Radial Engineering Highline Stereo 2-Channel Passive Line Isolator

Presenting the new Radial Engineering Highline Stereo 2-Channel Passive Line Isolator.

The Highline Stereo is a full-featured 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 premium Jensen 1:1 transformers, which retain 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 outputs of the Highline Stereo allow for long cable runs to the PA, and the device also blocks phantom power so it never reaches the pedalboard. The Highline Stereo can be easily reconfigured for multiple setups with the use of two summing switches: these allow you to connect to the PA or your stage monitors in either stereo or mono.

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 Stereo addresses these issues by inserting 1:1 Jensen transformers into the signal path, which provide isolation to reduce noise, protect against phantom power, and ensure that the audio signals remain at line level for direct connection to the PA system.
