The DI boxes available to me when I first encountered the problem didn't have pads. I don't recall if I later tried with DI boxes that did have pads (this problem took place annually over the course of 10 years, and as I had a work-around, was low-priority)
The device that *really* fixed the problem is a ROLLS Promatch stereo level shifter.
I had ascribed this to an impedance mismatch, but now you've got me wondering. Since we started talking about this, I've been reading up on the lack of interest in impedance matching for normal audio connections, but am not so sure that that applies when dealing with a ~50 Ohm laptop headphone output.", "timestamp": "1521334802"}, {"author": "Danner", "source_link": "https://www.facebook.com/jefftk/posts/932279477332?comment_id=932314033082", "anchor": "fb-932314033082", "service": "fb", "text": "If you want something other than a Shure sm58 or sm57, you better specify it, or not care.", "timestamp": "1521242438"}]}
