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.
