The front panel handles are reversible, allowing for easy grip or flush rack mount installation. The PS3 includes rear support brackets for mobile applications. Each PS model shares the same attractive appearance, with a different color accent on its nameplate for easy model identification. The entire heat sink assembly can be replaced in minutes allowing quick service, if required. Dual speed forced air cooling is employed in all Perfomance Series amplifiers.
Cool air is drawn in through the slots in the front of the chassis.
In the all Performance Series models, the fan forces the incoming cool air into the center of the heat sink fins. The heat is forced out the sides and back of the chassis. The large heavy fins on Performance Series heat sinks do not require filters, eliminating frequent filter service required in other designs. On the higher-powered PS3, a switchable clipping eliminator is included. This advanced optocoupled circuit provides up to 20dB of limiting to keep upstream errors and overambitious operators from damaging precious speaker systems.
