Operation/Installation Manual
FINAL SYSTEM CHECK
1.
Start the engine and turn on the source unit. After atwo-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 lowVolume Control settings. Until you get an
"audio feel"
of
the system1s power, use care when adjusting controls.
2.
Turn the Balance Controls to their extreme positions and listen to the
results. Audio output 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. Ifyou 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.
