Allen & Heath SQ MADI Card for SQ & AHM

Allen & Heath SQ MADI Audio Interface Card

The Allen & Heath SQ MADI is a professional MADI expansion card designed for SQ series digital mixers and AHM matrix processors. The card provides a high-capacity 64×64 channel MADI interface, enabling seamless integration with broadcast facilities, recording systems, OB vans, audio routers, and third-party digital consoles using industry-standard MADI connectivity.

Supporting operation at both 48kHz and 96kHz sample rates, the SQ MADI card delivers flexible deployment across a wide range of professional audio environments. Users can select between standard 48kHz operation or high-resolution 96kHz workflows, ensuring compatibility with existing infrastructure while maintaining excellent audio quality and reliable signal transport.

The interface utilizes dual MADI links through four BNC connectors, allowing up to 64 channels of bidirectional digital audio routing. The dual-link architecture supports split and redundant configurations, providing enhanced reliability for mission-critical broadcast, live production, and recording applications. This redundancy capability helps maintain uninterrupted audio transmission in demanding environments where system stability is essential.

A dedicated Wordclock BNC connection enables precise synchronization with external equipment. The console can operate as either the master or slave clock source, simplifying integration into complex digital audio systems. Additional features such as console-controlled error handling and support for both Smux and High-Speed 96kHz modes further enhance operational flexibility and reliability.

Designed to expand the connectivity capabilities of SQ mixers and AHM processors, the SQ MADI card offers a practical solution for high-channel-count audio transport over coaxial cable infrastructure. Whether deployed in broadcast studios, live production systems, recording facilities, or mobile production units, the SQ MADI delivers dependable performance and professional-grade digital audio integration.
