The New! PCX™ amplifiers mass has been increased by 2 lbs. per linear foot over last year’s POWERCLASS™ amplifiers, resulting in far superior heat dissipation. The unique heatsink on your PCXamplifier has been designed with fins on the inside of the aluminum extrusion. 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.

1.Cooling Plenums: Maintain a minimum 2” clearance around cooling plenums for proper amplifier cooling.

2.QBASS™ Control: Add more bass to the system by turning this control clock - wise to boost the selected QBASS™ frequency up to 18dB.

3.QBASS™ Remote Port: Port to plug in the optional QBASS Plus™ Remote knob.

4.Power & Ground Connections: After connecting the power and ground cables to the PowerLock™ wire connector, plug it in here.

5.Power Indicator: A green light indicates that the amplifier power is ON.

To manage the additional heat associated with higher output capability, a thermally controlled fan has been designed into the PCX 280. When the heatsink temperature reaches a pre-determined 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.
