Using Audio
Connecting other Audio Sources
Your ATEM switcher features standard balanced XLR audio inputs and outputs so you can
connect your external audio source directly. The XLR inputs are balanced and designed to
reduce interference and noise, especially when long cable lengths are required.
Balanced XLR inputs let you connect external analog audio
Using Embedded SDI and HDMI Audio Sources
Your ATEM switcher includes a built-in audio mixer that lets you use the embedded HDMI and
SDI audio from your cameras, media servers and other inputs without the need for an external
audio mixer.
Once you’ve connected your SDI and HDMI cameras to the switcher for vision mixing, there are
no other connections to make as the audio mixer uses the embedded audio in the video signal.
This saves space and makes setup very fast and low cost as you don’t need separate audio
connections for every video source, and you don’t need an external audio mixer unless you
prefer to use one.
The audio is mixed using the control buttons and knobs on your switcher, or via the Audio tab
of ATEM Software Control and output over the SDI and HDMI program outputs as embedded
digital audio.
