Thank you very much Hall for the response. I will order the latest version of the audiomoth and I will test with my microphones (EM172). I think it's worth it. My olympus LS11 and my sony PCM M10 give excellent results with the EM172. My idea is to be able to connect my parabolic dish to the Audiomoth to carry out night migration monitoring. Thomas

Hello, I would like to know if tests have been carried out with primo EM272 capsules (new version of EM172)? The note "Using AudioMoth with External Electret Condenser Microphones ", only mentions the EM258 capsules. The latter displays an operating voltage of 3V against 5V for the EM272. Could an EM272 capsule still work? Thank you very much, Thomas Zgirski
