DESCRIPTION

The APX480M 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 APX480M 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. An additional benefit of this amplifier is the ability to create a 2, 3, or 4 channel amplified system with a flip of a switch (see Application section). In the event of component failure or a short circuit, the APX480M incorporates safe guards and an outboard ATC fuse to prevent damage to the amplifier

INPUT CONNECTIONS AND AUDIO CONTROLs

The front panel of the APX480M contains both connections for RCA and speaker level inputs, along with the audio controls as shown below.
