Cat 5 Analog Snake

4-Channel Cat 5 Audio Snake

The Catapult is a passive audio snake that allows you to send four channels of analog audio over standard Cat 5 or Cat 6 Ethernet cable.

  • Send four channels of analog audio over a single Cat 5/6 cable
  • Works with a building’s existing cable infrastructure
  • Choice of direct-wired or transformer isolated splits
  • Economical Cat 5/6 cable replaces bulky multi-channel audio snakes

Analog audio over Cat 5 wiring

The Catapult TX4 and RX4 act like a typical four-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 a shielded Cat 5 cable between any two Catapult modules and they will use the analog conductors in the cable to deliver four balanced audio lines to any destination.

Straight-wire passive operation

Catapult 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 the XLRs to the RJ45 connector on a Cat 5 cable ensures that your audio passes through without coloration or distortion.

Utilize pre-existing cable installations

As many buildings are already pre-wired for Cat 5, you can take advantage of this to transmit audio between distant rooms without the need to install or supply new cabling. This eliminates the need for bulky and expensive multi-channel audio cable, and allows contractors to benefit from installed network cable and easily connect from one room to another.

Mix & Match to add transformer isolation

Any pair of Transmit and Receive units across the full Catapult range will be compatible with one another. The standard Catapult also includes some additional model variations, for creating a custom snake designed for your unique application. If you need transformer isolation to prevent hum and buzz when splitting audio signals, the TX4L and RX4L have line level isolation transformers for splitting playback tracks or outputs to amp racks. Meanwhile the TX4M and RX4M can be employed when splitting mic signals on stage.

Catapult Applications

Using the Catapult as a return snake

The Catapult is the perfect return snake for corporate events where you need to run a couple of lines back to the stage and monitors. Use the RX4L line isolation module to eliminate ground loops.

Using the Catapult as a 4-channel mic splitter

Use the Catapult TX4M to split the mics between the monitor desk and front of house with Eclipse transformer isolation to deliver a noise-free signal, saving hours of tedious trouble shooting.

Using the Catapult as a sub snake on stage

Cleaning up the stage while lowering the set-up times have become essential components in production. Use the Catapult at the front of the stage or next to the amps to create zones for quick deployment.

Using the Catapult as a line isolator

The Catapult RX4L is the perfect 4-channel line isolator. Simply connect it in line with any line audio device to eliminate hum and buzz caused by ground loops.

Using the Catapult to network audio

Use the pre-existing Cat 5 or Cat 6 wiring in the building to network audio from one room through the walls to another. The XLR connections at each end make it easy!

Run four AES signals across Cat 5 cable platform

110 Ohm AES signals can easily travel across Cat 5 and Cat 6 Ethernet cable. Connect to the four Catapult TX4 XLRs for eight channels of audio for remote recording.


All Radial Catapult modules are compatible with each other and sold individually, so you can select whichever combination best suits your needs. The Catapult Mini RX and TX can be used together as a pair, creating a compact 4-channel audio snake. However, if you prefer to have a stage box to plug microphones into, but want a compact breakout cable that fits in the case with the mixer, combine the Catapult TX4 with the Catapult Mini RX. With the addition of the Catapult Rack units, you can also incorporate equipment racks into your setups for greater flexibility, with each rack unit essentially functioning as three 4-channel modules in a 1RU rackspace. With a wide variety of modules available, you can customize your stage or recording studio setup to suit any application.
