The DiGiCo SD-Rack is a high-performance, modular 14-slot input/output rack designed for professional live sound, touring, broadcast, and installation applications. Built on the same Stealth FPGA technology as DiGiCo's renowned SD-Range consoles (e.g., SD7, SD5), it delivers exceptional audio quality with support for up to 192 kHz sample rates and flexible digital formats. It's rugged for touring, with hot-swappable components and redundancy, making it ideal for large-scale productions where reliable remote I/O is essential. Up to 14 SD-Racks can operate on a single optical loop, or 28 on a dual loop, supporting multi-console setups.
