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 Engineering Highline Stereo is ideal for players who utilize amp simulators on their pedalboard. It 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 balanced outputs that can be run over long distances without signal degradation.Stereo Passive Line Isolat
