Clarion APX400.2M Stereo Amplifier User Manual


 
DESCRIPTION
The Clarion APX400.2M two-channel amplifier provides 2x70 watts of power
into a 4 ohm load and 2x110 watts of power into a 2 ohm load. This full
featured model is an excellent choice for a variety of marine audio sound
system configurations.
The APX400.2M 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 attention to 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 and speaker
shorts or improper load conditions occur.
All connections and controls of the APX400.2M 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 is an external
automotive type fuse that is easy to replace.
