Radial Highline Stereo Passive Line Isolator for Amp Modelers

The Radial Engineering Highline Stereo is a two-channel passive line isolator meticulously designed to connect guitar and amp modelers directly to mixers for both live performances and studio recordings. By incorporating premium Jensen 1:1 transformers, the Highline Stereo ensures that your signal maintains its full integrity, delivering pristine audio without any added noise or distortion. This design not only preserves the original tone but also provides galvanic isolation, effectively eliminating ground loop hums and safeguarding your equipment from potential issues like phantom power.

One of the standout features of the Highline Stereo is its balanced XLR outputs, which facilitate long cable runs to PA systems without any loss of signal strength or tonal degradation. This is particularly beneficial for musicians who utilize amp simulators with unbalanced 1/4" outputs, as these are prone to noise and signal loss over extended distances. The Highline Stereo addresses this challenge by converting unbalanced signals to balanced outputs, ensuring a clean and robust signal reaches the mixer, regardless of the venue size.

Versatility is at the core of the Highline Stereo's design. It boasts two summing switches that allow for seamless reconfiguration between stereo and mono outputs, catering to various performance setups. The XLR Sum switch enables the left and right input channels to be merged into a mono signal at both XLR outputs, ideal when the mixer has limited available channels. Simultaneously, the Thru Sum switch combines the input channels into a mono signal at the Thru outputs, allowing musicians to monitor their performance through a single stage amplifier while still sending a stereo signal to the PA system. This flexibility ensures that the Highline Stereo adapts effortlessly to the dynamic needs of modern musicians.
