The XDCU-50 Camera Extension Unit is part of Sony’s camera extension system which enables Sony XDCAM EX camcorders, with their well-established reputation for high quality, full HD pictures, to be configured for studio operation. This new system consists of a pair of camera adaptors, the XDCA-53 and XDCA-55, and the XDCU-50, which controls camera parameters via one of Sony’s compatible optional remote controllers. Using a pair of BNC cables, the camera signal and return signal can be transferred up to 100 meters (328 feet) without degradation between the XDCA-53 or XDCA-55, and the XDCU-50. The system offers an affordable solution for people who prioritize the versatility of each camcorder in either stand-alone or multi-camera operation.Both the XDCA-55 and XDCA-53 connect to the XDCU-50 camera extension unit via two BNC cables (not supplied - one for the camera signal, the other for the return signal). Additionally, a CCZ-A cable (sold separately – up to 100m) is required from the XDCU-50 to supply power to the XDCA-53 or XDCA-55. The camera signal and return signal can be transferred up to 100 meters (328 feet) without degradation. The system offers an affordable solution for people that require maximum versatility of each camcorder in either stand-alone or multi-camera operation.
