The IceCube is an ideal problem solver for today’s AV technicians and audio engineers, providing an easy way to insert an isolation transformer into the signal path to remove hum and buzz from ground loops, with a ground lift switch for additional noise reduction. Simply connect it between any two line-level devices, such as a mixer and a powered speaker, or a crossover and a power amp. The IceCube will eliminate ground loop noise without limiting the audio bandwidth or introducing phase shift, and it can handle hot signal levels without distortion.
Inside the IceCube, an Eclipse transformer isolates the input from the output, blocking out unwanted noise. While small transformers are rarely effective below 100 Hz, the IceCube is exceptionally linear between 20 Hz and 18 kHz. It is also capable of withstanding up to +10 dB at 20 Hz with less than 0.01% distortion. It represents a simple, effective solution to noise problems, without limiting bandwidth or introducing artifacts and other unpleasant sounds.
