Radial Highline Passive Mono Line Isolator for Amp Modelers

The Radial Engineering Highline is a passive line isolator meticulously crafted to bridge the gap between guitar and amp modelers and professional audio mixers. Designed for both live performances and studio recording sessions, the Highline ensures that musicians can connect their equipment to PA systems without compromising on signal integrity or tonal quality. At its core lies a premium Jensen 1:1 transformer, renowned for delivering pristine audio performance while providing galvanic isolation to eliminate ground loop noise, resulting in a clean and noise-free signal.

One of the standout features of the Highline is its balanced output capability, which facilitates long cable runs to PA systems without any loss of signal strength or degradation in tone. This is particularly beneficial for guitarists and bassists who rely on amp modelers that often utilize 1/4" unbalanced connectors, which are susceptible to noise and signal loss over extended distances. By incorporating the Highline into their setup, musicians can maintain the full volume and clarity of their instrument's signal, ensuring that their performance is heard exactly as intended.

Moreover, the Highline offers versatility with its ability to accept stereo inputs and seamlessly sum them down to mono using the integrated Sum switch. This feature is invaluable in situations where PA channel availability is limited, allowing performers to maintain their stereo effects and presets without the need for extensive reconfiguration. Additionally, the Thru jack can serve as a second input, further enhancing the unit's flexibility in various performance scenarios.
