Palmer RIVER kyll Two-Channel Passive Line Isolation Box

Developed for use with consumer devices or professional synths, digital pianos, and small mixers, the Palmer RIVER kyll is a two-channel, line-isolation box designed to eliminate ground-loop hum and buzz when connected between two pieces of equipment. It can also be used to convert unbalanced signals into balanced signals for sending audio over long cable runs without interfering noise. The box can pass either a stereo signal or two independent mono signals without causing any sound alteration or noise.
