Dear List,

I am currently working on a research project that involves capturing the HRTF of test subjects. Based on a review of the literature, I found that the Knowles FG-23329 microphone is commonly used for this purpose. However, I am having difficulty identifying compatible power supply options and suitable preamplifiers for this microphone.

I would greatly appreciate any recommendations or suggestions for compatible power supplies, preamplifiers, or alternative microphone solutions that could serve a similar purpose.

Thank you

Kind regards,
