Hi,
I am not familiar with audio design.
My designed module has a classic circuit for MIC +- input, as the attachment Our1.jpg.
The other side is another vendor, which has a classic mic circuits as Other1.jpg.
The problem is when Other1.jpg P and N linked to Our1.jpg MICP and MICN,
the user can hear big noise and the voice is not clear.
What's the issue?
Is it the matching issue? If I link a 1.2K resistor between MICP and MICN, can this issue be solved?
Many thanks.
Best,
Tony LIU
