7100 Audio IN

[chet david]

When audio records on my 7100, it is imbalanced always. It records right volume extremely loudly and left audio very quietly. I have checked that the problem is not with cable or device being recorded from.

Sound Control Panel settings?

Are you certain that the jack is making it deep enough into the sound in port? Some jacks are more obstructive than others. Have you verified by recording with a different computer?

 

[chet david]

Yes, other computer works fine. All settings seem correct.

It MIGHT be a bad capacitor. The thought of a bad cap on a Power Mac logic board sends shivers up my spine. I suppose the 7100 is 16 years old or so, they're bound to start dropping soon. xx(

Not only are the 7100s over 16 years old now, they also were made during the Spindler era, when the cheapest components in Mac history were used. It doesn't surprise me in the least that these caps would fail.

I've heard of iMac G3s with failing caps (maximum age = 12), so anything is possible!

It seems that the problem comes and goes.

Does it come and go when you wiggle the connector? That would indicate either the socket pins are bent inside or a bad solder joint.

Does it come and go depending on how long the machine has been on? That would indicate a bad solder joint that expands and makes better contact once the machine has heated up.
