Radial LX3

Essential Information About the Radial LX3 Signal Splitter

• 1 input to 3 outputs to simultaneously distribute the same signal to multiple destinations (recorders, consoles, monitoring systems, effects).


• Two transformer-isolated outputs with Jensen JT-123-FLPCH transformers to limit ground loops and preserve signal integrity.


• Combo XLR / 6.35mm Jack input compatible with both balanced and unbalanced wiring, ideal for studio and broadcast use.


• Robust metal chassis and non-slip pad for reliable daily use in the most demanding setups.

A splitter designed for the demands of studio and broadcast environments

In a professional environment, you are often asked to do "more" with a single signal: powering both a recorder and a console, providing a clean feed for a monitoring system, or sending a microphone to multiple processing chains. The Radial LX3 was specially developed for this type of workflow: it allows you to split one incoming signal into three paths with a clear architecture focused on reliability and component quality consistent with Radial's reputation in studios and among service providers.

Within the Radial range, the LX3 positions itself as a simple, robust, and highly professional distribution tool: no unnecessary features, but well-chosen technical solutions to secure your connections and routings, notably thanks to transformer isolation on two outputs.

Who is the Radial LX3 for and when to use it?

The LX3 is aimed at sound engineers, broadcast technicians, recording studios, post-production control rooms, service providers, and equipped venues that need to duplicate a signal cleanly without resorting to makeshift solutions. It is also a very practical solution when you want to send a microphone through multiple units (for example, several processors or effects) while maintaining consistent and controlled distribution.

Practically speaking, the LX3 is relevant whenever you need a reliable split: sending the same signal to multiple recorders, powering different monitoring systems, or providing a dedicated output to another control room. The goal is not just to "duplicate" but to do so while reducing the risks of electromagnetic interference and ground issues, which are particularly common in multi-device configurations.
