Default Avantone CK-1 Problem

I have an Avantone CK-1 that I use mainly as a drum overhead. I have had it for about 5 years, but I haven't used it much. The last couple of times I have had it out, I had an occasional low level scratchy distortion, a hiss that sounds a bit like a worn out vinyl record. This continues even with no audio signal. It goes away if I unplug the mic from the interface and plug it back in, or if I turn phantom power off and then on again. But then it comes back again somewhat randomly. It has ruined some tracks. This has happened with different equipment and different cables, so I am pretty sure it is the mic.

Here is a link to a very short clip of the distortion:

Does anyone know what is causing this or what I might do to fix it?

That sounds like normal hiss, not distortion. Did you change your signal path recently? Cables, preamps, compressors, eqs, and even power supplies can add low-level hiss.

If you record hot enough, you negate the noise floor. This is very easily dealt with in 24bit.

Finally, a bit of hiss can be a good thing. I have a theory that digital is so clean it creeps listeners out. Humans don't function well in complete silence. We like a bit of white noise so we know we're not alone. So allowing a bit of noise in our music recordings let us know they were recorded in a real space somewhere. Complete silence is akin to the uncanny valley.

Yeah, it's hiss, but it rises and falls, and sometimes crackles. I just grabbed a short section from the very beginning of the track, so you can't hear that variation. And it goes away for a while if I turn phantom power off and on again. It's audible in the track. It doesn't happen with other mics. It's not normal.

Default Another clip

Here is a clip from the end of the track that shows the hiss more prominently:

I don't know if this will be helpful, but Avantone CK-1's are, in my limited experience, just very noisy mics.

I bought a couple of them since they were so inexpensive and because my Avantone CK-40 (large diaphragm stereo mic) is so astonishingly good.

Both of them had a lot of hiss and one had a hum. Avantone US let me send them in and "repaired" them for no charge, even though they were used. For both of them, I got a technician's report that explained what was done.

They were both exactly as noisy as before. And it's not my signal path, I have a lot of SDCs (Shure SM81s, Mojave Audio 101fets, Octavas, AKGs) and they are all very quiet.

So I have to assume that with the CK-1's that's just what you get. Pity.

Ah, that is good to know. It sounds good when it is working properly, but perhaps it is not worth bothering with.

Thanks.

Okay, I hear it now.

That sounds more like a short, like something's connecting and disconnecting intermittently.

Have you tried another cable?

If Avantone's willing to repair out-of-warranty mics, then I'd send it along to them.
