Input selection

Switching is accomplished from within the Universal Switcher
Control Program by selecting which input to tie to one or both
outputs (see figure 4-3). The top row of inputs is available for
output 1 and the bottom row of inputs is available for output 2.
The same input can be routed to both outputs, but an output can
only be tied to a single input.
To tie an input to an output:
1. On the Universal Switcher Control Program main window,
click on the numbered input button you want to tie to each
output. Checkboxes control whether the switcher selects
video, audio, or both (system default is both video and
audio) and indicators (green for video and/or blue for
audio) will light to indicate your selection.
2. To switch the audio signal independently from the video
signal (audio breakaway) click the Video or Audio
checkbox as desired (the default is both boxes on).
Input selection from the switcher's front panel will cause the
program to "light" the associated indicators in the program to
reflect the change.

Muting the audio signals
To mute one or both of the switcher's outputs:
1. Click on the MUTE button for the selected output(s) on the
Universal Switcher Control Program main window (figure
4-3). An associated orange indicator will "light" to
indicate that the audio and/or video output is muted.
2. To unmute the audio signal, click the MUTE button again
to uncheck the audio mute for the selected output.
The MUTE function is not available from the switcher's front
panel and can only be achieved through RS-232 control. When
muted, the LED's for the muted inputs on the front panel will be
off.

window (figure 4-3) click on Configure.
