Q-SYS CAES4 4-Channel AES-3 Digital I/O Card for Q-SYS Core

The Q-SYS CAES4 is an AES-3 digital audio I/O expansion card designed for installation directly into Q-SYS Core processors. It is the right tool for systems integrators and AV engineers who need to extend their Core's digital connectivity without introducing analog conversion stages into the signal chain. Typical deployment scenarios include installed sound systems, broadcast facilities, and conference room infrastructures where source devices or amplifiers with AES-3 interfaces must connect cleanly to the Q-SYS ecosystem.

What separates the CAES4 from generic breakout alternatives is its native integration with the Q-SYS platform. Because the card slots directly into a supported Core, it leverages the processor's existing routing, mixing, and control logic without requiring external converters or additional rack space. The pair-configurable channel design gives integrators precise control over how each pair of channels is directed, making the card practical for asymmetric signal flows where more inputs than outputs, or the reverse, are needed at a given I/O point. For teams building scalable, maintainable installed audio systems on Q-SYS hardware, the CAES4 delivers targeted AES-3 expansion with zero compromise to signal integrity.
