I own an Audiobox Studio, I mainly record vocals on it. Yesterday I was recording some vocals and everything worked great, but today when I was going to add a couple more takes, when I turned the phantom power on (48V button) it started making all types of weird noises, kind of as if wind was "hitting" the mic. Note: NO there is no wind in my room to make such noise, I have NOT moved my setup at all since 6 months ago. Can anybody help me out with this? Thanks
 
Do you have another interface or mixer to test your mic and cable with?

Looking the other way, do you have an other cable or mic to test with your audio box?


I'd try to find a way of testing your mic elsewhere first, incase the audio box is faulty and potentially damages more than one mic.
 
No :/ I don't, but I have another computer I can install it to which I am bout to try,, first time I move this mic in 6 months
 
Worth a try I guess.
What kind of environment do you have? Humid?

I've heard of mics acting out and needing to be dried out, carefully.
 
Its mainly a dry environment, Especially now that winter has started to hit
 
Swapping mics/cables/interfaces is really the only (simple) way to prove what's happening.

Does engaging phantom power cause noises with no mic plugged in?
 
I would start by cleaning the XLR connections on the cable, audiobox and mic, any bad connection will cause the phantom to be intermittent. The next thing I would do is check the cable, how good is the cable? Some cheap cables do not work well with phantom. And third as suggested put the mic in a dry warm place for a while.

Cheers

In the absence of substitute equipment, you could use a meter to test for 48v dc at pins 2+3 with reference to 1.
You could also test your xlr cable for continuity across and between all three conductors.

If you don't have a meter or aren't comfortable doing that, don't worry about it. :)

Either way, do what Alan said too.
 
Sorry; Sopranos gag.
Brogan Adjustment is banging the crap out of it with a shoe. :p

I know you said it's dry, but this is usually the outcome in these threads.

Might be worth putting the mic in an airtight box with silica packets, or storing it a warm dry part of the house over night. An airing cupboard maybe?
The guy in that link placed his under a bulb for a while. Not too close though!
 
Wow THANKS for that link, I am thinking, the mic came with a storing bag that I've never really used,, If I put the mic in the bag and lets say leave it in the kitchen/restroom over night were its nice and cool (unlike my room) that might "fix" it IF I have the same problem as the user from your link
 
Cool.
It'd do no harm, and at very least you'll rule something out.

I think unnatural heat would do more good than cold though, so if you have a room with your hot water tank in it or something, or even a little shelf above a radiator, I'd go there.
Use your own discretion; You obviously don't wanna get the mic so it's hot.

If you don't have any silica, I guess putting some dry rice in the bag would be sensible.
I've never heard of doing that before though, so it's your call. ;)
 
Ha, I got some laying around in boxes,,, quick question since Ive never really used it before,, Do I like Open the silica bags into the Mic Bag??

This is how I fix mobile phones that have been in the water/rain, take the battery out, take the back off it, place in dry rice in the sun for 5 or 6 hours, put battery back in phone works.

You leave the silica in the bag, just place the silica bag in the mic bag.

No,no. The little bags on their own do the job.
They have a limit though. If yours have been lying in open air for months, they're probably saturated.
You can dry them out on a radiator or in a oven to be sure they're good to go.



Let us know how you get on, yeah?
