Today I met with a vendor regarding the installation of a PA system at our facility. We currently record meetings with a handheld camcorder mounted on a tripod, and we're looking to add microphones in order to feed a clearer signal into the camcorder's audio-in jack directly from the mixer board.
This guy is supposed to know audio equipment, and at first he seemed knowledgeable until he made one statement that left me confused: he said that if we input an audio signal that is too high into our camcorder, the camcorder will stop recording video (i.e. the video will be either distorted or blanked out) until the audio levels are correctly adjusted.
Short of actually zapping circuitry inside the camera with an exceedingly high voltage and causing it to stop working, what on Earth is he talking about??? How could a high audio level affect the recorded video feed in any way?
Note also that he had no idea which camcorder we use because I never told or showed it to him. He was speaking in generic terms and applying this statement to all camcorders.
After he said this, I started seriously questioning if anything else he'd said could be taken seriously.
Any light to be shed on this?
