Unusual fix for microphone noise issue

Post by Dubmaniac » Sat Nov 16, 2019 5:24 pm

I recently bought a pair of Sennheiser K3-U microphone bodies with a pair of M40 cardiod capsules. I started noticing that one of them was so noisy that it was unusable. I had seen something online about eliminating noise when using these without batteries (the batteries are no longer available, but they work with phantom power). The K3-U apparently needs some pressure in the battery compartment to work without the noise issue. Even a dead battery will do the trick. Today I cut a piece from a 5/8" wooden dowel to fill the battery compartment, and put it in there. It's tight, but it fits... and it works!

I wanted to share this to help anyone else who might have this issue. How about you? Got any creative fixes for problematic gear?

Very clever. Wood is smarter than an old battery that could eventually leak and severly screw things up inside the mic.

I recently used a piece of one of those rectangular pencil erasers to fix the Play button on a teacher friend's portable CD player (a classroom model with built in speaker). Sort of audio related, & I was right proud of myself for making it work.

My thoughts exactly. Now that I've got both these mics up and running, I am amazed at how good they sound for drum overheads. I could probably get away with only miking the kick drum and using these overhead to pick up the rest of the kit.

oh thats amazing! I'll have to get my K3U/MH40 out of storage today and check that out.
It used to be my favorite SDC for drums. But then one session it started sputtering and making noises. Changed cables, tried a different phantom power supply. Same noise. I never would have thought to try putting a dummy battery in there.
