Radial Catapult Mini TRS

The Catapult Mini TRS is a passive, four-channel Cat5 interface module that converts balanced quarter-inch TRS connections onto a single RJ45 run. Its job is simple and specific: you have a rack full of interface outputs or playback device sends on TRS jacks, and you need to move those signals across the stage without running four individual cables. One Cat5 does it. On the far end, a paired Catapult receiver — a Mini RX or RX4 — breaks the signal back out to XLR for drive racks, splitters, or wireless systems. No power, no transformers, no latency.

Four bidirectional TRS jacks and one RJ45 is the entire port count, which tells you exactly what this thing is and is not. Passive means signal integrity lives or dies on cable quality and run length — Cat5e or Cat6 in good condition over stage-reasonable distances behaves well, but this is not a digital system and it is not immune to noise pickup on a long or poorly shielded run. At one kilogram and zero rack units, the Mini TRS is meant to live on the back of a rack shelf, zip-tied to a rail, or mounted in Radial's own Catapult rack frame rather than eating a rack space of its own. Power draw is zero, which matters when you're budgeting a conditioner.

If your playback rig or IEM rack uses an interface with TRS line outputs — an RME, MOTU, or similar — and you need those signals to travel any real distance to stage, this is a clean, affordable answer. The interchangeability across the Catapult system is genuinely useful: you can mix TRS and XLR modules at each end depending on what the destination gear requires. Skip it if your interface already has XLR outputs, since a standard Catapult XLR module covers that without any adapter chaining. Also skip it if your run is very long or in a high-RF environment — a digital snake will serve you better there.
