The CV-FX9 mounts directly to the back of the Sony PXW-FX9, as an alternative power option to the Sony XDCA-FX9. The milled aluminum product inserts into the battery slot of the camera and also attaches into the top of the camera(with included screw hardware) to provide a secure platform for mounting v-mount batteries directly onto the FX9 camera. It has a 19.5v DC output with a visual low battery warning LED and a 4-pin XLR DC input for hotswapping between external and on-board power. In addition, it’s equipped with two powertaps to power additional accessories and three 1/4-20 threads on the top to attach accessories. A USB firmware update port on the rear ensures future compatibility with camera firmware updates.
A BP-U30 or BP-U35 battery pack fits inside of the battery cavity on the camera, allowing the user to hotswap batteries. Once the v-mount on-board pack dies, it will automatically pull power from the BP-U30 and you will see the battery indication on the viewfinder change. To make it easier to take the CXV-FX9 plate on-and-off, M4-8mm thumbscrews can be purchased separately.
