B 1 IMPORTANT SAFETY PRECAUTIONS & EXPLANATION OF SYMBOLS 1- Read these instructions. 8- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9- Do not defeat the safety purpose of the grounding-type twist-lock NEMA L5-30 AC power connections. The polarized, locking plug has one blade that is shaped differently than the others. [. . . ] CH2's output is also wired to the upper Speakon's 2+ and 2- terminals for biamp applications. Do not use the lower speakon if using the upper Speakon in biamp connection. Each Speakon has a wiring chart (pinout) printed next to it for easy reference. The pin numbers (1+, 1-, etc. . . ) correspond to the pin numbers marked on the Speakon. When the Speakon locks into place, an audible "click" confirms connection. To connect a Speakon, insert the keyed plug into the receptacle and twist counterclockwise to lock in place. Speakons provide a clean appearance, reliable electrical connection and positive locking mechanism. To remove a Speakon, pull the thumb-latch back and twist counterclockwise 1/8th turn. 18 USE- Cooling Air Inlet and Exhaust Vents Cooling Air Inlet and Exhaust Vents Be certain not to obstruct or block the Cooling Air Vents in any way!Loss of cooling air flow could result in the amplifiers going into thermal shutdown (protective muting to help cool the amplifier and prevent damage). Keep the vents free of dust and dirt buildup as airflow will be reduced. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that product heat. The 215PCM contains two forced-air cooled QSC Powerlight 2-series amplifiers. The amplifiers rely upon an unobstructed air flow in and out of the respective vents, shown below. Be certain not to block the vents in applications where the 215PCM might be covered with textile curtains or located close to walls. Cooling air is pulled into the center air intake vent by both amplifiers. The air is pulled through each amp and exhausts from each end of the rear panel. The temperature of the air exiting theses vents is a good indicator of "how hard" the amplifier is working. 19 USE- AC Power Switch and LED Indicators 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 after a brief amplifier startup sequene. To turn the power off: Press in on the bottom portion of the rocker switch. This is normal. Power switch. LED Indicators Each Processor has two LED indicators, PWR and SIGNAL. PWR- When the 215PCM is connected to a properly rated and working AC supply circuit and is turned on, the blue PWR LED on each of the Processors will illuminate. When the system is powered up correctly, two blue Power LED's will be visible; one on the Top Box Processor and one on the Subwoofer processor. SIGNAL- The SIGNAL LED indicates input signal presence and strength. 20 LED indicators. USE- LED Indicators (continued) and Important User Caution LED Indicators (continued) NOTE!If both PWR indicator LED's fail to illuminate after turning the power to the 215PCM on, verify the AC power is working and is properly connected. If this fails to correct the problem, disconnect the DataPort connections (if any) and retry. If the PWR indicator illuminates now, the DataPort was forcing the amplifier into Standby mode.
