CONNECTIONS- AC Power

AC Power Connection

The 215PCM requires a 120 Volt, 30 Amp connection to the AC mains. The power connectors used are to be NEMA L5-30, or equivalent. The serial number plate is imprinted with the operating voltage informa- tion.

At peak output power, the 215PCM can supply up to 6,600 watts of music power. At these levels, the AC line current can easily reach levels in excess of 20 Amps. Proper AC connections are required at such high power levels.

Connect the 30 Amp twist-lock connectors by orienting the locking L- shaped prong with the corresponding connector entry, then fully insert the three prongs. Twist the plug about 1/8 of a turn clockwise to lock the connector and plug.

The 215PCM requires 120 Volt, 30 Amp AC service. Attempting full power operation on lower rated circuits may overheat wirirng and cause breakers to switch off.

Use only heavy-duty 12 or 10 ga. extension cords.

AC Power Switch

Above and to the right of the AC entry connector is the Power switch. The switch is labeled POWER ON, above it.

To turn the power on: Press in on the upper portion of the rocker switch. Both DSP-3’s blue Power indicators should illuminate.

To turn the power off: Press in on the bottom portion of the rocker switch. It may take a few moments for the Power LED’s to extinguish. This is normal.
