Radial Catapult Rack RX/TX Cat 5 Analog Audio Snake now shipping!

Radial Engineering's new Catapult Rack TX and Catapult Rack RX are now available! The Catapult Rack TX and RX expand Radial’s line of audio over Cat 5 cable units, providing a streamlined and efficient way to handle analog audio distribution across significant distances.

The Catapult Rack TX and RX transform three standard Cat 5 or Cat 6 Ethernet cables into a passive 12-channel audio snake. This eliminates bulky, expensive traditional snakes while maintaining pristine sound quality. Perfect for both stage and studio, the Catapult TX and RX single rackspace units allow effortless transmission of mic and line-level signals with zero signal loss, interference, or digital conversion required. The versatile design enables seamless integration with other Radial audio over Cat 5/6 modules for maximum configuration flexibility.

Built with Radial's signature ruggedness, the Catapult TX and RX boast durable steel enclosures, Neutrik etherCON connectors for secure cable locking, and reversible rack ears for easy placement in any setup. The ground lift function on each bank of XLRs minimizes unwanted noise, ensuring optimal signal clarity even over long runs.

Rackmount Cat 5 Analog Audio Distribution

Send your analogue audio signal over CAT 5

The Radial Catapult Rack solution is a passive audio snake that allows you to send or receive 12 channels of analog audio over standard Cat 5 or Cat 6 Ethernet cables.

Key Features

  • Distribute 12 channels of balanced audio over three Cat 5 cable lines
  • Easily combines with any other Radial Catapult modules
  • Robust steel enclosure and locking Neutrik etherCON connectors
  • Reversible rack ears for optimal configuration with any setup


Analog audio over Cat 5 wiring

The Catapult Rack TX and RX act like a typical multi-channel analog audio snake; they allow you to send mic or line-level signals from one location to another without signal loss, noise, or interference, and without any digital audio conversion needed. What makes the Catapult system unique is that it utilizes Cat 5 Ethernet cable, which is widely available, lightweight, and economical. Simply connect one shielded Cat 5 cable for every four channels of audio and deliver it to any other Radial Catapult module – it will utilize the analog conductors in the cable to deliver four balanced audio lines to any destination.

1 Rackspace, 3 times the channel count

The Catapult Rack units operate like three modules in one chassis. Since each Cat 5 Ethernet cable can carry four channels, the 12 XLRs on each Catapult Rack are split into three banks, each with their own noise-eliminating ground lift switch and RJ45 Ethernet jacks on the rear panel. You can use three Ethernet cables to connect all 12 channels to a single location, or split them off to any of the Radial Catapult stage boxes, providing you with a fully customizable audio snake system that can connect multiple destinations at once and even include transformer isolation where needed.

Rugged and flexible

The Catapult Rack TX and RX are built to handle the toughest pro touring environments, and like all Catapult modules they include Neutrik etherCON RJ45 connectors. These allow you to use compatible cables with a protective metal shell around the Ethernet connector that protects against accidental disconnection while also preventing damage to the RJ45 plug itself. Another useful feature on the Catapult Rack is the addition of reversible rack ears, which can be mounted on either side of the chassis, so you can have the XLRS or the Ethernet connections facing outwards as necessary

Straight-wire passive operation


Catapult Rack modules require no power to operate, and since they keep the signal in the analog realm, no digital conversion is necessary. Straight-wire connection from each bank of XLRs to the RJ45 connector on a Cat 5 cable ensures that your audio passes through without coloration or distortion.
