signal on an input, or to eliminate any undesired noise at the top or bottom of
a PAL or NTSC video source.
If your unit has an internal audio switcher / selector, this menu item selects
the desired Audio input for use with the active video source, allowing an
audio-follow-video function.
If an external audio switcher is connected via the OPTION bus, then this
menu item selects the desired Audio input for use with the active video
source, allowing an audio-follow-video function.
In most situations, the Audio input values would be different for each video
source – so that when the first video source is selected, so is the first audio
source (this is called ‘audio follow video’). The second video source then
selects the second audio source, etc. However, there is nothing to prevent all
Audio input values being set to the same value, for ‘audio breakaway’.
This menu item adjusts the audio volume and balance for the selected audio
channel. This is only functional for certain units when an optional Audio
Switcher is attached.
(This has replaced ‘De-glitch’ used on previous firmware versions.)
This option is used to tell the unit what to do if the video source is lost or
becomes unstable. Options are:
Option
Description
Show
Shows all picture break-up and instabilities.
Freeze
Freezes the latest frame – un-freezes as soon as the
source becomes stable again.
Blue (default)
Turns the window blue, to represent source loss.
Black
Turns the window black.
Remove
Removes the window, thus showing any background
(e.g. a Lock source). This is useful for MIX & PIP
scenarios on units with overlay abilities.
If you have a very unstable input, such as a video tape player with a poor
(jumping) output signal, you may wish to turn the setting to ‘Show’.
