From the frequency response graph provided at the Neumann page, U87ai has a -3dB/octave HPF, which sets in as high as almost 1k. I normally don't find it very practical to use, and tend to prefer the HPFs at my preamps, if any.
@@curtisjudd Welcome - this U87 HPF must be meant to fully compensate for the proximity effect when the U87 is used close up. Now, with the old U87 version, this made more sense than with the U87Ai one, which is 6dB hotter, but without increased headroom, and therefore tends to distort much earlier when used in very close proximity... This is why I do not find much use for this HPF: it's too strong on the U87ai when it's used with a reasonable distances from a gain perspective.
Thanks for the info and demo about high pass filters, Curtis. It was certainly helpful and interesting.
Thanks for the question. 👍

Thanks Tom, good to know. Odd that they don't just list the HP specs. 🙏

no beyerdynamic ?
Not that they're bad microphones, I just don't have any in my collection.
