Radial HighLine Passive Line Isolator
The Radial HighLine is a passive line isolator engineered to connect guitar and amp-modeler outputs to mixers or PA systems without adding noise, distortion, or tone coloration. Its precision-wound Jensen JT-11-YMPC transformer provides galvanic isolation—blocking phantom power and eliminating ground-loop hum—while preserving a flat frequency response from 20 Hz to 20 kHz.
Designed for both studio and touring use, the HighLine features an input Sum switch to combine stereo sources into mono and a Thru Sum option for local monitoring. Housed in a rugged 14-gauge steel outer shell with a 16-gauge chassis and powder-coat finish, it delivers reliable performance night after night.
