Speaker/Grill Rattle Test (50 Hz to 8 Khz Swept Sine)

The next portion of the tape can be used to diagnose speaker and grill rattles. The first test is two tones played back-to-back. The second test is a variable frequency tone, but frequency change is at a much slower rate. Both tests can be used to repair a speaker rattle or buzz. If the problem has already been isolated, the fade and balance controls can be set to the proper location and test tones can be played in the specific problem area.
