QSC Audio 6.0 II Troubleshooting, Amplifier won’t turn on when the Power switch is operated

TROUBLESHOOTING

The amplifier won’t turn on when the Power switch is operated-

•Verify AC power source is providing required voltage.

•Check each end of the power cord. The twist-lock or IEC-type connectors need to be properly inserted. Inspect the cord for damage. If any damage is found, replace the cord immediately.

•If using the DataPort and QSC amplifier network control applications, the amplifier could be in STANDBY mode. Check with the system operator to place the amplifiers in POWER ON mode. If required, you can check this by temporarily disconnecting the DataPort cables to each Processor; if the amplifier powers up, then the amplifier network control was forcing the amp to be in STANDBY mode.

•If using the rear panel Power Supply Control connections, be sure the control’s contacts are open.

The amplifier “cuts-out” when I really crank it up (intermittent operation)-

•Make sure the AC power source is rated for the required current! Use only 10-gauge heavy-duty extension cords.

•If the AC power source is “sagging” (or drooping) under heavy load, the circuit is overloaded or has other fundamental problems. Use another circuit or have the circuit checked by a licensed, professional electrician.

•Do not use multiple PL6.0 II’s from the same AC power circuit branch. Momentary, peak current from the AC line can easily exceed 50 Amps per amplifier. While this is well within the limits of 30 Amp (continuous) circuits, additional amplifier’s could overload one circuit branch. Always consult a licensed, professional electrician for verification of proper AC power distribution in high-power systems.

Can I use some sort of adapter on the power cord so that I can use “regular” outlets?-

•QSC Audio Products strongly discourages ANY changes in the AC power connections. Use only NEMA L5-30, 120V, 30 Ampere twist-lock connectors or the 240V cordset supplied with the amplifier. All supply circuits and AC power receptacles should be rated for voltage and current printed on the serial number plate.

•Unreliable and potentially dangerous conditions could result from using this product with improperly rated AC supply circuits. Always consult a licensed, professional electrician for verification of proper AC power distribution in high-power systems.

•In emergencies, 15A adaptors can be used if full operating levels are avoided.
