Set 3G SDI Output Level
If you're outputting HD video to equipment with 3G-SDI inputs, you may need to toggle
between level A and B 3G-SDI output standards to maintain compatibility with equipment that
can only accept level A or B 3G-SDI video. Level B is the default setting that works with most
equipment, but you can switch to Level A by clicking the 'level A' radio button.
Setting 3G-SDI Output Level
Setting the Audio Output Behavior
The 'audio' tab lets you control the audio monitoring settings, such as selecting the program
audio or monitor audio via the XLR outputs. Instead of XLR monitor outputs on
ATEM Constellation 8K, you can use the MADI out BNC connectors.
Program audio is the same audio that the audio mixer sends to the SDI and HDMI program
outputs. Monitor settings and solo monitoring are disabled in the audio mixer when program
audio is selected.
Monitor audio allows you to listen to the program audio mix of all inputs, or just a solo input,
at your preferred volume level and without affecting the audio on the program output. You can
monitor the solo audio source even if it is not on air.
These monitor settings are only available to the audio mixer when monitor audio is selected for
the audio out setting in the settings window.

SDI Audio Channels 15 and 16
You may want to loop one of your ATEM's outputs to an input to achieve a desired effect.
In some cases this can cause a feedback loop in SDI audio channels 15 and 16. If this occurs,
you can mute SDI channels 15 and 16 by clicking the 'mute' checkbox in the audio options
located in the general switcher settings.
Talkback on ATEM Constellation 8K is embedded in SDI channel 13, 14, 15 and 16.
If you're using Blackmagic Design products for talkback, such as ATEM Talkback Converter 4K
and ATEM Camera Converters, muting SDI channels 15 and 16 from your switcher will not affect
talkback functionality.
Mix Minus Settings
The mix minus settings on SDI outputs let you mute the audio from their return program feed.
For example, when doing live crosses there can be a delay in the audio which may be
distracting when the presenter can hear his or her own voice delayed on the program return
feed. Enabling mix minus for an input will output all program audio in the mix, minus that
particular input.
