Operation/Installation Manual

DESCRIPTION

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 min- imal 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.

INPUT CONNECTIONS AND AUDIO CONTROLS

The front panel of the APX280M contains both connections for RCA and speak- er level inputs, along with the audio controls as shown below.
