Radial Catapult MINI RX - 4 Channel XLR-M Snake
Revolutionize your cable management with Radial's surgical precision. The Radial Catapult Mini is a compact, passive audio snake system that transmits four channels of balanced analog audio over a single Cat 5 or Cat 6 Ethernet cable. Designed for the most demanding stage and studio environments, it eliminates the clutter of heavy multipair cables while ensuring absolute sonic transparency, without any digital conversion.

The Signal Authority: Why the Catapult Mini is Indispensable
In a world where rapid deployment and signal clarity are critical, the Radial Catapult Mini stands out as the ultimate tool. Whether you need to send mic or line signals through a building already wired with RJ45 or simplify your "drop snake" on stage, this box solves two major problems: bulk and interference.
Unlike complex digital systems, the Catapult Mini remains purely analog. The result? Zero latency, zero artifacts, and total reliability. Its 16-gauge steel chassis is virtually indestructible, true to Radial Engineering's reputation for robust construction.

History & Evolution
The idea of transmitting analog audio over network cable isn't new, but Radial has perfected it. The Catapult series evolved from the needs of touring technicians looking to utilize the existing network infrastructure (RJ45) found in stadiums and theaters. The "Mini" is a direct response to the demand for an ultra-compact, breakout-style format that can fit in an accessory case or behind a rack without sacrificing the brand's legendary durability.

[FAQ - SEMANTIC SEARCH]
Can Phantom Power (48V) be used in the Catapult Mini?
Yes. To use phantom power, you must use a shielded (STP) Cat 5 or Cat 6 cable. The shielding acts as a return path for the current. Using an unshielded (UTP) cable will prevent condenser microphones from working.
What is the maximum transmission distance without loss?
Radial tested the system over a distance of more than 100 meters (300 feet) without any signal degradation. Since the signal remains analog, the quality depends primarily on the quality of your Ethernet cable.
Does the Catapult Mini require an external power supply?
No. This is a 100% passive device. It contains no active circuitry requiring batteries or phantom power, thus eliminating any risk of simple electronic failure.
Can I plug the Catapult Mini into a network switch?
Absolutely not. The signal is purely analog. Going through a router or network switch would destroy the audio signal and could potentially damage your network equipment. The connection must be direct (point-to-point).
How to avoid ground loops?
Although the Mini is compact, it uses the Cat5 cable shielding for grounding. For complete isolation against hum and buzz, we recommend the Catapult versions with isolation transformers (TX4M/RX4L), available from Garage à Musique .
Is the Catapult Mini compatible with AES3 signals?
Although Cat5 cable can technically carry digital audio, the Mini is optimized for analog. For 110-ohm AES transmission over long distances, standard Catapult models are preferable.
Can you mix Microphone and Line signals?
Yes. Each channel is independent. You can send 2 mic signals and 2 line signals simultaneously without audible crosstalk thanks to the shielding of the twisted pairs.
Why choose Radial over a low-end solution?
The difference lies in RF rejection and mechanical robustness. A radial chassis won't creak under the weight of a flight case, and its internal welds are designed to withstand years of vibrations on the road.
Is the Cat7 cable compatible?
Yes, any cable with an RJ45 connector and 4 pairs of conductors will work. Shielded Cat6 or Cat7 will offer the best protection against electromagnetic interference.
