Doing a webcast need audio help

Hey guys. I am getting into doing a webcast for a church event. Need some help with audio. What I would like to know is your opinions on set up and what mics to use. I would perfer it to be wireless. And as portable as possible. I think I will have to come up with two options. One if the church has sound system already install. If so how would or should I tie into it? Should I just mic a speaker? Etc.?? And two what if the church has no sound system. Would I need to get a board? I would like to get 2-4 mics and place them around the room in this situation but what kind of mics should I get? What options are out there. Any help, advice, opinions is greatly appreciated.

You need to say what type of event, what type of church, what sort of acoustics and so on. In the absence of this info, I'll make a few general observations.

1. With any event, planning with the contributors is critical. Talk to the priest, vicar, choirmaster, band leader and anyone else, but do it without annoying them.

2. Bear in mind that success with radio mics, much more than with cabled mics, depends on the sense and experience of whoever is using them. Even professionals will wander out of range and in front of loudspeakers. Never be surprised by this.

3. Miking up the church PA is not likely to sound terribly good, but direct connection to church PA needs awareness of possible safety and ground loop problems. Always test this before the event with the PA switched on and mics at the ready. A lot depends on whether the church PA is operated during the event or just a passive preset system. If operated you need to check out the operator. I'd normally just double up with their mics for speed, ease and reliability.

4. Don't take on any more than you have to. If you are recording for a podcast be very wary of agreeing to feed a PA system for them.

5. Keep things as simple as possible and try to be unobtrusive at all times.
