DESCRIPTION
The Clarion APX400.4M 4-channel marine amplifier is an excellent choice for creating a variety of multi-channel sound systems. It features built-in system design flexibility that allows you to create a 2, 3 or 4 channel amplifier with 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 12dB 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 minimum heat loss. Careful 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 against overheating, speaker shorts, or improper load conditions that may occur.
All connections and controls are on the end panels and are easy to understand. We use gold-plated RCA and barrier connectors to ensure the best electrical connection for your system. Included are external automotive type fuses that are easy to replace.
