Fail Safe Alternate SDI inputs
Some Blackmagic Converter models include alternative SDI inputs for redundancy.
Theseinputs are labeled ‘Alt SDI In’ and will immediately take over should the primary SDI input
signal fail. In this rare scenario, the SDI LOCK LED will flash, indicating that the converter has
switched to the ALT SDI input.
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.
Below is an illustration showing the wiring pins inside the male 1/4” jack connector if you want
to make your own audio cables.
