SQ MADI provides any SQ mixer with a 64×64 MADI interface running at either 48kHz or 96kHz. Two BNC inputs pair with two BNC outputs to allow for split or redundant setups while a dual function (in/out) BNC Wordclock connection enables the console to sync with other equipment.

SQ MADI enables connection and synchronisation with broadcast or recording systems, OB vans, and third-party consoles for high-channel count feeds over coaxial cables.
