Safe and secure checkout
The Radial Catapult TX4 is a passive 4-channel audio snake transmitter that allows you to send analog or AES digital audio over standard Cat 5 or Cat 6 shielded twisted-pair cable. Designed for flexible signal routing in live sound, broadcast, and studio environments, the TX4 replaces traditional bulky multi-core snakes with a cost-effective, lightweight, and easy-to-source network cable solution.
With four balanced XLR inputs and mirrored XLR outputs, the Catapult TX4 acts as a signal launcher in the Catapult modular system—pair it with any Radial Catapult RX module for seamless, high-fidelity signal transmission across large stages or through existing cable infrastructure in installations.
