Highline

The Highline sits between an amp modeler or other line-level pedalboard source and a mixer. A Jensen 1:1 transformer in the signal path keeps the signal at line level, so volume and tone are retained, while providing galvanic isolation that removes ground-loop noise. The output is balanced, which allows long cable runs to the PA, and the transformer blocks phantom power so it does not reach the pedalboard.

A Sum switch lets the unit accept a stereo source and fold both channels into the single XLR output. With Sum engaged, the Thru jack works as a second input, so presets do not need to be changed when channel count at the PA is limited. With a mono source, the Thru can instead feed a stage amplifier for local monitoring while the XLR output goes to the PA.

The unit is sized for pedalboards. Radial TrainTrack brackets are listed as an accessory for mounting P-Class devices under a pedalboard. A stereo version, the Highline Stereo, is available as a related product.
