The CXV-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. A USB firmware update port on the rear ensures future compatibility with camera firmware updates.
