The D-Box for ARRI ALEXA Mini/Mini LF (V-Mount) runs the camera from a single V-Mount battery while adding power distribution, a run/stop function and hot-swap battery capability. A 4-pin mini-XLR port passes through backup AC power during a battery swap, so the camera and its accessories stay powered through the change. It can drive up to four ports simultaneously, at up to 3A per output and up to 10A total draw, through one 7-pin EXT port and two 2-pin 12V LEMO ports, plus two 3-pin 24V Fischer ports carrying the run/stop signal. Integrated 16" cables connect directly to the ALEXA Mini/Mini LF's 8-pin LEMO-type power input and 7-pin LEMO-type EXT port. The distribution/breakout box mounts on Wooden Camera 15mm or 19mm rod brackets or battery slides, or directly to the ARRI BAP-1, for a fit into ALEXA Mini rigs of any configuration.
