Hello Yeshin.
If your post size is 1.5", you can adapt the volt to your post. (I own an Artemis 1.5" and everithing was ok)
You should buy the VOLT GK1 kit from Tiffen. This Kit comes with the docking bracket, control box, power and gimbal cables, gimbal and its adapters for the 1.5" post ( in addition to other post measurements)
The control box is powered at 12V.
I don't know what power cable you use from your movcam, but I think that Tiffen DOES NOT make cables that are not compatible with Pro or Tiffen.
Find out carefully so as not to burn the control box.
You have to let Tiffen know if you are Regular or Goofy and they will send you the kit according to your order.
I hope the help has been helpful.
Hugs, Gus
