Radial IceCube Passive Balanced Line-Level Isolator

Remove ground-loop hum from your audio system

The Radial IceCube is a passive, single-channel balanced line-level isolator with an Eclipse transformer. Insert it between two line-level devices to tackle hum and buzz caused by ground loops, with straightforward XLR input and output connections.

When a powered speaker starts humming during setup, connect the IceCube between the mixer and speaker to isolate the signal path. Its ground lift switch offers additional noise reduction, making it a useful problem-solving tool for live sound, AV installations and professional audio systems.
