Anton/Bauer Wedge Mount Adapters instantly convert the Sony "wedge" connector, providing compatibility with all Gold Mount batteries. Although all Sony cameras feature a PowerTap connector, lighting is limited to either 25 or 50 watts (depending on model) due to current limiter in the camera. The wedge mount adapters allow the unrestricted use of on-camera lighting with the integral PowerTap connector, as well as access to the InterActive viewfinder Fuel Gauge and Automatique feature standard in all Sony camcorders. QR-DSR mounts instantly to the DSR series and DVCAM camcorders to adapt Anton/Bauer batteries. QR-A200 adapts the wedge mount on Sony DNW-A25/A220/A225/DS70 portable SX editing machines to the Anton/Bauer Gold Mount, because of the high current consumption of this machine, the HyTRON 120 is highly recommended. Can also be used to power Sony DSR50 VTR and BVMD9 high definition monitor.
