FINAL SYSTEM CHECKS
1. Start the engine and turn on the source unit. After a short two-second delay,
slowly raise the volume and listen to the sound. If you hear any noise, static,
distortion, or no sound at all, check the connections, and also refer to the
"Troubleshooting" section. Depending on your system design, the levels may
become quite loud even a low volume control settings. Until you get a "feel" of
the power of the system, use care when adjusting the controls.
3. Increase the volume and verify that the APA4400G/APA4200G amplifier repro¬
duces audio without distortion at all frequencies. If you hear distortion, check the
connections and verify that the gain controls are set correctly. Another possibility
is damaged (or under-powered) speakers. Once again, refer to the
"Troubleshooting" section for additional help.
2. Adjust the balance control from left to right and listen to the results. Audio imag¬
ing should match control settings.
