IceCube™ IC-1 Specifications

The Radial IceCube IC-1 is a compact line-level isolator designed to reduce hum and buzz caused by ground loops and stray DC voltage. The true marvel with this design is the diminutive size yet amazing response, particularly in the low end where smaller transformers tend to fail. The IceCube has been optimized to work in the commonly used -30dB and +15dB range with both balanced and unbalanced devices. This makes the IceCube a great problem solver for a wide array of applications where retaining the full audio spectrum is required.
