Using ATEM Software Control
Using the Audio Mixer
The audio tab is used to mix audio sources connected to the ATEM 2 M/E Production Switcher via HDMI,
SDI, external audio and from the built-in media players.
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. The monitor fader and checkboxes appear below the master fader and set independent audio
levels and allow solo monitoring on the audio breakout cable output.
The checkboxes below each audio level meter determine whether audio is always available for mixing or
only when the source is on air and also whether the audio source should be used for solo audio monitoring
on the audio breakout cable.
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.
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.
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 and will usually
change over time. A green number represents low to medium audio levels. A red number corresponds with
an audio level in the red part of the audio meter. 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.
