Owner and Service Manual Review

The Clarion APX280M is a full-featured two-channel power amplifier. The APX280M uses an unregulated MOSFET power supply for superior sound and output wattage. In addition, a toroid-coil is used to transfer power with minimal performance loss due to heat. To avoid unwanted noise, a double-sided conformal printed circuit board with strategically placed components keeps AM RFI subdued.

All of the connections and controls for the APX280M are conveniently located at the ends of the amplifier and labeled appropriately. To ensure the best possible electrical connections, the power, speaker, and RCA inputs are gold-plated. In the event of component failure or a short circuit, the APX280M incorporates safe guards and an outboard ATC fuse to prevent damage to the amplifier.
