Tentacle Sync E, and Canon XC10

Hi,

I recently bought a tentacle sync E, and I would like to use it on my Canon XC10. However, I can only get one channel of sound, namely the timecode channel, the microphone channel seems not to give any signal. My setup will allow me not to use the scratch audio from the tentacle sync E, but the scratch audio would provide me with one more way of syncing if for some reason the timecode would not work.

Best regards, Johan
