Powering your Sony PXW-X160 or X180 camera from a Protech ST-7R/RS rig merely requires that you use the DC Power Cable for ST-7R Shoulder Rig Adapter to Sony PXW-X160/X180. Mount your camera on the shoulder rig adapter, connect the cable from the shoulder rig to your camera, power the shoulder rig, and you are ready to shoot ENG-style with your camera. This 23" long cable features a locking mini 4-pin connector that attaches to the ST-7R/7RS on one end, and a barrel connector on the other that delivers the required 19.5 VDC to your camera.
