If you are operating a 2 M/E or 4 M/E
ATEM switcher, and notice the solo and
monitor settings are grayed out, you have
program audio selected for the audio
out setting in the settings window.
The audio meter for Cam1 is shown in gray
to indicate that its audio will not be used as
neither of its ON or AFV buttons are enabled.
Cam2 has AFV selected but its audio is not
currently being used as the camera is not on
air as is indicated by its dull yellow tally light.
Cam4 and Cam7 have their direct mix set to
ON so their mixed audio is always used, and
their tally lights remain lit, even if another
camera is currently on air. The audio level
meters for Cam3, Cam5, Cam6 and Cam8 show
that no audio is present on these cameras.
Audio Source Selection
Below each audio level meter, you will find the ON and AFV buttons that select which audio
sources are sent to the program output of the switcher.
ON
Selecting the direct mix to ON allows an audio input to be permanently mixed into the program
output, even when the associated video source is not on air. The red tally light will always be lit
because the audio is always on air. Selecting this option automatically disables AFV.
AFV
Audio-follow-video (AFV) allows audio to crossfade when inputs change. The audio will only be
sent to the program output when the input is on air, lighting the red tally light above. When off
air, the tally light is lit dull yellow. Selecting this option automatically disables the direct mix ON
setting.
SOLO
ATEM Production Studio switchers and ATEM Broadcast Studio switchers can use the XLR audio
output via the switcher’s rear panel.
Selecting solo exclusively outputs that single audio source to the monitor output so you can
listen clearly to any single input when required. This is an important feature which lets you
confirm audio content before putting it to air and without affecting the program output audio.
When solo is deselected the audio output will return to its original state.
