Looking for a way to use the internal mic reference audio on a cinema camera

I was wondering if there’s a way to get the reference audio from the internal mic on a Tentacle Sync going into an Arri Alexa?


In the manual it says: Using the built in microphone is only possible when working at mic levels with plugin power switched on at camera side.


I’m not sure exactly what this means, but I’m assuming it just needs to receive power externally? I suppose generally it wouldn’t work on a camera like the Alexa, but if I had it hooked up to a mobile USB battery pack, would that allow me to use the mic?


What is the advantage of using the poor quality build in mic of the Tentacle together with a USB powerback and all the cable splitters above a simple camera mic?
