The Radial LX-3 is a high-performance balanced line-level splitter designed to send one audio signal to as many as three destinations at once. Completely passive with no need for power, you simply plug in and the LX-3 goes to work delivering your audio wherever it needs to go.

The heart of the LX-3 is a premium Jensen® JT-123-FLPCH transformer. This has the industry's best combination of frequency response, signal level handling, and low distortion, providing the highest possible signal quality. It features two isolated outputs to eliminate hum and buzz from ground loops, along with a third direct output. All three XLR outputs have ground lift switches for additional noise suppression, and a switchable -12dB input pad allows you to connect even the hottest line outputs without fear of overloading or distortion. The input of the LX-3 is accessed with an XLR/TRS combo jack, which allows you to connect via balanced or unbalanced cables; the LX-3 will automatically balance the signal at the isolated outputs, preventing interference and signal degradation over long cable runs.

Like all Radial products, the LX-3 is built rugged to handle years of abuse on the road, with heavy-duty 14-gauge steel construction. A book-end design creates a protective housing around the connectors and switches to prevent damage even in a harsh concert touring environment, and an internal I-beam frame makes it almost impossible to torque the circuit board and damage connections. The LX-3 can be mounted in a Radial J-Rak™, allowing up to 8 units to be rack-mounted together or combined with other compatible Radial DI boxes for a for a streamlined and mess-free setup. Typical applications include splitting a signal in the studio to send to multiple effects, feeding a console output to a number of recording devices, or even splitting a signal on a live stage to multiple monitors or headphone mixers.

The Radial LX-3 delivers pristine audio and ultra-quiet performance that allows you to confidently and professionally split your signal to any destination.
