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. They are mounted within the back portion of the enclosure. The amplifi- ers rely upon an unobstructed air flow in and out of the respective vents, shown below. Keep these air vents free of obstructions and dust buildup. 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.
