AJA Hardware Audio
NOTE: Linux OS has not yet been tested with this functionality and as such remains
unsupported until a future announcement.
To control which AJA hardware audio is used during recording, you use the
Control Panel application's Input Select Screen, Audio Input Select drop down to
select from
• SDI embedded
• HDMI embedded
• Analog (via DB25 cable)
Any level adjustments to Capture or Audio Punch In / Voice Over to Timeline
recording operations will either need to be made upstream of the AJA input, or
else via adjustments within the main NLE application (e.g. via a pass through mix
tool).

The Io 4K in 4K Mode Control Panel screens that are significantly different from
the Io XT screens previously described are presented below.

UltraHD/4K 4-wire Source on the Input Select menu, four connectors are used
receive the signal to process. UltraHD signals report their links as 1080. No SDI
