I hit up Nelly Furtado's show at the MSG theater...I had a great time but I was noticing something going on with the right channel/right microphone...it kept swaying from loud to soft every so often. I wound up brickwalling the last hour of her show on the right channel but the left channel was just fine. When I taped the second opener, I noticed that the right channel dropped down on its own, so I cranked up the gain on the mma6000 (from 10 to 20).
The gain on the left channel stayed consistenly on 10 and didn't act up.
The gain on the right channel fluctuated on its own when Nelly came out after I dropped the gain on the right back to 10 before she came out, so I had to set it back to 20 hence the brickwalling which occured after the right channel got louder on its own. I know I can fix the right channel by copy n pasting the left channel over, but this is fucking bullshit. The microdots were in firmly, the interconnect was in firmly, the battery was basically new (one of those lithium 9V...I used it once for a megadeth show two weeks ago). The light on the mma6000 was blinking green....
I'm at a loss here....what the hell happened? I'll test the rig this weekend and see if I can duplicate the problem by recording by stero play some cds.

I've never had a problem with mine, except for user error (all loose connections). I'm pretty anal about checking every connection now, and have never had a problem.
I guess you just need to test it to see if it is still happening. Sorry, I don't have an answer, but hopefully I (and others) can learn from your misfortune.
+T for your troubles.

Check the battery voltage at the mic input with a volt meter. If it goes below 4.5 at the mic jack you will have issues. And what your describing is exactly what happens with a low voltage condition.

Hi Chris, thanks for the post. Could you recommend a volt meter to purchase from a website? I'll order one today.

Interestingly I had a similar problem last night with my rig (AT 853s>CA ST-9100>H120) only my problem was both channels. I noticed while trying to troubleshoot the problem that the light on the pre was not as bright as usual. Luckily I was at the Fox in Boulder where they allow re-entry and there's a store directly across the street. I quick grabed a new 9v poped it in the pre and voila. Now the really distributing thing is the battery I had in originally is a Powerex 9.6v which I got in exchange for another and which Thompsons assured me would do the job. This is a rechargeable and the charger said the bat was fully charged before I left for the show. I checked the Powerex this morning w/ a volt meter (from Rat Shack) and it only registered 3.2v. Guess I'll be speaking to Thompsons again this week.
