Using ATEM Software Control

Using the Audio Mixer
The audio tab is used to mix audio sources connected to any ATEM switcher via HDMI, SDI, external audio
and also from the built-in media players in ATEM 1 M/E and 2 M/E Production Switcher models.
Cameras, media players and external audio sources are listed along the top of the audio mixer along with
the master audio output for the program outputs of the switcher.
Below each audio source is an audio level meter, a fader for setting the maximum audio level, and a
crossfader for setting the left/right audio channel balance. The master fader on the right side of the audio
mixer is used to set the gain on the audio level on the SDI and HDMI program outputs and has its own
audio level meter. On all ATEM switcher models except for the ATEM Television Studio, the monitor fader
and checkboxes appear below the master fader and set independent audio levels and also allow solo
monitoring on the audio outputs.
The checkboxes below each audio level meter determine whether audio is always available for mixing
or only when the source is on air. On ATEM Switchers, excluding Television Studio, the solo checkbox
determines whether the audio source should be used for solo audio monitoring via the switcher chassis or
audio breakout cable. If you notice the solo and monitor settings are grayed out, you either have an ATEM
Television Studio or program audio is selected for the audio breakout setting in the settings tab.
Tally
Any source whose audio is on air is lit with a red tally light in the software. External audio is on air by default
so the EXT tally light is usually lit red. In the example on this page, Cam4 and Cam7 are lit because their
audio is set to be always on.
Audio Level
Drag the audio level fader to set the gain on the audio level for each camera and audio source. The green
number under each audio level meter shows the maximum audio level set by the fader.
The number above the audio meter shows the peak audio level reached by the audio source. A green
number represents low to medium audio levels. If the audio meter is regularly showing red, and the red
number above it is not changing, then you should reduce the audio level to avoid audio distortion. After
adjusting the audio level, you may wish to reset the red number by clicking on it once. Observe the new
number to make sure it changes for a while and does not immediately shoot up and become stuck on a red
number. If it does, you may need to reduce the audio level even further.
Audio Balance
The audio mixer supports stereo audio from each audio source. If you wish to change the left/right audio
channel balance for a camera or other audio source, slide the crossfader to the desired balance point.
The audio mixer displays red tally lights for any audio sources
that are currently on air, as well as audio level, audio balance and
checkboxes for selecting which audio should be used.
If you are operating an ATEM switcher, excluding Television
Studio,
and notice the solo and monitor settings are grayed out,
you have program audio selected for the audio out setting in the
settings tab. The solo and monitor settings are always grayed out
on ATEM Television Studio.
