The Korena take

Radial’s Highline Stereo is a dual-channel passive isolator for stereo line-level audio. Jensen transformers provide the isolation needed to address hum, buzz, and ground-loop issues while retaining signal clarity and dynamics. Because it needs no external power and accepts balanced or unbalanced signals, it can be placed between stereo playback devices, keyboards, or mixing consoles without adding a power requirement. It suits studio routing, live-sound systems, and broadcast signal paths.
