Question about Neumann U87 Professional Microphone

1 Answer

Neumann U87 no signal

I have an older U87 and I haven't used it in a while(maybe 18 months) I tried to get it up and running the other day and couldn't get any signal out of it. It wasn't anything else in my signal path as I checked it all with another mic and ti was fine.

    I also have an older Neumann U87 with the same problem. When I bought it off eBay from a pawn shop in New York, it worked fine....then it started cutting in and out. Doesn't act like a short at all. When it allows sound to be heard, it actually fades out. Thought it may be the phantom supply, so tried others and the same problem happens. This mic was serviced before I bought it, so I don't have a clue what it could be.

Who serviced the mic? Send the mic to Tracy Korby or Klaus Heyne.

The capsule can get dirty and then behave in the way that you describe. It is possible that a simple cleaning by a professional will bring the mic up to spec.

My u87 cuts out when you get to close but comes back on in 2 secs seems to be wind pressure from singing. many thanks Graham


problem is a dirty capsule caused when fogged with humidity from breath it shorts out temporarily. it maybe possible to have it professionally cleaned but may need to be replaced. DO NOT USE FOAM POP FILTERS. Spend the money on a metal one. back off if you wanna save some loot.

My U87 microphone won't power up...no signal. does anyone know why this may be happening?


Was it working fine before it stopped powering up? The U87 is a condenser microphone so maybe the reason it is not powering up is because the phantom power on your interface was not turned on. Plug the U87 into your preamp and then switch on the phantom power (48V) to get it powered up. If that doesn't help, there must be an internal fault within the microphone or in your preamp.

Usually the distortion is from over gain on the preamp or the spl of the actual voice on the diaphragm have him step back a few steps and try again.

NEUMANN U89 SOUNDS VERY FAINT


Your mixing board may not be supplying 48 volt phantom power, which is required by the U89. Check with a voltmeter from pin 2 of the XLR to pin 1, see that it's 48 +/- 4 volts.

Neumann U87 is distorting and cutting out


As condenser microphones 'mature' they may accumulate contaminants on their diaphragms, which in turn provide a relatively low impedance bypass for the bias voltage. To check if your microphone may suffer from this effect, hold it close to your mouth and breathe (heavily) a few times on the head. The moisture from your breath will condense , and if there the capsule is compromised by contaminants, or if it has developed other flaws, you will hear an increase in frying sound and/or complete loss of output.
Sometimes the capsule can be cleaned, thus extending its useful lifespan. At the risk of causing irreparable harm to the heart and soul of the microphone, this procedure should not be attempted by an inexperienced specialist! If in doubt, sens the microphone to the Neumann Service Department in Old Lyme, CT or another qualified specialist.
