I'm looking for a shotgun microfone for my dvc80 dv camera. I'm not sure what quality differences mono and stereo mics give??? I would need it for weddings as a secondary cam, and independent films.. I though of SGM-2X but can someone really tell me what is going on????

Stereo is a way to reproduce or simulate room. A shotgun mic is a way to eliminate room. A 'stereo shotgun' is worthless for both purposes. When you use a shotgun you want to capture the kind of audio that will go in the front middle of the mix, be it a stereo or 5.1 mix. So, in short: Get a mono shotgun. (But you may well record it in mono on both tracks - you could adjust one track up a bit to get a good signal and the other down to save the loudest parts from clipping.)

thanks for the post
