Suitable adapter cables - DIN (Tuchel or Binder) to XLR are available.
This morning I received a 15ft cannon-ended length of what I think is the old Belden cable. (Gray rigid, corkscrew shielding coming through jacket, with a neat old smell I haven't smelled in years.) Anyway, I hooked it up to the output of a 251 clone power supply and did several A/Bs with two different mic pres, comparing it to Mogami and Canare cable. You could certainly hear a difference. More definition in the lows and smoother highs. Level seemed the same. This was a vocal test of the same repeated musical phrase and counting down from 10. Next I will try acoustic. Quite impressed.
You said you hooked it up to the “output” of your 251 clone power supply ?I think Klaus was speaking of connecting the Belden cable from the microphone to the “input” stage of the power supply ?
So, a question-- using a mic preamp with a transformer-coupled input, is it better to aim for matched impedance with the microphone, rather than bridged impedance?
Klause, tx for a very interesting thread and for all the work that went into it. I have two 67's. One ancient, the other the earlier reissue, in the 90's I think. The FR looks identical but I always find myself preferring the older one. Capsule tension? Can the newer cap be detensioned?
