Hello, I video weddings using 3 camcorders on the beach. I have some wireless lapel mics by azden. The sound is muddy almost overmodulating . I leave the audio input on auto on the camcorders. I'm not a tight wad so tell me how to find some wireless lapel mics that would rival my camcorder built in condenser mics. I'm looking for a sweet bright sound. Mine azdens sound like someone being smothered with a pillow.
