Are you sure this isn’t just a bad seal?
No bad seal!
If I connect the microphone directly to the iPad everything works.

I have no idea why that would be the case. What type of mic/adc do you use?
I use an Umik-1 with its built in USB adc and I don’t have such problems.
An China 711 with 3,5 jack. I have ordert an external USB soundcard.
I think I once read that the internal MacBook sound cards have pop protection on the microphone. But I can no longer find the article.

Hi, I now have my measurement microphone with 711 and am trying to measure my IEMs with REW on my MacBook Pro.
Now I have the problem that the MacBook behaves strangely because the low frequencies are not displayed correctly. All IEMs look the same at the bottom. On my iPad the microphone works without any problem. Is there a setting on the Mac that I can't find for the 3.5mm TRRS connector?6E11749B-E5C6-44E5-BEEC-5B41F09E736A.jpeg



it is as if the software was set to 200hz, check this

No need for external soundcard, use apple 3.5mm dongle, super accurate
Hello,
Thanks to everyone who helped me!
The problem is really the headphone input of my 2015 MacBookPro, which has a pop suppression, where I have not found how to turn it off, but I do not care now.

The solution is now the 3.5mm USB-C dongle from Apple which works great and is not expensive.

Now the experimenting can start :wink:
