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

The next portion of the tape may be used in order to diagnose the following conditions:
^ Speaker rattles
^ Grille rattles

The first test is 2 tones played back to back. The second test is a variable frequency tone. The frequency change is at a much slower rate. You may use both tests in order to repair a speaker rattle or buzz. If the problem has already been isolated, the fade and the balance controls may be set to the proper location and the test tones may be played in the specific problem area.
