Calrec Modular I/O Rack (20 Slot)

Modular I/O boxes are 3U rack-mount enclosures with 20 I/O card slots that can be populated with a mixed range of I/O cards, allowing for a custom selection of I/O quantities and formats.

Modular I/O boxes connect to a Hydra2 network in the same way as Fixed Format I/O. Multiple modular I/O boxes can coexist on a Hydra2 network alongside fixed format I/O if required in order to make up the total quantity of I/O in the format and location it is needed.
