The Catapult Mini TX from Radial Engineering acts as a 4-channel audio snake. It allows 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. The Catapult Mini TX features four female XLR inputs on cable tails and an RJ45 output, which sends analog audio over cat 5/6 Ethernet cables. The housing is made of 16-gauge steel for handling any environment and is powder coated.
