Diagnostic Aids
- Incorrect speaker mounting or loose trim may cause an audible buzz or distortion.
- The EL-50334-6 Audio System Diagnostic CD contains audio tracks that can be used to duplicate and isolate concerns. Tracks 11 and 12 contain audio sweep tones for testing for speaker and grill rattles. The test tones on the CD may be copied to a USB drive or other device to use during testing.
- Some circuits supply audio signals to more than one speaker. It may be necessary to disconnect all speakers on the affected audio circuit when performing circuit tests.
