Hello again,
Transformer mics: you might also mention KMR81 & 82, shotguns.
Exotic upper class: ever tried KU100 dummy head, or M150Tube and TLM50 omnidirectional, KM120 single-diaphragm figure-8, KM131 flat omni, KM143 subcardioid, GFM132 boundary layer, RSM191 stereo shotgun? If we only did mics like those, we'd never survive. But we do keep making them, for some specialists amongst the sound engineers.
TLM49 as "vocal mic": we do know that this mic has more applications than just vocal. Basically, you can use most of our mics for everything, you just gotta put them in the right place. My prefered question is: "what's your BEST grand piano microphone"? Gimme 10 hours, and I'll go into the details of our 25 mics for that application...
On the other hand, you got to give a name to the baby. And the main intended application WAS vocals. BTW, the U47fet was never designed as a kick drum or double bass mic, it was the sound engineers who found out that it's a fine mic for that application. When people will tell us that the TLM49 excels as a dobro mic we might even put that in the documentation.
Freq.Response: (see the attached file, showing some responses, at 1m distance from a coaxial speaker system, in OUR measurement chamber, etc etc etc) I double checked (yes, I did!), comparing the last 10 U47fet we had in service with the curves of the first batch of TLM49, and.... U47fet response was 0...1 dB lower, from 100Hz on down. What does that tell us?
A. Your specific U47fet(s) might be bass-heavy.
B. Kick drum, in your specific positioning, might saturate the U47fet electronics/transformer (depends also on the setting of attenuation switches, pre-amp load, 50ohm or 200 ohm output setting etc. etc.) Have an oscilloscope, an analyzer and the exact levels while you're recording, and one can tell on which part of the amplifier's curve you're working.
The old manuals of U47fet (all available on our website...) show the gradual roll-off. But do keep in mind that the shown curve was the "intended median curve" at the time of printing. What was shown in the 70s as a small step in the mid lows is now more correctly shown as a gradual slope. BTW, to my knowledge the U47fet wasn't very popular at the time it was manufactured....
Evaluation: Yes, we even test digital electronics in U47 housings, and compare that to old U47s, and old U47s in modern housings, and so on. So the engineer and artist do NOT know what they're working with. BTW, the old U47 does not always fare best.
Self-testing: Actually, I do like the sound of TLM49. I also do have a U47fet at home.
TLM193 and sound preferences: there are actually people who like that microphone, believe it or not. They might be working in voice over studios, or use it for strings, or high pitched female voices, or brass. It might not be your prefered mic. But that's why we do make quite a lot of different (!) microphones, and not just one model. And every once in a while you might find one of the new ones to your liking. Perhaps even one of the "cheap" ones. Shall we leave it at that?
I'm off for 3 weeks now, in a no-mail & no-microphone area (!), so I won't be able to answer further questions during that time.
Best regards,
Martin Schneider / Neumann Mic. Development
