The heat sink allows the amplifiers to operate at a cooler temperature and prevents overheating, which helps
the longevity of the entire system. The heat sink has hollow fins, which help dissipate the heat from the
amplifiers faster than a conventional serrated or corrugated fin.
In addition to the cooling effects of the heat sink, within each 500-watt power amplifier enclosure, there are
four fans that each provide 170 cubic feet per minute (CFM) of air flow (into zero static pressure). There are
two fans mounted at the front of the heat sink and two mounted at the back end of the heat sink operated in
a push-pull configuration to assist with heat dissipation. The fans are a 24Vdc variety, so there are series
dropping resistors to drop the higher power supply voltage down to a safe level.
