ABSTRACT
Successful audio is a blend of two things: appropriate techniques and appropriate artistic choices. Both techniques and artistic choices are largely a matter of technical knowledge combined with experience. Unlike automatic control circuits, audio personnel are able to anticipate and make artistic judgments, which can make the final audio far superior. The drawback to manual control is that the audio personnel need to be vigilant all the time, ready to make any necessary readjustments. An audio mixer is needed whenever there are a number of sound sources to select, blend together, and control. Larger audio mixers include a cue circuit, which enables audio personnel to listen privately on earphones or a loudspeaker to the output of any individual channel, even when its pot is faded out. If the camera is fitted with a microphone, the theory is that when it is aimed at the subject to capture the video, the mic will also pick up quality audio.
