Troubleshooting

Adjusting Crossover Input Gains:

1.Adjust all crossover gain controls to 0 dB, 1/2 of maximum sensitivity.

2.Adjust all amplifier gains to 1/2 of maximum sensitivity.

3.Turn the volume knob on the equalizer to a maximum of 3 o'clock.

4.Increase the gain of the crossover until the onset of audible distortion. Then decrease the gain prior to the immediate point of audible distortion. This setting will minimize system background noise and prevents overloading of the crossover.

5.Repeat step 4 for any remaining crossovers in the system.

6.Adjust the input gains next.

NOTE: In many multi-crossover / accessory systems, the gain of some crossover and accessories may need to be further decreased to achieve proportional balance.

Adjusting the Amplifier's input Gain:

Adjust the amplifier's input gain to 1/2 maximum sensitivity. Turn the volume knob on the equalizer to a maximum of 3 o'clock. Increase the gain (clockwise) until the onset of audible distortion. Then decrease the gain counterclockwise prior to the immediate point of audible distortion. This setting will minimize system background noise and prevents overloading of the amplifier. Repeat step 3 for any remaining amplifiers in the system.

NOTE: Depending on the sensitivity of the systems preamp(s), the gain of the amplifier(s) may not need adjustments. Also, in many multi-amplifier systems, the gain of some amplifiers may need to be further decreased to achieve proportional balance.

If for some reason your system fails to operate properly, please refer to this guide. If you are unable to resolve the problem, consult your Authorized PPI Dealer or call 1-800-62-POWER.

NO SOUND

Is the power LED illuminated?

Check fuses in power wire.

Be sure turn-on lead is connected.

NO SOUND IN ONE CHANNEL

Check speaker leads and inspect for a short to ground or an open connection.

Check pre-amp leads. Reverse left and right leads to see if the problem is before the amplifier.

Check Mono Bridge and Bi-Amp crossover switches on other units prior to the amp.

If the problem is in the amp, have your Dealer inspect the unit.

AMP TURNING OFF

Is the amp able to cool properly?

Check speakers for shorts or damage.

Make sure power and ground are secure.

Have PPI Dealer inspect amp.
