USING THE VIDEO/AUDIO SELECTOR
The VIDEO/AUDIO selector controls which parts of the input signal get used from any
given source.
You can set the VIDEO/AUDIO selector to any of three positions — VIDEO only,
AUDIO only, or both. Press the button as required to turn on the Video, Audio, or both
lights.
VIDEO – Video changes, audio does not.
AUDIO – Audio changes, video does not.
BOTH – Audio and Video both change.
Many sources (such as pre-recorded video tapes) carry both video and audio signals.
Other input sources (such as a compact disc player) carry only audio signals, and some
sources carry only video signals.
Example…
You are producing a documentary on hot air ballooning. You want to over-dub the video foot-
age of hot air balloons with a narrative audio track. Using the VIDEO/AUDIO selector you
can process only the video from the VCR and combine it with the audio from an audio tape
containing the voice-over material.
Procedure
To do this type of mixing:
1 Connect the VCR to one of the MXPro inputs on the rear panel – such as set num-
ber one.
2 Connect the audio tape deck to a different set of inputs – such as set number two.
3 Press CUT/A to select the VCR input.
4 Press the VIDEO/AUDIO selector until only the VIDEO light is on.
5 Press CUT/B to select the audio deck input.
6 Press the VIDEO/AUDIO selector until only the AUDIO light is on.
7 Press CUT/A to make it the CURRENT source, then press NEXT/B to make it the
NEXT source.
8 Start both input devices rolling.
9 Press PLAY to begin outputting the program.
Note
To designate any part of a signal with the VIDEO/AUDIO selector, an input device
must be set up accordingly. For example, to process only the audio signal from a video
tape in a VCR, the VCR’s audio output must be connected to MXPro’s audio input jacks.
See Chapter 3, Installing MXPro, and also see “Route” beginning on page 77.
