Owner’s Manual 3 Owner’s Manual DESCRIPTION The APX201.2 and APX401.2 use an unregulated MOSFET power supply for superior control of output wattage.
2 Channel Power System Amplifier 4 • Gain Control - This allows you to set the nominal operating level of the amplifier. The amplifier’s range, 250mV to 2.5V for RCA inputs or 500mV to 5V for speaker level inputs, can accommodate input levels from virtually any brand of source unit.
Owner’s Manual 5 CONNECTIONS FOR POWER AND SPEAKERS The rear panel of the APX201.2 and APX401.2 contains power and speaker connections as shown below. 1. Left Speaker Output 2. Right Speaker Output 3. Remote Turn-on Input 4. Ground Input 5. Battery +12V Input 6.
2 Channel Power System Amplifier 6 APPLICATIONS The Clarion APX201.2 and APX401.2 2-channel car audio amplifiers can be used in a variety of system applications. Here are some examples to help plan your own installation. Figure 3 - In this application the amplifier is bridged for mono operation to drive a subwoofer.
Owner’s Manual 7 Figure 4 - In this application, the amplifier is used in stereo and drives two full-range (or satellite or subwoofer) speakers. NOTE: A passive crossover must be used with satellite speakers.

2 Channel Power System Amplifier 12 SETTING THE GAIN After completing the installation, follow these steps to set the Gain Control and then perform the Final System Checks. 1. Turn the Gain Control all the way counter-clockwise. 2. Turn the vehicle’s Ignition Switch to the ON position.
Owner’s Manual 13 FINAL SYSTEM CHECKS 1. Start the engine and turn on the source unit. After a two-second delay, slow - ly increase the Volume Control and listen to the audio. If you hear any noise, static, distortion or no sound at all, check the connections, and also refer to Troubleshooting.
2 Channel Power System Amplifier 14 Problem Distorted audio. Solution Gain is not set properly, or damaged speaker cones. Review Setting Gain; inspect each speaker cone for signs of damage (i.e. frozen cone, burning smell, etc.) Problem Audio lacks punch.
