I put it quite high, it records every whisper from the groom but I rather have it that way, the audio levels from the groom are always as they should be, only the bride needs quite some adjusting, that's because when she turns her head each time away from the groom to read from a page during the vows. I can hear some more noise from the adjusted audio from the bride in my headset but that one is much more sensitive then the speaker from a tv. On a loudspeakerset of a tv I hardly hear the difference.

Roger: I use a T20MX

I agree with Scott. Don't be cheap with your audio.
You are taking a lot of steps to ensure that you are getting good video. So don't neglect your audio. the iRivers will burn you. And also they are hard to come by as they haven't been manufactured in 4 years. Only refurbished or used units can be had, and might or might not be reliable.

If you really want non-wireless recording, then look into the Zoom H2 (which is the cheapest of these), Marantz PMD620, Edirol R09HR etc. All of these units will enable you to use lav mic input if needed, line input, as well as built in mics for live recording. And best of all you can record in WAV audio format. MP3 sucks for audio capture. For ipod, great, but not live critical audio.

Now if you go wireless go with a Sennhesier G2 or Sony UWP-V6 wireless systems. Make sure that you DON'T purchase a 700mhz or higher system though. As these signal will be going away after FEB 2009.

crap man, my G2 is 700Mhz series. i will still be able to use it, right?

Don't know. It should work, but can't say about reliability.
Sennhesier has pulled their 700 mhz series units. So this should tell you something.
I would contact Sennheiser and see if they are dong anything for their customers.

I think that I read that they might be some sort of mods or exchanges.

i will contact them this week and find out. I think for using it during weddings, it
probably would be ok, but know knows.

I'm not worried and I've got a 700mhz unit. On the bright side... you won't have to worry about colliding frequencies with the church system because they'll revamp theirs first. :)

I have a Zoom H2, 2 AT Pro-88W's, and a Sony Bluetooth mic for my Sony HC3. The Sony bluetooth is surprisingly good and very simple to use. For quick stuff I often reach for it instead of having to wire up the XH-A1. If it's a stable environment I will use wired AT25 lavaliers (built in 20' cord). The Pro-88's are a little finicky for interference, like if you get too close to a fluorescent ballast or if the subject gets more than 25' away.

I'd like to find a Sony bluetooth with a mic jack that will work with non-Sony cameras. The model I have has a built in mic and requires the proprietary Sony hotshoe. Very convenient and great range.

The H2 has great sound quality but the files get quite large in a hurry. I don't see any low bit-rate settings. It seems to be all or nothing and the GB's start racking up pretty quickly.
