The amplifier features flexibility of 2, 3 or 4 channel system by 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 12 dB 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. [. . . ] Note the filter settings. 8 Owner's Manual 2-Channel High Power System (Satellite or Subwoofer) Figure 6 - The APX401. 4 can be set up as a 2-channel high-power amplifier to drive a pair of satellites (or subwoofers). 9 4 Channel Power System Amplifier Mixed-Mode System On Rear; Full-Range Speakers On Front FREQ (hz) 80 100 125 150 200 L( H m) 8. 0 6. 4 5. 1 4. 2 3. 2 C(uF) 497 398 NOTE: Chart values based on 4 ohm speakers. Figure 7 - The amplifier can be configured for a mixed-mode operation on either channels 1/2 or 3/4 amplifier sections. The table provides component values to create a 6dB per octave crossover at specified frequencies. Use components that have a + 5% tolerance and capacitors rated at 100V. Do not overlap frequencies, as this may damage the amplifier. 10 Owner's Manual INSTALLATION This section lists Mounting and Wiring Precautions prior to installing the Clarion APX401. 4. These safeguards provide enough detail to complete an installation successfully. If you do not have the necessary skills, do not attempt to install the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations. MOUNTING PRECAUTIONS Although the Clarion APX401. 4 incorporates heat sinks and protection circuits, mounting the amplifier in a tight space without any air movement can still damage internal circuitry over time. Choose a site that provides adequate ventilation around the amplifier. For easy system set-up, mount the amplifier so the front panel controls can be accessible after installation. For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Do not install the amplifier on plastic or other combustible materials. Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, brake lines (under chassis), or electrical wiring. If you are not sure of the connections, contact your authorized Clarion dealer. Before installation, make sure the source unit Power switch is in the OFF position. Disconnect the negative (-) lead of the battery before making any power connections. When making connections, be sure that each connection is clean and secure. A secure, clean ground connection is critical to the performance of your Clarion amplifier. Use the shortest ground wire possible and securely connect to the car chassis to minimize resistance and avoid noise problems. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the vehicle's (+) battery terminal. Use a fuse rated to the total current consumption of the amplifier(s).
