Hi all
I am just wondering if anybody can fill me in on the difference between these two mics. I have just bought an UM92s after beeing very happy with the UM92.1s I have been allowed to use for a while. The mic will be in my hands in a few weeks, and I hope to get the chance to A/B test (or actually A/B/C test...) the UM92s, an older UM92.1s (ca 1995) and a newer UM92.1s. But I am also interested in knowing the technical differences between the two mics, and really, all the info I can get....
Here is what I have found (thanx to the seller of the 92s)
"The difference between the Gefell 92S and the 92.1S is.... the 92S had a heater voltage adjustment inside the microphone. It was made for running cable lengths of longer than 50 meters. Gefell wound up not being satisfied with having it in the body of the mic. With the 92.1S the heater voltage adjustment was moved and is housed in the power supply. That's the only difference between the two models."
and
"In addition to the heater voltage adjustment location change, they also changed from an EC92 triode tube to an EF86 pentode tube. There was some additional RF noise rejection circuitry added (a bad idea which most people who use them to record have removed). According to Oliver Archut at TAB Funkenwerks, the output transformers on the newer versions were also improved.
I personally own an M92S and a UM92S (the multipattern version) and have found them to be excellent mics. I highly recommend that you replace the original East German tube with a Telefunken tube. You will notice an immediate improvement in the sound quality. As far as I can tell, the mic was built according to the same schemeatic as a Gefell UM57 but with improved components."
Big thanx in advance to anyone who has any input on this subject:o)
Best regards,
