The Noise Engineering Kith Ruina (Black) is a 4HP Distortion Module for Eurorack Synthesizers with a 3-Band Equalizer. The Equalizer is adjustable in the High and Low Frequencies as well as in the mids between 200Hz and 800Hz. The Pre-Wired Signal Path feeds the incoming Audio Signal first through the Distortion and then through the EQ. The Signal Path can be reversed using a Patch Cable or you can simply use the 2x Units in parallel.
