Did I kill one of my mics? (Beyer CK930)
« on: October 31, 2019, 12:11:57 PM »
Set up for Ween last night and noticed one cap was getting levels WAY lower than the other. Did some troubleshooting. Swapped cap from one cable to the other. Changed batteries in everything. One cap was the issue.

I'm running the CK930's > Naiant IPA so there is no off switch to turn of the phantom. I'm thinking that may have killed it since you can't switch off the phantom before disconnecting the mic.

Anything else I can do besides send it back for repair...and if so any idea what kind of $$ I'm looking at to get it repaired?

I'll post a sample in a bit. I ended up pasting the good channel over the bad one and salvaged the night, but definitely sucks on the first night of a 3 night run. Going to run my DPA4080's instead tonight.

But you were already having the problem before you swapped the caps right?

Problem appeared when I hooked everything up. Swapping the caps (Left and right) was to figure out if it was the cap, cable, IPA or input on the recorder (even swapped everything from CH1/2 to 3/4 on the Mixpre-6).

You can't have damaged the capsule that way. A capsule is just an air capacitor set in a specialized, acoustic "mini-environment".

Powering down before you disconnect a mike isn't to protect the mike; it's to protect all the other equipment from the spikes and thumps that can be generated--especially the power amps and loudspeakers in a P.A. system. If you have headphones on, it will help protect your ears as well.

So stop blaming yourself, OK?

--best regards

P.S.: BeyerDynamic US service was first-rate the last time I had any dealings with them, but it's been a decade or more. Please let us know how things go from here on.
