Radial Engineering Highline

Retain the Full Output from your Pedalboard or Amp Simulator

No loss of signal strength or tone when connecting to a mixer.

Radial's renowned reliability and build quality.

Precision-wound Jensen Transformer delivers exceptional clarity and warmth.

Passive, plug-and-play design requires no external power.

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
