This ARRI EDB-2 EXT Sync Distribution Box is a sync breakout-box for the ALEXA Mini camera, featuring three EXT output ports. Designed for use in VFX, 3D, and VR setups, multiple EDB-2 units can be employed to link up to 15 ALEXA Mini cameras. Set camera functions such as frame rate, shutter speed, and ND strength on your master camera, then sync the slaved cameras; all units will then operate as if they are a single camera.
ALEXA Mini EXT to EXT cables are used to link the cameras and sync boxes. Software Update Package (SUP) 5.0 or higher is required to use the ALEXA Mini's EXT sync function.
