The Remote Audio BDSCT4F cable is used to connect the Remote Audio BDS to any piece of gear that uses a TA4 input for powering, including the Sound Devices 888, Scorpio, and 833 mixers. The 2' cable features a BDS (5.5 x 2.5 x 12mm) RA coaxial plug to connect to the BDS at one end, while the other end sports a TA4F connector for the mixer or similar compatible equipment.
