Independent shopping perspective
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.
Strong match
Who this is for
- Isolating a stereo playback device before it feeds a mixer or other audio system.
- Cleaning stereo keyboard connections in live sound or recording-system routing.
- Broadcast, studio, or live setups where hum and ground loops affect stereo line-level signals.
