AVID 9900-71257-00 Dual MADI I/O Card without SFP for MTRX

Dual MADI Expansion for Pro Tools MTRX with Modular SFP Flexibility
The AVID 9900-71257-00 MTRX Dual MADI I/O Card is a full-length PCIe expansion module for the Pro Tools | MTRX base unit, designed to deliver up to 128 channels of bi-directional MADI connectivity. Outfitted with two empty SFP cages, this card gives you the flexibility to configure your I/O with either optical LC or coaxial mini-BNC SFP transceivers, depending on the demands of your studio, live rig, or broadcast infrastructure. It’s a powerful solution for scaling up digital audio routing without sacrificing expansion real estate for other analog or digital formats.

Add 128 Channels of MADI to MTRX with Modular SFP Support
This dual-port card supports two 64-channel MADI streams, allowing you to route high channel counts in and out of the MTRX over fiber or coax. Because the SFP transceivers are not fixed, you can select the optical or coaxial interface that fits your current system architecture or change them later as your setup evolves. Whether you're connecting to large-format consoles, routers, or MADI-enabled converters, this card delivers efficient and customizable digital audio transmission.

Modular Design with Empty SFP Cages for Custom Configuration
Unlike fixed-connector MADI cards, this module includes two open SFP slots, enabling the use of user-selected small form-factor plug-in transceivers. You can install SFPs tailored to your desired wavelength, signal format, or connector type—whether that's LC fiber for optical MADI runs or mini-BNC for coaxial systems. This modularity makes the card adaptable to both existing infrastructure and future upgrades.

Maximize Expansion Slot Efficiency in MTRX Systems
By consolidating 128 channels of MADI into one dual-port card, this I/O module helps preserve valuable expansion slots in your MTRX base unit. That leaves more room for other cards such as AD, DA, AES, or Dante modules, enabling you to fully customize your system without compromise. The card’s connector placement within the MTRX ensures easy access and integration, appearing in the optical I/O section above the DigiLink ports.

Ideal for High-Density Audio Routing in Broadcast and Studio Environments
This module is a smart choice for facilities managing multiple MADI streams, especially where space, channel count, and cable type flexibility matter. Whether you're working in a post-production suite, large-scale recording facility, or live broadcast control room, the dual MADI card provides the scalable I/O capacity required to manage complex routing scenarios and integrate seamlessly into fiber or coax-based MADI infrastructures.

Supports Lucent Connector (LC) or Mini-BNC Interfaces
Depending on the installed SFP modules, this card supports LC optical MADI connections or mini-BNC coaxial MADI links. That makes it compatible with a wide range of gear across different formats. It’s especially helpful when transitioning between fiber and coax installations or when integrating systems that use both types of connectors across different signal paths.
