Example…
You are producing a documentary on hot air ballooning. You want to over-dub the video
footage 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.
To do this type of mixing:
1 Connect the VCR to one of the MX-4 inputs on the rear panel, such as set number 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
/

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 the MX-4’s audio input jacks. Refer to Chapter 3, Installing the
MX-4 and also refer to “Route” on page 73.
