FINAL SYSTEM CHECKS
1. Start the engine and turn on the source unit. After a two-second delay,
slowly increase the volume control and li ste n to the audio. If you hear
any noise, static, distortion, or no so und at all, check the connections,
and also refer to Troubl eshooting. Depending on your syste m, the levels
may be quite loud even at low volume ett in g . Until you get an "audio
feel" of the system's power, use care when adj u sting controls.
2. Vary the balance control from left to right and listen to the results. Bass
levels should not vary if the amp lifi er i configured using both Land R
audio inputs.
3. Increase the vo lume and verify that th e 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.
