Radial Engineering Catapult TX4L 4-Channel Line-Level Transmitter – Cat5/6 Audio Snake Interface for Balanced Line Signal Distribution in Studio and Live Systems

The Radial Engineering Catapult TX4L 4-Channel Line-Level Transmitter is a professional Cat 5/6 audio snake interface designed for transmitting four channels of balanced line-level audio over long distances in live sound, studio, and broadcast environments.

As part of the Radial Catapult system, the TX4L converts standard line-level analog signals into a format that can be carried efficiently over a single shielded Cat 5, Cat 5e, or Cat 6 cable. This greatly reduces the need for bulky multicore analog snakes while maintaining clean, high-fidelity signal transmission across stage, studio, or installation setups.

At the receiving end, compatible Catapult receiver units convert the signals back into standard balanced line outputs, ensuring seamless integration with mixing consoles, recording interfaces, processors, and playback systems. This makes it a highly flexible solution for distributing multiple line-level signals across long distances with minimal noise and maximum efficiency.

The TX4L is specifically optimized for line-level signals, using precision balanced circuitry and transformer-based isolation design principles to preserve clarity, headroom, and tonal accuracy. It effectively minimizes interference, hum, and signal degradation even in electrically noisy environments.

Built for professional use, the unit features a rugged metal chassis and stage-ready construction, ensuring durability in touring, broadcast, and fixed installation applications.
