Thanks a lot for your answer Bob
I had missed the AES-EBU input in the specs.
Concerning the sync, I guess my questions wasn’t precise enough : as far as I knew, synchronized HDMI inputs is something very new that allows for the first time a cheap mixer to mix consumer cameras signals. So I wondered how well it works.
Would you confirm that it works as well as with genlocked cams ?
Thanks a lot for your help
