Overview

The Radial Engineering LX3 is a 3-channel passive line splitter built for professional audio environments where clean, isolated signal distribution is critical. At its core are Jensen transformers — widely considered the gold standard for audio isolation — which allow you to send a single mic or line-level signal to three separate destinations without introducing ground loops, hum, or signal degradation. The balanced XLR and TRS input accommodates a variety of source connections, while the built-in input pad lets you tame hot signals before they reach downstream gear.

Because the LX3 is entirely passive, it requires no power supply, making it a dependable and low-maintenance solution for live sound, broadcast, and studio applications. Whether you need to feed front-of-house, monitors, and a recording rig simultaneously, or distribute a signal across multiple processing chains, the LX3 handles the task with the transparency and reliability that Radial Engineering is known for. Its compact, rugged enclosure is designed to withstand the demands of touring and daily professional use.

Pros & Cons

👍 Pros

  • Jensen transformers deliver excellent signal integrity and galvanic isolation between outputs.
  • Passive design means no power supply needed and no added noise or distortion.
  • Three isolated outputs allow routing to multiple destinations without ground loop issues.
  • Accepts both XLR and TRS inputs for flexible integration into different signal chains.
  • Built-in input pad handles hot signals without clipping.

👎 Cons

  • Passive design introduces slight insertion loss compared to active splitters.
  • Only three output channels, which may not be enough for larger routing requirements.
  • No ground lift switches on individual outputs for per-channel ground loop troubleshooting.
  • Premium Jensen transformers contribute to a higher price point than basic passive splitters.

Frequently Asked Questions

It is a fully passive device, meaning it requires no external power supply and introduces no active electronics into the signal path.
It uses Jensen transformers, which are industry-standard components known for exceptional audio fidelity and isolation.
Yes, the input accepts both balanced XLR and TRS connections, giving you flexibility in how you feed signal into the unit.
The input pad attenuates the incoming signal level, which is useful when working with hot line-level sources to prevent overloading downstream equipment.
