Plugging in Audio
Jack Audio Connectors
Some Blackmagic Converters have built in 1/4" jacks, so you can easily plug in balanced
external analog or digital AES/EBU audio. The 1/4" jacks are balanced TRS connectors.
TRS stands for Tip, Ring, Sleeve which refers to the three contacts of the jack connector.

The audio jack illustration on the previous page shows the jack connector’s positive,
negative and ground wiring pins. If you need to reverse the polarity of your analog audio
cable to suit your audio equipment, you can simply swap the positive and negative wiring
on the tip and ring pins.
NOTE
If you are connecting stereo analog audio, it’s worth mentioning that if you
reverse the polarity for one channel jack connector, make sure you do the same for the
second or your stereo analog audio will be out of phase.
