The DiGiCo X-D5T-RE is a dedicated, stand-alone hardware unit engineered to provide comprehensive system redundancy for DiGiCo digital mixing consoles and their associated audio networks. Its primary function is to create a fault-tolerant audio path by simultaneously receiving two identical streams of digital audio—typically the primary and backup feeds from a DiGiCo console or system—and automatically switching to the backup in the event of a failure in the primary stream. This is critical for live broadcast, major touring, and high-profile events where any interruption in audio is unacceptable. The unit monitors the health of both incoming digital audio feeds in real-time, checking for loss of signal, excessive errors, or loss of word clock, and performs a seamless, glitch-free switch to the healthy stream, often in a matter of microseconds.

The redundancy engine is designed to be inserted at a key point in the signal chain, such as between a DiGiCo console and a broadcast transmission encoder, a recording system, or the main PA drive system. It supports industry-standard digital audio formats, commonly including AES3, AES3id, and MADI (via optical or coaxial connections), making it versatile for various system architectures. Configuration and monitoring are facilitated through a front-panel display and controls, allowing engineers to set switching priorities, hysteresis (to prevent rapid toggling on a marginal signal), and view the real-time status of both inputs and the active output.

Built as a robust, rack-mountable unit, the X-D5T-RE features dual redundant power supplies to ensure its own operational reliability. It acts as an insurance policy for the entire digital audio output of a system, providing peace of mind and technical assurance. By offering automatic, transparent failover protection, the DiGiCo X-D5T-RE is an essential component for any mission-critical audio application where system resilience and uninterrupted audio delivery are paramount.
