Studio project B1 issue

    Greetings,

    I have a SP B1 mic which has been causing me a lot of issues. It seems like it get hot/cold while I'm recording. My levels change constantly. Any ideas? I have tried using Phantom power from both my mixer and a preamp and they have the same problem.

    thanks.

    I have a B3 that seems to have low levels (and sometimes rumbling noise) until it warms up. Seems like it needs 10-15 minutes to get sounding "right". Not sure why this is - it has no transformer.

    Mic's and preamps and other electronics do sound better or at least more consistent when warmed up. It takes a C414 sometimes five minutes to completely stabilize for instance. My guess however is that them B1 has gotten wet from breath humidity (or actual humidity if you're in a very humid state) and the capsule is fading in and out. This is not uncommon at all on condensers and is one reason to use a screen type pop filter. If this is indeed the case, let the mic dry out and store it in a bag/box with a dessiccant package. Get a decent screen pop filter or two. Metal is better than pantyhose.

    The only other thing that comes to mind is a cold solder spot on the phantom circuit inside the B1 itself.

    Thanks

    I appreciate the feed back. Yesterday I changed chords and even switched to a different recording device and still the same problem. Today I fired up everything and it seemed to have stabilized.

    Thanks.

    Today you fired up from scratch with a dry mic. I'm guessing it is a breathe humidity issue. Do yourself a big favor. Get a little notepad to keep with your gear. When you have issues write a journal entry describing the problem, how you troubleshot it, how you fixed it if your did. That way you can keep track of trends like what mic/what cable/what pre/what was the weather/etc.

    It's kind of like teaching. Whenever I began teaching a new class I made lesson plans for myself. After a couple of years I didn't use plans for that class but if I was handed a new class even on a related subject I began by making lesson plans for that as well. Well, what you are doing is teaching yourself so the journal becomes your lesson plans and text book. In today's world I am a location recordist and still document as much as I can, it's just usually with pictures etc on my DroidX or written into the session files of the DAW or both.

    I want to thank everybody for the great advice. :) You are absolutely correct about the taking notes, keeping history I don't know how many times I've forgotten how to reconnect my monitors. So I guess it must have been humidity or some external source causing my microphone problems because I recorded without issues for 5 hours yesterday. BTW I really like the SP B1 microphone I use it for just about everything but then again I just started recording seriously.
