Final System Check; Troubleshooting - Clarion XN3210 Owner's Manual & Installation Manual

FINAL SYSTEM CHECK

1. 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 refer to the Troubleshooting section.
Depending on your system design, the levels may become quite loud even at
low Volume Control settings. Until you get an "audio feel" of the system's power,
use care when adjusting controls.
2. Turn the Balance Controls to their extreme positions and listen to the results.
Audio imaging should match control settings (audio from the left speaker when
balance is left).
3. Increase the volume and verify that the amplifier reproduces audio (at full
frequencies) without distortion. If you hear distortion, check the connections and
verify that the Gain Control is set correctly. Another possibility is damaged
speakers or under-powered speakers. Refer to the Troubleshooting section for
additional help.
