    Out of the blue one of my 414`s has lost its recording level. I'm using a pair for drum OH`s I checked the pads, phantom power and everything seems to be adjusted as it should be. I even changed cables and tried different channels but, no difference. so i'm pretty sure it`s the mic. because I have to crank up the pre amp gain much higher on the problem mic to get the same recording level as the other. this has never happened before! did I blow the capsule?......anybody have any comments?

    Most likely a cold solder point.
    I've had to re-touch a few of them on the capacitors on the pc board.
    No big deal, open it up and use a magnifying glass to scope it out.

    Just be careful about holding the iron on the solder point too long.

    I had a similar problem with an AT 4047. The level dropped way down, but I also had rustling noises underneath, and strange oscillations. The biggest problem was the drop in level.

    It turned out that the problem was condensation. I had used it on a close-up vocal session and then put it in a plastic bag without a dessicant. I know it's a long shot in your case, but you might like to try putting it somewhere dry and warm for a short while. I put mine a few feet above a radiator, but it's' important to make sure the rising air isn't significantly above about 30C. You don't want your diaphragms to sag!
