Radial Engineering ICE Cube - Passive Line Isolator

 The IceCube stands as an optimal solution for contemporary AV technicians and audio engineers, offering a simple means to integrate an isolation transformer into the signal path. This effectively eliminates hum and buzz caused by ground loops, with an added ground lift switch for supplementary noise reduction. Connecting the IceCube between any two line-level devices, such as a mixer and a powered speaker or a crossover and a power amp, effortlessly removes ground loop noise.

Notably, the IceCube achieves this without compromising audio bandwidth or introducing phase shift. It excels at handling hot signal levels without distortion, ensuring a clean and unaltered audio experience.
