Radial IC-1 Ice Cube Line Isolator

• Transformer equipped line isolator.

The Ice Cube is most commonly used in between a mixer and powered monitor. It breaks the ground loop on these devices via use of its custom transformer. It's incredibly easy to use - just set it and forget it. If any hum still persists then it's likely a ground loop wasn't the problem.
