TROUBLESHOOTING
The 215PCM “cuts-out” when I really crank it up (intermittent operation)-
• Make sure the AC power source is rated for 120V, 30 Amps. Do not use 20 or 15 Amp AC supply circuits for the
215PCM! Use only 12 or 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 fundamen-
tal problems. Use another circuit or have the circuit checked by a licensed, professional electrician.
• Do not use multiple 215PCM’s from the same AC power circuit branch. Momentary, peak current from the AC line
can easily exceed 50 Amps per 215PCM. While this is well within the limits of 30 Amp (continuous) circuits, additional
215PCM’s could overload one circuit branch. Always consult a licenced, 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. All supply circuits and AC power receptacles should be rated for 120 V., 30
Amp service.
• 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.
How can I adjust the gain settings on the amplifiers? Any recommended tool for the job?-
• See page 10 for details.
• Two recommended tools: Excelite #R186 (metal, 6” blade screwdriver) or GC Electronics #8988 (fiberglass, 12”
blade adjustment tool).
The 215PCM 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 connectors need to be fully inserted and twist-locked into place.
• If using the DataPort inputs 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 215PCM powers up, then the amplifier network
control was forcing the amps to be in STANDBY mode.
• Inspect the AC power cord for damage. Unplug from the AC power source and then carefully inspect the cord for
damage. Replace if any damage is detected.
