Independent shopping perspective
The Korena take
IceCube IC-1 is a compact balanced line-level isolator for tracking down hum and buzz by placing it in the signal path. Its ground-lift switch addresses noise caused by ground loops, while the internal Eclipse transformer isolates input from output and blocks stray DC currents. The steel enclosure adds shielding from electromagnetic fields produced by power cables, dimmers, motors, and power supplies. It stays linear from 20 Hz to 18 kHz and is built for fast-moving live, AV-rental, and system-integration work.
Strong match
Who this is for
- Live touring systems where hum or buzz needs a quick signal-path solution.
- AV rental and system-integration jobs affected by ground loops or electromagnetic interference.
- Audio-engineering work requiring balanced line-level isolation without limiting stated bandwidth.
