From Radial Engineering

The Radial Highline is a premium line isolator designed specifically for amp simulators and pedalboards. Featuring a Jensen transformer, the Highline retains the full output of your gear while delivering clean, balanced signals free from hum and interference. With Radial’s renowned build quality, the Highline is built for long-term reliability on stage or in the studio. A 1⁄4” Thru jack provides flexible connectivity for stage amps or stereo sources, and the sum function allows effortless mono blending for streamlined setups.
