Radial IceCube IC-1 Balanced XLR Line Isolator

The Radial IceCube™ IC-1 is a balanced line level isolator designed to quickly eliminate hum and buzz problems in an audio system by simply inserting it into the signal path.

Measuring just over 4" x 1 ½" (10 x 4cm), the compact design begins with two super-duty glass-filled nylon XLRs at each end with heavy duty nickel-silver contacts that will not tarnish over time. Unlike other isolators that are made of plastic, the IceCube is made from solid 16 gauge steel and finished in a tough powder coat. The steel outer shell is not only more durable, it provides excellent shielding against electromagnetic fields radiated by power cables, dimmers, motors and power supplies - delivering consistently quieter results when deployed. This is augmented with a 'set & forget' ground lift switch to eliminate hum and buzz caused by ground loops.

Inside the IceCube, a proprietary Eclipse transformer isolates the input from the output and blocks stray DC currents. While small transformers rarely perform well below 100Hz, the IceCube is exceptionally linear from 20Hz to 18kHz. It is also able to withstand up to +10dB at 20Hz with less than 0.01% distortion. It is a quick and easy problem solver that will eliminate noise without limiting the bandwidth or introducing phase shift, harsh sound or unpleasant artifacts.
