Radial Engineering Lx-3 Passive 3 Channel Line Splitter
Best professional solution for clean, noise-free audio signal distribution.
The Radial LX-3 is a passive, balanced line-level splitter designed to distribute a single audio signal to multiple destinations without external power. It features premium Jensen transformers for exceptional audio fidelity, ensuring broad frequency response and minimal distortion. To combat noise, it offers two electrically isolated outputs per channel, preventing ground loop hum, plus a third direct output. All outputs are equipped with ground lift switches, and a switchable -12dB pad protects against signal overload. Its robust 14-gauge steel construction makes it ideal for demanding live sound or studio routing applications.

Know before you buy
No, the LX-3 features a completely passive design. It does not require batteries or external power, making it reliable for live setups where power outlets are limited.
The unit includes two transformer-isolated outputs per channel, which electrically decouple the signal path from the destination equipment. Additionally, each XLR output features a dedicated ground lift switch to further eliminate noise caused by ground loops.
Yes, each channel provides one direct output and two isolated outputs, allowing you to send a single line-level signal to three different devices simultaneously.
The -12dB pad is designed to prevent signal distortion when dealing with high-output sources. Engaging it reduces the input level, ensuring your signal remains clean and free of clipping.
Absolutely. It is built with a 14-gauge steel chassis, which provides the durability needed to withstand the rigors of constant transport and demanding live sound environments.
The premium Jensen transformers are specifically chosen for their sonic transparency and flat frequency response. They ensure your audio remains accurate and free of coloration or distortion across the full 20 Hz to 20 kHz range.
