FINAL SYSTEM CHECK
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 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. Once again refer to
Troubleshooting for additional help.
