Another day, another circus Session this time we were learning about location sound. this is what i wrote about it for my Circus Report:
Locations sound works hand in hand with location camera’s providing additional sound capabilities to the single camera, for example an interview situation that required two personal mic’s could be mixed together before being fed to the camera as stereo or mono line level mix. Location mixers often have 2-4 inputs and can either mix in stereo or dual mono. Location mixers normally have better Microphone pre-amps than Camera’s, which in turn provides better sound quality, as the mixer is outputting at line level (0db) and the camera won’t apply any more amplification to the signal.
Some microphones require batteries or phantom power (+48v) to operate; these mic’s are a form of capacitor mic’s are much more sensitive than standard dynamic mic’s that don’t require power to operate. Most cameras and mixers can supply phantom power to these microphones.
When setting up for a shoot, you can use the tone that the mixer is supplying to the camera to help setup the record levels on the camera. Tone should be set just below the 0db mark as this allows some “head room” before the camera starts to clip the signal should you go above the tone volume.
