Radial Engineering Catapult RX4 4-Channel Audio/AES Receiver – Cat5/6 Signal Recovery Interface for Balanced Analog and Digital Audio Distribution Systems

The Radial Engineering Catapult RX4 4-Channel Audio/AES Receiver is a professional Cat 5/6 signal recovery interface designed to convert transmitted audio back into standard balanced outputs for use in studio, live sound, broadcast, and installation systems.

As the receiving half of the Radial Catapult system, the RX4 takes up to four channels of audio or AES/EBU digital signals sent over a single shielded Cat 5, Cat 5e, or Cat 6 cable, and converts them back into discrete, balanced analog or digital outputs. This allows seamless long-distance signal distribution while maintaining clarity, headroom, and low-noise performance.

The RX4 is designed to work with compatible Catapult transmitters, enabling flexible system configurations for both line-level and digital audio routing. It is equally suited for transporting signals between stage and front-of-house, linking studio rooms, or simplifying complex installation wiring.

Built for professional reliability, the unit features a rugged metal chassis and stage-ready connectors, ensuring stable operation in touring, broadcast, and fixed installation environments. Its design focuses on preserving signal integrity while reducing the need for heavy, multi-core analog cabling.
