Macintosh Performa 6200: Can't Record from 1710AV Display

TECHINFO-0019714

TOPIC

I am having difficulty using the built-in microphone of the AppleVision 1710AV Display with my Macintosh Performa 6200CD. Whenever I attempt to record sounds with this setup, the recording appears muffled and contains a lot of static. However, if I connect the PlainTalk microphone directly into the computer, I get clear sound recordings. What could be causing this to happen?

DISCUSSION

Apple is aware of this issue and is investigating it. It does not appear to be an issue with the AppleVision 1710AV Display. Rather, it appears that this issue can occur on all computers with a this form factor, including the Macintosh 630, 6200, and 6300 series computers.

Currently, the only workaround is to use the PlainTalk microphone connected directly to the computer's microphone port.

Note: The following computers are in the corresponding Macintosh families:

• Macintosh 630CD family: LC 630, Quadra 630, Performa 630, Performa 631, Performa 635, Performa 636, Performa 637, Performa 638, and Performa 640.

• Macintosh 6200CD family: Performa 6200, Performa 6214, Performa 6216, Performa 6218, Performa 6220, and Performa 6230.

• Macintosh 6300CD family: Performa 6300, Performa 6290
