Radial Engineering Catapult TX4 – 4-Channel Balanced Audio Snake / Audio Over CAT5 Extender – Excellent – Original Box – Free Shipping

I added catapults in several places of my home to enable me to connect with my studio but no longer use all of the rooms. Radial makes amazing products—built like a tank. This one looks new and has the original box.

Description

Up for sale is a Radial Engineering Catapult TX4 4-channel balanced audio snake in Excellent condition, complete with the original box and free shipping.

The Catapult TX4 is a clever and highly practical stage and installation tool designed to send four channels of analog or AES audio over standard Cat 5 or Cat 6 cable. Radial describes the Catapult platform as a passive audio snake, and the TX4 specifically provides four XLR-F inputs and four XLR-M thru outputs, making it useful for sending signals while also feeding a local monitor console or split. 

This is one of those pieces that solves real-world routing problems cleanly and efficiently. If you need a compact, reliable way to move balanced audio over lightweight network cable infrastructure without converting to digital, the Catapult system is a very smart solution. 

History of the Catapult TX4

Radial developed the Catapult series to provide a more practical alternative to bulky traditional analog snakes by using the widely available and lightweight Cat 5 / Cat 6 format. The TX4 and RX4 were designed to behave like a conventional four-channel analog snake while using standard shielded twisted-pair Ethernet cable, making them useful for live sound, installed systems, and remote recording setups. Radial’s documentation also notes support for analog and AES digital audio signals over the Catapult platform.
