Title: MG m300's got wet in the rain
Post by: mgtaper on July 27, 2010, 11:27:35 AM
I was recording this past weekend @ the Grassroots festival in Trumansburg, NY and the MG m300's got wet in the rain on Saturday.

After the rain stopped, the right channel was behaving strangely so I shut down and broke the rig down.

I dried the mics off put them in their Pelican case and when I got home, I put them in their wooden box with a desicant pack.

I have not powered them up until I feel they are completely dry.

I was told by another taper with m300's to NEVER let them get wet.

Just wondering what else I should do besides pray?

Thanks in advance for any help.

I dropped my mk-4 caps in a toilet once while rigging up for stealth.
I let them dry out on a countertop for 4 days, then used them for a gig with no problems.

Hopefully yours will work fine after drying out too.

I've heard rumors that Schoeps are "water proof".....  or at least resistant to the rain.  Anyone know if that is actually true?
That's literally flushin money down the toilet.....  eh Ed.   ;)

My only guess is to let the 300's air out for a while........  maybe even take em out of the wooden box.  Might not hurt to "open" up the mics too if possible.

This gives new meaning to MG users description of the Schoeps sound as "muddy" in the low end.  :P

That is a 'gearing up' horror story.   That's a good reason to always take a seat.
Note to self... do not buy any mk4's from Ed.... :P
You're just lucky the water wasn't blue or green from one of those cake bowl cleaning things.

Regarding the desiccant, I question how effective it is if it isn't fresh/new, and out of a sealed container.

Schoeps rain resistant?  No way.

About 2 years ago I had a pair of Gefell m200's that got soaked in the rain, after the power was removed from the mics.  I could not fight through the crowd to take the mics down from where they were clamped to the sbd scaffolding and they got drenched. 

As I said, the mics were NOT powered up duiring the drenching.  I let the caps and mic bodies air out, in the open air for 3-4 days and there were no ill effects afterward.  I'd get the mics out of that box and let them air out openly.   Good luck!!

Yes, get them out of the box and let them dry for a few days.  Maybe put them up in the sun next to a window inside the house.

The sound guy at one festival (Hillside, Guelph, Canada) left a pair of NT2000 out and it started to rain.  I asked if he wanted to take the mics down, and he said, no, those were just his beater mics.  He saves the Neumann's for the times it doesn't rain.  It just hurt to see someone intentionally leave their mics out!  If you've access just put a small umbrella over them...

God dam that is a shame...I would never let my NT2000's out in the rain.......And they do compare nicely to the U89's but to consider them beaters is just ridiculous...... It just goes to show one mans trash is another mans treasure....I love my rodes....

I powered them up last night and tested them out. Both mics are working! ;D

I ran them for a couple of hours and they seem to be working perfectly.

Thanks for the the tips and horror stories.

I actually was using an umbrella, but I was too close to another taper's umbrella.

I'd not advise submerging them while under load as others have implied, but should they get wet there's really nothing there that would absorb water to where it wouldn't dry out.  I'm prolly all wet on this but that's how I view the casual rain incident.

It can take a long time for corrosion to develop.. and there is always the threat of the dreaded whiskers.

The most importaint thing to remember with mics is this.

1- Unscrew the capsule from the body if possible.
2- If the mics are omni capsules put them on a few layers of paper towel face down meaning the front of the capsule towards the paper towel.

3- For mics like DPA or my mics * omni * place them so that they hang from the cable and the front of the mic is pointing towards the ground. And let air dry.

4- For Cardioid mics we need to see if water has got behind the capsule near the contact pin. If it has you must put them on paper towel with the threads of the capsule facing towards the paper towel and leave it for a few hours then flip the capsule so that the face is facing down towards the paper towel. Flipping them every few hours.

Direct sun exposure is not recommended and the capsule should not get hotter than 100 degrees F..

5- For the preamp its best to drain the water  out by placing them in a mic stand and having the XLR facing towards the ground. You do not want to drain it towards the Center pin of the mic body.

6- For large diaphragm condenser mics.. Air dry only by placing the mic upside down with the capsule facing towards the floor in a stand. If however the body is full of water you want to get that out first by placing them XLR down first.

I would let all mics dry out for no less then 4 days.

i had chris's ca-14 omni's get drenched, I followed his instructions for drying and had no residual issues. I also noticed during the rain that despite getting hit fairly hard it was almost impossible to notice the effect of the rain sonically on the recording.

Really? I would think most any mic flying at a festival in the summer sun is likely to see temps of more than 100 degrees, especially when colored black.  ???

From the Microtech Gefell site:

"The mic’s capsule, designated “M3,” employs a 16mm Mylar diaphragm, coated with gold. The housing is ceramic rather than the more-typical metal; the advantage, derived from the company’s work on test and measurement mics, is that ceramics have less susceptibility to change due to temperature."

This was one of the reasons why I chose m300's.

100F is just a suggestion.. You can run mics hotter than that but you have to be careful because condenser mics can be damaged by direct sunlight and high temps. Windscreens do help with this issue.

That's a good reason to opt for silver mics, when there is a choice... Or to wrap your mics in aluminized mylar and then cover them with heat shrink, or umbrella..  At least for the festival tapers.

I'm sure some of those sun baked mics get reaallyyy hot... I wonder what impact that has on sound quality at the time the recording is made?
