SETUP- Cooling Requirements
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.
