Clarion APA5241 User Manual

OPERATION/INSTALLATION MANUAL
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, since the inputs are internally summed.
NOTE: When using 2-channel inputs, set the amplifier’s front/rear
balance via the GAIN CHI/2 and GAIN CH3/4 controls.
3. Increase the volume and verify that the amplifier reproduces audio
without distortion. If you hear distortion, check the connections and
verify that the amplifier gain and BASS EXTENDER controls are set
correctly. Another possibility is damaged (or under-powered) speakers.
Once again, refer to Troubleshooting for additional help.
