working with audio inputs and tentacles

10.99K viewsHardwarequestion

Am thinking that tentacles can help with my situation, so have a question before buying them.

I film some medical surgeries and also medical conferences. I think the tentacles can work well for our situation, is there a way to work with external audio at the same time?

For instance, in the conferences, we have 2 cameras on gimbals that we walk around with getting footage. These sync up with 5 feeds from AJA Ki pros from the main presentation. I would like to be able to sync the 2 roaming cameras to the main feeds, but I also need audio coming in from the roaming cameras. We have been using small shotgun mics plugged into the cameras for when we interview participants during breaks etc.

So, is there any way to input external audio and use the tentacle at the same time. I am trying to avoid putting audio recorders on each rig as well.


Hi Eric,

what types of cameras do you use on the gimbals?

Basically it is no problem to record TC on one channel and audio from a shotgun on the other.

Best, Max


I use Nikon d810’s and d750’s and sometimes a canon 5dmiii.

How do you plug both devices into the cams when there is only 1 mic input?

thank you for the info, look forward to hopefully making all this work!


You can just use an ordinary y-adapter (mono left / mono right -> stereo connector) like this:


I would expect some timecode bleed from the tentacles onto the audio channel of the D810. I would not record serious audio on a DSLR camera together with timecode. I have a D810 here too, so i know. I know you are avoiding it, but better put a separate audio recorder on the camera like the Tascam DR-701D, it has timecode too. And give the other units a Tentacle.
