amps or processors in the signal chain.

4.Speaker-Output Connector – (2-chan- nel on P-7520, 4-channel on P-7540).

5.Fuses – P-7520: 30A ATC type, P-7540:

30A ATC type x 2, P-2510: 40A ATC type.

6.Power Connector – Connection for 12V+, Gnd and Rem.

7.Input-Mode Switch – Sums left and right inputs.

8.Input Sensitivity Control – Adjusts input sensitivity for pre-amp level and speaker-level inputs.

9.Pre-amp Output Selector Switch – Selects input path for pre-amp output. Output can be summed from front and rear inputs with no filter, or filtered by

the front or rear crossover.

10.Rear-Channel Input Selector – Selects rear-channel input between front input and rear input.

11.Crossover Selector – Determines whether the crossover is a High-Pass filter (HP), Low-Pass filter (LP) or unfiltered (flat).

12.Crossover Frequency Control – Determines the crossover frequency for the amplifier channels (front or rear) and the pre-amp outputs.
