Re: wedding audio

You should definitely put a wirelss on the groom, you can hide the lav in his boutenirre and you'll get the vows very well, even the officiant when he's within arm's length. Mix that with ambience from the shotgun and you have a bare-bones coverage that can work. That's what I always used to do.

The next step up would be to get a small portable mixer like the Beachtek, so you could add the PA system into a mix while shooting. Many churches and temples have wirelss hearing aid/amplification systems for deaf members to borrow: I have had great luck tapping into the church PA thru the reciever for one of these. It let me get a free wireless feed of every mic'ed area of the church, already mixed, awesome coverage. Scout it out at the practice sessions before the real ceremony. Bring fresh bateries for it and the apropriate adapte cord, usually a stero or mono miniplug for a headphone, matched to whatever your audio input takes. Adjust impedance with the receiver's volume control.
