Heatsink Cooling
The unique heatsink on
your
POWERCLASS
™
amplifier has been
designed with fins on the
inside of the aluminum
mass. This allows for the
transfer of heat from the
circuitry to the heatsink fins and out through the vents in the
endplates. Be sure you have ample space around the amplifier
for cooling, at least 2" on all sides.
THERMAL MANAGEMENT
Forced Air Thermal Management
To manage the additional heat associated with higher output
capability, a thermally controlled fan has been designed into
the
PC1800
. When the heatsink temperature reaches a
predetermined value, the fan is activated and cool air is
drawn in through the lower intake vents on the endplate.
This cool air flows below the circuit
board, through the fan and across
the internal fins, cooling the
heatsink. The warm air is
then forced out through
the upper endplate
exhaust vents.
