OPERATION/INSTALLATION MANUAL
DESCRIPTION
The Clarion APA5241 5-channel car audio amplifier (shown in Figure 1)
has a unique circuit topology that provides an additional summed output (on
channel 5) to drive one or two subwoofers. The built-in mode switch
provides convenient design flexibility so you can quickly configure a 3-, 4-,
or 5-channel system with a flip of a switch. For 4-ohm loads, the APA5241
delivers 35 watts of continous (rms) power on channels 1 through 4 and
100 watts of continous (rms) power on channel 5.

The built-in 12 dB-per-octave electronic high-pass/low-pass crossovers let
you tailor the sound of all channels with selectable frequencies at 80,120,
or 180 Hz. Alternately, channels 1 through 4 can be set to pass all
frequencies with channel 5 configured for low-pass filtering. With this
built-in feature you don't need to add external crossovers and cables,
resulting in a cost-effective, efficient way to implement your design ideas.
The APA5241 uses a regulated MOSFET power supply for superior
control of output wattage, regardless of input voltage or musical energy
content. MOSFETs are chosen for their inherent characteristics to provide
superior accuracy, stability, and control. A toroid-coil transformer yields
maximum power transfer with minimum heat loss. Careful attention to
