any gefell mv692/m70/m94 users here? (soundfiles)

hey,

i got some mv692's and quite a lot of capsules. they all sound quite different, but i have two m70's and m94's which sound quite similar. i just don't know if they should sound the way they do. the m70's sound a bit trashy and vintage-like when used as drum-overhead, the m94's sound very harsh and can't be used as matched stereo pair.

could anyone have a short listen if these soundclips sound like gefell's should do? i want to buy a um70 or m71 too, but i'm not very satisfied with the small diaphragm capsules yet.

cheers,
flo

The UM70 is a nice capsule. Very classic sounding. There are a few fakes and retreads around so be careful when buying. thumbsup

there is quite a lot of gefell stuff around here in austria/germany, but you need to be lucky though to get good stuff, that's right.

UM70 and M70 are two completely different animals. UM70 is a large diaphragm PVC capsule like in the old U47 tube mics, while the M70 is a small diaphragm nickel capsule. I believe the poster is talking about the later, since the M94 is a similar type to the M70 but is made for a more distant pickup and has a slight bump in the high frequencies if memory serves me correctly. I have both and they sound extremely smooth and detailed, not harsh or trashy. Maybe yours need some TLC or your mic amplifiers have some problems.

If you are thinkinh about buying some UM70 capsules for your MV692 bodies, try to avoid ebay since you never know what you are getting, and besides, a new UM70 capsule is still available from Gefell for about $550 US. The used ones usually fetch about $350-$450 so why gamble on an abused capsule when you can get a brand spanking new one for not much more. A reskin of an old capsule will cost about $300 -$400 anyway. Play it safe and buy new.

Colin, just to be clear, I was answering his question as to whether a UM70 would be a nice addition to his capsule collection...

he he, thanks guys...

i already bought an um70 for about 240$ - if it's not working properly i'll send it to gefell. i already made the experience with mbho (haun) SDC's - sent them to the HQ and they sounded 200% better.

what does mr. drefahl do? service for gefell mics? is he a worker at microtech gefell?

i still don't know if my SDC capsules sound like they should... anyone had a listen to the soundfiles?

cheers,
flo

Peter owns an audio shop in Konstanz Germany called Drefahl Audio. He sells new and vintage gear and is a very good mic tech. I have bought many refurbished Gefell mics from him and he is an expert in Gefell and other German mic repair. He can reskin UM70 capsules with PVC or mylar, but I would go straight to Gefell for that. If the diaphragm is ok, and the problem in your UM70 is an electrical or mechanical one, he can service it and he can clean and check out your sdc capsules as well.
He gets really nice vintage mics that are usually in pristine condition for sale as well. He is a really good guy.

Is the M94 also a Nickel capsuel or Mylar ? ie the equivilent of a Microtech Gefell 295 mic.

M94 is equivalent to M294
M70 is equivalent to M295
both are nickel. I had a few of them and the differences in sensitivity and sound were too big for me.

i know it's an old thread but probably someone will have a look at it.

all my m70 and m94 were serviced by mr. thiersch in schleiz/germany and the soundfiles linked here do represent defective capsules. some of them had holes in the membrane, some were tensioned too tightly and some had to be cleaned.

best,
flo

Ah, good information! Thanks for the update -- late though it might seem. heh

Also, just to modify something said above, it's the M94 has the upper range boost, the M70 is flatter -- which is not to say uninteresting. It's got a great vibe -- the M70 692 combo is one of my favorite mics.


Cheers.

Years later....

The mics need service if they doesnΒ΄t sound good.

The amplifiers unfortunately fall short of the high quality of the capsules in their original state.
To fix this problem, microphone engineer Andreas Grosser offers a complete rebuild of the impedance converter, replacing everything except the output transformer and the 60V generator. The old field-effect transistor (FET) is replaced by a circuit with two modern FETs to achieve a smooth characteristic.

The replacement noise level is significantly reduced and more than twice the sound levels can be transmitted without distortion. The sonic characteristics are now similar to those of the M582 tube amplifier.

A good amp & m94 should sound like that:
