SETUP- Cooling Requirements

Cooling Air Inlet and Exhaust Vents

The PL6.0 II has four rear-mounted variable- speed fans. Fan speed is determined by the temperature of the amplifier’s internal heatsink assembly.

Cooling air is drawn into the rear of the amplifier by the fans and exhausts through the front panel. The temperature of the air exiting the front vents is a good indicator of how hard the amplifier is working.

If mounting in a rackmount enclosure, be certain not to restrict the ability of fresh cooling air to enter back and exit the front. Do not use in enclosures with closed or sealed backs or fronts.

The amplifier relies on free air flow in and out of its vents. Keep the vents free of obstructions and dust buildup. Periodic inspection of the vents for dust buildup is recommended. If required, use a small bristle-brush gently around the vent openings while the amplifier is running. Do this outside to avoid blowing dust onto other equip- ment.

Be certain not to obstruct or block the cooling air vents in any way! Loss of cooling air flow could result in the amplifier 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 produce heat.
