Radial Highline Stereo Passive Line Isolator

The Highline is a passive line isolator designed to connect guitar and amp modelers to a mixer for live touring and recording applications, featuring a premium Jensen transformer for exceptional audio performance.

Amp simulators are more popular than ever, but they present a unique set of problems for guitar and bass players who want to interface them with a PA system. While amp sims can produce line-level outputs, they often have ¼" unbalanced connectors that aren't designed for long cable runs, and they encounter hum and buzz from ground loops when connected directly to the PA. The Radial Highline is ideal for players who utilize amp simulators on their pedalboard. The
Highline features premium Jensen 1:1 transformers that retain the full volume from the amp sim while providing isolation that breaks up ground loops and protects against phantom power, along with a balanced output that can be run over long distances without signal degradation.

Elevate your tone
The Highline is a line isolator that is specifically designed to address the needs of instrumentalists who use amp modelers, allowing them to seamlessly connect to a PA or a recording system while maintaining their full signal integrity with no added noise or distortion. The Highline features a premium Jensen 1:1 transformer, which retains the full volume level from the pedalboard to the PA, while also providing galvanic isolation that eliminates ground loop noise for a clean and noise-free signal. The balanced output of the Highline allows for long cable runs to the PA, and it also blocks phantom power so it never reaches the pedalboard. The Highline can also accept stereo inputs and sum them down to mono with the use of the Sum switch.

Designed for amp modelers
Guitarists and bassists who use utilize amp modelers on their pedalboard have a unique set of problems: While amp sims can produce line-level outputs, they often still use 1/4" unbalanced connectors that won't support long cable runs without degrading the tone of the instrument, and they are particularly susceptible to noise from ground loops when connected directly to the PA. The Highline addresses these issues by inserting a 1:1 transformer into the signal path, which provides isolation to reduce noise, protects against phantom power, and keeps the signal at line level for direct connection to the PA system.
