Clarion APX400.2 Power Supply User Manual


 
DESCRIPTION
The Clarion APX200.2 and APX400.2 two-channel amplifiers provide 2x70
watts and 2x110 watts of power into a 4 ohm load and 2x110 watts and 2x190
watts of power into a 2 ohm load. These full featured models are an excellent
choice for a variety of car audio sound system configurations.
The APX200.2 and APX400.2 use 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 APX200.2 and APX400.2 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.
