Figure 3-4 — Audio ties
• Video and audio ties between the low resolution video input group and the
low resolution video output group are always made with the audio redirected.
In such an operation, the switcher automatically ties the audio to an output
in the computer video/audio outputs group (outputs 1 through 6) as follows:

If the video is tied to output 7, the audio is tied to output 1.

If the video is tied to output 8, the audio is tied to output 2.

If the video is tied to output 9, the audio is tied to output 3.

If the video is tied to output 10, the audio is tied to output 4.

If the video is tied to output 11, the audio is tied to output 5.

If the video is tied to output 12, the audio is tied to output 6.
• If video is selected for configuration (the Video LED is lit) and you press the
input button for an input in one group and then try to select an output in the
other group, the associated output button cannot be selected. The associated
input LED remains lit.
• Audio from the mic group cannot be selected from the front panel. Audio in
this group can be selected only under serial port or Ethernet control.
• Only one video input and one audio input can be tied to an output.
• If a tie is made between an input and an output, and the selected output was
previously tied to another input, the older tie is broken in favor of the newer
tie.
• If an input with no tie is selected, only that input’s button lights.
• When the Video button and Audio button are lit, if an input with an audio
tie but no video tie is selected, the output button lights the appropriate color
(amber, green, or red).
• As each input and output is selected, the associated output button blinks the
appropriate color to indicate a tentative tie. Buttons for output(s) that were
already tied to the input light the appropriate color steadily. Outputs that are
already tied can be left on, along with new blinking selections, or toggled off
by pressing the associated output button.
