    CI-1RR - Overview

    Eliminates hum and buzz caused by ground loops

    The Jensen Iso-Max CI-1RR is a passive single channel audio ground isolator designed to eliminate hum and buzz caused by ground loops in the most demanding audio systems. The unbalanced stereo design begins with gold RCA connectors to ensure optimal signal transfer. The CI1RR is housed in a rugged steel enclosure that is fitted with screw-down flanges for easy installation in racks, under shelves or attached to cabinetry.

    The magic inside comes from a high performance Jensen Transformer that delivers pristine audio from 10 Hz to 40 kHz with less than 1dB of deviation, less than 0.05% harmonic distortion and less than 2° phase shift at all frequencies. The transformer is shielded in a MuMETAL® can to protect against external magnetic fields and prevent "spectral contamination" due to ultrasonic and RF interference. This assures your music will be faithfully delivered without distortion, coloration or artifact no matter what the program material or signal level.
