Using Audio
Connecting other Audio Sources
All ATEM switchers except ATEM Television Studio and Production Switcher models feature
standard balanced XLR audio inputs and outputs, and unbalanced RCA audio inputs so 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. The XLR inputs are balanced and
designed to reduce interference and noise, especially when long cable lengths are required.
ATEM Television Studio has an AES/EBU digital audio input
If you’re using an ATEM Television Studio with an external digital audio source, such as a digital
microphone or mixer, you can connect the AES/EBU audio output of the source directly to the
AES/EBU IN port on the switcher. Otherwise, you can use an inexpensive A/D converter to
convert the analog audio output of your audio source to AES/EBU audio for your switcher.
If you have an ATEM 1 M/E or 2 M/E Production Switcher, you can use the included breakout
cable or make your own custom breakout cable to connect your external audio source’s
professional, balanced, analog audio output to the switcher.
ATEM 1 M/E and 2 M/E Production Switchers have an audio in/out
port which connects to an analog audio breakout cable.
Unique to ATEM 2 M/E Broadcast Studio 4K and ATEM 2 M/E Production Studio 4K are line
level, balanced XLR input and output for talkback, designed for connecting to existing talkback
systems. This model also features XLR input and output for timecode. Standard SMPTE linear
timecode is supported and the output is frame synchronized for reliable video and audio timing.
