Your Vows and Music are recorded with three industry known Sennhauser lavaliere mics. These are pencil eraser size mics that clip on the pastor, groom and singer's lapel, (they produce very good rich tones). All three cameras have back-up mics as well. You can rest assured that your vows will be heard with full rich clarity with a minimum of echo. Amateur cameras don't have near that ability. So what you will experience with amateur cameras is a low mumbling echo sound.
