APX280M APX490M manual.qxd 2/6/2008 11:38 AM Page 3 Operation/Installation Manual DESCRIPTION The APX290M and APX490M use 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 compo- nents keeps AM RFI subdued. All of the connections and controls for the APX290M and APX490M are conv

When creating passage holes for power cables, RCA's cables, and speaker wires, use grommets to eliminate any sharp edges created during drilling. This will protect the wire from being nicked and causing a short circuit. 8. Extra cable can cause signal loss and act as an "antenna" for noise. Use only high-quality RCA cables that are no longer than necessary. 9. In multiple amplifier systems
