If you are suggesting that
your follow-up connection is
mics to Presonus Preamp to Alesis Masterlink 3000 (to record a master), I guess I would need a little more detail... and you are on the hairy edge of my experience.
First, in my opinion, the mics are mono - you know that... which is why you have two. There are several Pre-amps available from Presonus - I am pretty sure they all provide phantom power (48v), so you should be good there, but some of there pre-amps are single channel in/out and many are multi-channel in/out. Just heads up, is all.
Personally, I would insert a mixer between the pre-amp and MasterLink. This will allow for more granular audio controls and provide insertion of various other audio controller/compressor gear. Mackie and Alesis have small mixers to do this. I realize the goal is to record the performance. Another option is to go the route of a Digidesign Protools set up and add a couple of additional condenser mics to pick up ambient audience audio. The ProTools set up will allow control of the various levels during mix-down. You essentially need a portable studio, so you need more components to what you are building.
At this point, you would have some choices. You can get a board feed off the mixer using a discrete aux sends (basically, you are taking a couple of "monitor" channels and using them to feed the camcorder - this is a "board feed" that I REALLY don't like doing) or you can take the output from the ProTools set up or you can take the output from the Masterlink. In each case, these would be XLR connections, so for the camcorder feed, you still need the XLR adapter.
When the mics to Presonus Preamp to Alesis Masterlink 3000 method is used, the camcorder XLR adapter's phantom power switch would be off. When the mics are connecting to the XLR adapter and then to the camcorder, the XLR adapter's phantom power would be on.
I dislike using a board mix - my suggestion is that the camcorder be used only for video. When the Masterlink is used, import that audio to the video editor when the video is imported, sync, and mute the audio that was captured by the camcorder.
Some lower-end XLR adapters do not have phantom power capabilities, so just pay attention. Both the juicedLink CX231 and BeachTek DXA-6 (and HD) can provide phantom power. But they are portable mixers designed for camcorders... not high-end audio capture/manipulation/recording devices like the other stuff you have listed. Just setting the expectation, is all...
If you are the performer, I would strongly suggest you find an audio engineer to help you with this. There are lots of things they know that only come with experience.
