Squealing Neumann KM185

Recommended Posts

Hey friends. 

Sent my KM185 in for repair because it was squealing like this. See attached. 

 

They sent it it back saying they couldn’t replicate the problem.  

I was having no problem that day on set though!

 

Humidity or weird RF? This unit was supposedly manufactured after the latest revision but it’s the only things I can think that would be intermittent. 

 

Cheers

Adam

Could be the 48v power in what ever the mic is plugged into. The tone bursts are a bit surprising. If you can't recreate the problem then chalk it up to a one time thing.

Never had a problem with another mic. It’s  plugged in to a 633...

So weird!

I can‘t listen to this on my phone, but weird RF is always a possibility, especially with Neumann mics. 

I have great trouble with my KMR81i with the tx next to the mic on the boom. The mic has no rf protection and Neumann said they won’t do it, either. Maybe a similar issue with your mic?

Does not it scream when connected to another device?

Sennheiser returned it to me but I won’t have a chance to test again for a couple of weeks. 

Thanks everyone for the notes.
