Audio, hi-fi and car audio - recording a 3 way conversation in a room

"p s" wrote in message

i am recording on location a conversation in a meeting room whilst it
is being videoed (recording straight to audio track of the video).
this video will then be played back in a large hall on a big screen,
at a loud volume. i am toying with the idea of using a PZM mic
mounted on the table in the middle of the three people, out of camera
shot, to record the audio track - straight into the cameras XLR
input. my other choice would be to use an omni-directional mic on a
boom stand of some sort but i have left it a little late to sort this
out. does anybody know if the PZM will be a good choice? i will be
doing some post production on the audio track (noise gate,
compression etc.)... if not then can someone recommend a better
solution.

Good question for alt.audio.pro.love-sound and/or rec.audio.pro.
