The Radial IceCube™ is a balanced line isolator that is used to eliminate hum and buzz caused by so-called ground loops and stray DC current. Normally placed at the input or receive end of an audio connection, the IceCubes’ high performance audio transformer inserts a galvanic bridge that disconnects the input from the output to block stray currents that cause noise in audio systems. The IceCube features an all-steel enclosure for extra durability as it protects against external electro-magnetic fields, ultra-though glass-filled nylon XLR connectors at each end and a set & forget ground lift switch. Inside, a custom made Eclipse transformer is flat from 20Hz to 30kHz and able to withstand signal levels to +15dB without choking. This makes the IceCube a terrific choice for music playback and voice for AV professionals, concert systems, and general purpose noise elimination in balanced audio.
