4.2.3. Displaying the Status of Input Video Embedded Audio Groups
The 7707MT-HD allows the user to monitor the status of input video embedded audio groups. This allows
conflicts to be identified and resolved. To view the current status of input video embedded audio groups,
select the STAT (Status) menu item in menu level 1, followed by the VIN (Video Input) and GRP1, GRP2,
GRP3 or GRP4 (Audio Groups 1 through 4) menu items.

4.2.4. Displaying the AES Audio Sample Rate
The 7707MT-HD can detect the sample rate of valid AES input audio on each channel, which can be
reported to the display. To indicate the AES input sample rate, select the STAT (Status) menu item in
menu level 1, followed by the AIN1, AIN2, AIN3, or AIN4 (Audio Input 1 through 4) menu item. The
following list describes possible Audio Sample Rate indications:
