Microphone output impedance

Jules Ryckebusch All Messages By This Member #37128 Question for the group on this. What is the?correct frequency to measure the output impedance? I am assuming referenced to 1Khz. Or should?it be 20hz to 20Khz? What do manufacturers spec? I checked DPA's site and they just list a value. -- Best Regards, Jules Ryckebusch 214 399 0931

What is the?correct frequency to measure the output impedance? I am assuming referenced to 1Khz. In the absence of a comment saying different, impedances are measured at 1kHz. Or should?it be 20hz to 20Khz? Some manufacturers indicate that impedance may vary over the audio range. What do manufacturers spec? Anything the mktg dept deems valuable. Seriously, some manufacturers specs are laughable. I checked DPA's site and they just list a value. I've found that, although their designers are excellent, their technical communication is far from being as good. -- Best Regards, Jules Ryckebusch 214 399 0931

And there was the FDA... ;-) Jules toggle quoted message Show quoted text On Sun, Feb 2, 2025 at 10:07?AM Jerry Lee Marcel via <jerryleemarcel=[email protected]> wrote: Le 02/02/2025 à 19:54, Jules Ryckebusch via a écrit?: Question for the group on this.
