1) Most professional boards will have XLRs. However, it might have a 1/4″ jack. Check with the PA person to find out or bring a phone plug to XLR adapter. If it is a phone plug make sure it’s a balanced connection or you might pick up hum.
2) It’s most likely line level. But, ask the board op to be sure. After you have hooked up the feed to your camera with line inputs selected, if you hear no or very low audio, it may be mic level. Then, switch the inputs to mic level and see what you have. If you still have a problem, it’s probably the cable.
In any case, always record some audio and play it back and listen carefully. During the ceremony, it will be too late to make major adjustments. Request some kind of sound check. I can’t believe the people handling the PA won’t be doing checks. Be there when they do, record their sound check and make sure your audio is good.
Again, if you can find a more experienced audio person, even if only to help with the hook up, it might save you a lot of trouble.
