DiGiCo Little Blue Box allows you to share a D-Rack between two or three consoles.
Be it for simple outdoor festival stage striking, or sophisticated multitrack live recording, LBB is a handy addition to any DiGiCo digital mixing solution.
The SD9 / MADI switch allows you to select between the SD9 (or SD11), or whatever console is plugged in to the MADI connector to control the D-Rack.
The 'Console RX. auxiliary output' is designed to be the redundant run on an SD8 or SD7. Alternatively, it could be split off to another console with one SD9 (or SD11) using a CAT5 connection and one MADI pair for the SD8, which could then feed off to a recorder or another console.
LBB is poweredd via USB, with a second USB port acting as a thru.
