So here is my setup
480s/ck62->m148->sd722
I've always been kind of skeptical about the omnis as one is always hotter than the other. When I use them i usually just adjust the levels accordingly.
A few times (this weekend included) the level on one side seems to gradually drop after running for a while. It wasn't until about 6 minutes into the second set where it started to drop.
Normally, this would seem like maybe a problem with the preamp. It still had plenty of power at the end of the show so i'm not sure that is it. Also does anyone know if power is separate to the 2 channels on the 148 or is it a pool of power used for both channels. (i'm sure i'm using the wrong terminology there).
The reason I'm thinking it might be something with the omnis is that i've only ever seen it happen with the omnis. Ran the cards and hypers without issue more times than i can count.
I was going to set things up this week to run some controled tests but curious if anyone has any thoughts or similar experiences

If it is only with the omni's and everything else is always the same, it is the omni's. I kind of think it would not be the diaphragm failing so it would then be the electronics in the mic. I think you are already suspecting the mic and I think you are right. Try switching the capsules and see what happens. If nothing changes that would indicate it is the electronics.
Sorry. But is it all fixable.

Gray, When this happened Sat, was it the left or right channel? Also, do you use those long cables with your other caps and not have issues? When you test them, try all your cables, and do both the 148, and direct into the 722 and this should indicate if the mics are the problem, or the Oade preamp. Great seeing you guys, by the way......

it was the left (the side over by us).
i will test everything. i'm 99% sure it happened with a different set of cables last time but not willing to rule it out yet.

You know, I wonder if it could be that we were just getting more loud and rowdy over on the right side as the second set went along, and it just made your right levels look louder compared to the left? >:D
JK.......hope you get to the bottom of it. I have never heard of a capsule doing that before..........good luck!

I've had a weird thing happen once or twice with my 482's that kind of sound like this, except it happened right at the outset. I turned on phantom, and one mic was producing a way low signal. I turned off phantom, unplugged the mic, unscrewed the cap, and then put it all back together again and it's been fine ever since. It was so weird I almost thought I must have hallucinated what happened. I think it may have had a weird charge on it or something, or it wasn't seated correctly? Not sure if that is even possible. But I'd just run some tests and see if you can reproduce the behavior.
