The SBAC-US10 USB Reader/Writer supports those with PCs not equipped with the Express Card slot. The SBAC-US10 can be connected to a Windows PC or a Macintosh via USB interface. Since this connection is made as “Mass Storage Class”, no special driver installation is required. DC power must be provided using the supplied AC adaptor. The reader allows for capturing of your XDCAM EX footage without tying up your camcorder, saving you time during your shoot.
