Greetings,
MTRX is a modular and massively expandable (via chassis and 8 cards) 2U unit while MTRX Studio is a fixed configuration of IO. Both start with 64 Channels of DigiLink to interface with an HDX or HDN based system. Both can be configured for Stereo, 5.1, 7.1 or immersive monitoring with Dolby Atmos.
