Hi, and thanks for the great open design! I just put together my first ThatMicPre. However, the output is low and distorted even at the max gain. I've included some pics! Would appreciate it if anyone notices anything obviously out of place or can suggest troubleshooting advise! I'm running it into a Scarlett interface on using the line in port on the back, and powering off a bench top power supply.

Hello guys,
thank you for this great project.
Please, I have a problem with the Matlab file.
I'm trying to use it but it gives me error.
Please could you inform me how to use it? What values and where I must put to give me results?
The version of Matlab that I'm using is R2023a
Thank you in advance.

Hi zraxix,
My first question is, what DC voltage are you suing ac power supply? 48V or at least 24V, I hope?
If that is correct then I would take out a multi-meter and measure the DC voltages at the V48P, V35P and V18P nodes.

Hi georgenikolaou
Hard to help you without any more info. What is the exact error that you are getting?
How much prior experience do you have with Matlab or Octave? The file is a normal matlab function, the help text for the parameters show if you type "help micpre_gain2res"
Hello ojg,
Thank you for your reply.
Please attached you will find the error that it shows to me.
To be honest, I don't have an experience with Matlab.
Can you imagine which is the problem and what to change to have the results?
Thank you very much in advance.
