Resumen del manual
This will protect the wire from being nicked and causing a short circuit. ♦ Extra cable can cause signal loss and act as an “antenna” for noise. Use only high-quality RCA cables that are no longer than necessary to make a direct connection with the source unit or equalizer. ♦ Depending on the type of system being installed, refer to the examples in Figures 4 through 6 (starting on page 6) for information on wiring and setting the operation mode.

Use this chart to find a copper-wire gauge that will exhibit no more than a 0.5 volt drop for a desired cable length. If aluminum or tinned wire is used, select an even larger gauge size to compensate for material difference. NOTE: Cable-size calculations take into account terminal connection resistance. SETTING GAIN After completing the installation, follow these steps to set the amplifier’s GAIN control: 1. Turn GAIN and BASS extender controls fall left to minimum positions. 2. Turn the vehicle’s ignition switch to the ON position. Thai turn on the source unit Set all tone or equalization controls to “flat” positions and tum loudness off. 3. Play a CD or tape and set the volume control at 75% of full level. 4. Verify that the POWER indicator on the amplifier comes on. NOTE: When using an equalizer, set its frequency controls to“flat.” 5. If appropriate, set the fader control (on the source unit) to feed the amplifier at full level. Slowly increase the GAIN. Stop when you hear a slight distortion of audio. 12 ♦ Setting Gain OPERATION/INSTALLATION MANUAL USING THE HP/UP FILTER NOTE: Clarion recommends turning the amplifier off before changing any switch position to eliminate any possible damage from transient spikes to the amplifier or speaker system. 1. Depending on your application, slide the FILTER/BASS EXTENDER switch to HP (high-pass) or LP (low-pass). NOTE: If your application does not require a high-pass or low-pass filter, slide the FILTER/BASS EXTENDER switch to BASS and turn the BASS EXTENDER control full left to 0 dB. 2. Set the FREQ control set to the recommended crossover point from the speaker manufacturer. 3. Listen to a variety of music styles (Rock, Rap, etc.) and slightly increase or decrease the FREQ control until the best performance is realized. USING THE BASS EXTENDER NOTE: Clarion recommends turning the amplifier off before changing any switch position to eliminate any possible damage from transient spikes to the amplifier or speaker system. 1. Slide the FILTER/BASS EXTENDER switch to BASS. Initially set the FREQ control full right to 200 Hz and turn the BASS EXTENDER gain control to its middle position (i.e., +6 dB). 2. Listen to a variety of music styles (e.g., Rock, Rap, etc.) and slowly decrease the FREQ control until no noticeable increase in low bass response is perceived. 3. Slowly adjust the BASS EXTENDER gain control (up or down) to realize the best bass response. CAUTION: If you hear a “pop” (due to speaker over-excursion), lower BASS EXTENDER gain or raise FREQ to prevent speaker damage. If the system sounds muddy and distorted (due to amplifier clipping), lower BASS EXTENDER gain to avoid shutdown from overheating or raise FREQ until clear bass response returns. Using The HP/LP Filter & Bass Extender ♦ 13 Clarion APA2102 FINAL SYSTEM CHECKS 1. Start the engine and turn on the source unit. After a two-second delay, slowly 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. Depending on your system, the levels may be quite loud even at low volume settings. Until you get an “audio feel” of the system’s power, use care when adjusting controls. 2. Vary the balance control from left to right and listen to the results. Bass levels should not vary if the amplifier is configured using both L and R audio inputs. 3. Increase the volume and verify that the amplifier reproduces audio without distortion. If you hear distortion, check the connections and verify that the GAIN and BASS EXTENDER controls are set correctly. Another possibility is damaged (or under-powered) speakers. Once again, refer to Troubleshooting for additional help.
