Connecting other Audio Sources
All ATEM production switchers feature standard balanced XLR or TRS audio inputs and outputs.
TRS connectors are also known as 1/4 inch jacks. XLR and TRS inputs are balanced, designed
to reduce interference and noise, especially when long cable lengths are required.
If your ATEM switcher has unbalanced RCA audio inputs, you can connect your external audio
source directly. RCA audio connectors are useful when using audio from consumer equipment
such as a HiFi system or iPod.

Using Embedded SDI and HDMI Audio Sources
All ATEM switchers include a built-in audio mixer that lets you use the embedded HDMI and
SDIaudio 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. You don’t need an external audio mixer unless you prefer
to use one.
