The MTRX solves a major problem in pro audio: syncing digital and analog formats to work seamlessly together. The unit delivers pristine sound quality with extensive monitoring and routing capabilities in a versatile audio interface for Pro Tools HDX, HD Native, and other pro audio applications. With MTRX, you gain the superior sonic quality of Digital Audio Denmark’s (DAD’s) legendary analog-to-digital converters, plus flexible routing and monitor control when used as a standalone device or with Avid Pro Mixing surfaces. And because the interface can be customized with all the analog and digital I/O you need, you can take on the most demanding music and post-production challenges. Effortlessly.

Achieve Exceptional Sound
Digital Audio Denmark’s AD and DA converters are renowned for delivering the cleanest, most transparent, and highly detailed sound. By incorporating these converters, Pro Tools | MTRX enables you to get the best sound quality possible from your Pro Tools | HD system—up to 384 kHz DSD. And because it does double duty as both an audio I/O and monitor interface, it offers exceptional versatility too.
