DESCRIPTION

The Clarion APX401.4 4-channel car audio amplifier is an excellent choice for creating a variety of multi-channel sound systems. The amplifier features flexi- bility of 2, 3 or 4 channel system by a flip of a switch. You can also configure the front or rear amplifier sections for a mixed mode operation to drive a set of satellite speakers and/or subwoofer.

The built-in 12 dB per octave electronic crossover lets you custom tailor the sound of the front and rear channels, using two independent filters with adjustable crossover frequencies for high-pass or low-pass filtering.

The amplifier also uses an unregulated MOSFET power supply for superior control of output wattage. A toroid-coil transformer yields maximum power transfer with minimal heat loss. Extensive circuit design keeps AM RFI at low levels, so you won’t hear unwanted noise when the level is cranked up. Protection circuits safeguard the amplifier when overheating, speaker shorts, or improper load conditions occur.

All connections and controls are on the end panels and are easy to under- stand. Gold-plated RCA and barrier connectors are used to ensure the best electrical connection for your system. Integrated into the endpanel is an external automotive fuse that is easy to replace.
