When recording a live event where people are speaking, be sure to get quality audio. Most of the time the amateur video producer will rely strictly on the built-in microphone for getting audio while recording an event. Though this may be satisfactory for the family trip to Gettysburg, it will not give you acceptable audio for something like a wedding or church sermon. The best choice will always be to plug in directly to an audio board. If the church is large enough (usually if it has a consistent congregation of more than two-hundred and fifty people) it will have live sound mixing available. If that is the case, unplug the onboard microphone (if it has a built in microphone go into the system settings on your camera and disable it, then enable a foreign microphone input) and then use a standard XLR cable to run from the audio input on the camera to one of the audio outputs on the audio board. This way you will get only the audio that is coming through the location's speakers. What is great about being in a church with live audio is that the location is designed to be inclusive of all members of the congregation, so there are always reserved areas for those with hearing impairments. If you are worried that you are not hearing the exact audio that will be recorded you can plug headphones into the location provided for hearing impaired members. You will hear the exact output that is going through the audio board, and onto your recording.
