Sony FX3 Audio TC recorded on channel 2 (via XLR) Sync Studio doesn’t find Audio TC

Hi,

We recorded the signal from our Tentacle Sync E via XLR (audio handle) on the audio channel 2 of our Sony FX3 (Channel 1 was camera mic). Unfortunately Tentacle Sync Studio can’t find the signal on the audio track and says “No Audio Timecode found”.

Is there any solution or workaround to this problem?

I have seen some similar question on this issue with the FS7, but found no answer.

If there is any explanation, I would appreciate your answer.

Thanks in advance!
