Avid Pro Tools | MTRX base unit, currently racked and working. Includes power cable. No known issues.

Base unit includes:

• DigiLink Mini I/O — 2 ports, 64 channels to HDX/HD Native
• MADI I/O — 64 channels via coaxial BNC
• AES/EBU I/O — 16 channels via two DB25 connectors
• Pro|Mon 2 monitor control — mono through 9.1, plus up to 64-channel immersive formats; controllable via S6, EUCON surfaces, iPad, or DADman
• 1500x1500 matrix router
• 2U rack chassis

Additional cards installed:

• SPQ Speaker Processing card — 128 channels at 48kHz, 1,024 IIR filters (up to 16 per channel) for room correction and bass management, supports monitor formats up to 64-channel Dolby Atmos
• 64-Channel Dante card — up to 64 channels at 44.1kHz, scaling to 16 channels at 192kHz
• 128-Channel Dante card — up to 128 channels at 48kHz, up to 1,024 channels at lower sample rates, AES67-compatible
• DigiLink I/O card — adds 2x 32-channel mini-DigiLink ports (64 additional channels), enough to hang a second HDX or HD Native system off the same interface

No analog I/O or AD/DA conversion.

Two Dante cards installed means substantial combined Dante I/O capacity alongside MADI, AES, and DigiLink — a strong fit for a Dante-heavy or all-digital facility needing serious Atmos/immersive monitor control and routing.

Sold as-is. Everything above is accurate to the best of my knowledge, but I'm not a factory Avid technician and haven't bench-tested every port and function. Buyer is responsible for asking any verifying questions before the sale — happy to answer anything about configuration, history, or condition.
