Pro Tools | MTRX features eight pairs of AES/EBU I/O, 64 channels of DigiLink I/O, and 64 channels of MADI I/O in the base unit to get you started, but otherwise comes “empty.” This enables you to completely customize the audio interface with up to eight option cards for your unique music and/or audio post workflow needs.

You can mix and match up to six analog I/O cards to support up to 48 analog channels per MTRX interface, design an all-digital box with up to eight digital I/O cards (supporting up to 1,088 Dante channels or 1,216 MADI channels when maxed out with all available cards and modules), or configure it with any combination of analog and digital I/O. And if you’re mixing Dolby Atmos or other immersive audio format, the SPQ Speaker Processing Card will optimize your monitoring experience.
