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 10 x 4 cm, the compact design begins with two super-duty glass-filled nylon XLR's 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 100 Hz, the IceCube is exceptionally linear from 20 Hz to 18 kHz. It is also able to withstand up to +10 dB at 20 Hz 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 artefacts.

These features combine to make the IceCube an ideal problem solver for the AV technician and audio engineer that work in the fast-paced world of live touring, AV rentals and system integration.
