Phase Test

Do this test to confirm proper speaker phasing.

1. Insert the audio Diagnostic CD (07AAZ-SDBA100) into the CD player unit, the DVD player unit, or the BD player unit.

2. Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.

3. The voice should sound centered and focused when it indicates it is in-phase.

4. The voice should sound diffused, and have less bass when it indicates it is out of phase.

• If the voice changes from in-phase to out of phase as indicated by the prompt, the phasing is correct. Go to Electrical Noise Test.
• If the voice always sounds out of phase, phasing is not correct. Check for:
• • Shorted speaker wire
  • Open in speaker wire
  • Shorted speaker
  • Loose connection or poor pin fit
  • Faulty audio unit or audio-navigation unit
  • Faulty CD player unit, the DVD player unit, or the BD player unit
  • Faulty stereo amplifier
  • Aftermarket audio components like amplifiers, speakers, etc.
