Noise plethora has three different noise generators:The first two are identical and are composed of digital algorithms followed by a 12dB analog multimode filter.Each program has two variables (Named X and Y) addressed by two manual controls and two associated control voltage INs.Ships with an extensive (and expanding) algorithms library: textures, wave clusters, harsh noises, and glitches. Generator C has three simultaneous outputs: White. Flat Response Classic white noise.Gritty. Granulous texture noise, with voltage-controlled grit quantity.Filtered. Is the White or Gritty noise followed by a 24dB multimode VCF. A total of 5 different noise sources in one module! Dimensions 14 HP 25 mm deep Current Draw 110 mA +12V 67 mA -12V 0 mA 5V
