The Radial Highline Stereo is a two-channel passive line isolator designed to seamlessly connect guitar and amp modelers to a PA system or recording interface. Featuring premium Jensen transformers, it ensures exceptional audio performance by maintaining signal integrity, eliminating ground loop noise, and preventing unwanted interference from phantom power.

Modern amp and cab simulators offer a wide range of tones but often use unbalanced 1/4" outputs, making them susceptible to noise, signal degradation, and interference when connected directly to a mixer. The Highline Stereo solves these issues by converting unbalanced signals to balanced outputs, allowing for long cable runs without signal loss and consistent, high-quality sound at any venue or studio session.

Built for professional touring and recording, the Highline Stereo features a rugged steel chassis, premium connectors, and industry-leading isolation to deliver clean, noise-free performance every time. Whether on stage or in the studio, this line isolator provides full signal integrity with minimal phase shift, distortion, or coloration, ensuring your tone stays true.
