Diagnostics CD 07AAZ-SDBA100
Individual Speaker Test
Do this test to identify a faulty speaker.
1. Insert the audio diagnostic CD (T/N 07AAZ-
SDBA100) into the audio unit.
2. Play track No. 30 (steady 300 Hz tone) at a normal,
or slightly higher than normal, volume level.
3. Listen to each speaker for poor sound compared to
the other channels. Use the audio unit's fader and
balance settings to help isolate the channel with the
problem.
• If the sound quality produced by a specific
speaker is poor, substitute it with a known-good
speaker. If the poor sound quality continues, go
to the sound balance test (see page 23-105).
• If the sound quality is OK, go to the sound
balance test (see page 23-105).
