AUDIO CHANNEL SETUP
Move the cursor to Audio CH Set and press the “ENTER” button. The Audio CH setup window
will appear which is illustrated above.
There are four audio input channels, which can be used on any one of the 16 channels. Although
there are four audio input channels, you can only record one channel’s audio at a time, so for the
audio set you have to select one channel from the four in the Record Setup menu.
