The PLASMA Rack distorts audio signal by transforming it into visible high voltage electric discharge in a xenon tube. The wide frequency spectrum works great with various sound sources. The PLASMA rack has a unique gritty distortion and carefully designed controls. The naturally occurring noise gate effect interacts with the VOLTAGE knob and input level. This combined with the DRY/WET mix knob makes PLASMA Drive perfect for drum machines and fx tracks.
Modulating the xenon lamp creates extraordinary TREMOLO and RING MOD sounds. The CLEAN GATE effect adds the signature PLASMA gating effect to the clean signal. The SUSTAINER circuit allows to dial in sputtery broken sounds without losing sustain. The OVERSATURE circuit overloads the tube and adds upper harmonics and changes the dynamic response. This together with sophisticated I/O and full MIDI implementation makes for a powerful post-production and post-destruction machine.
- Distortion that integrates in a studio with instrument/line level signal processing and balanced & unbalanced I/O;
- Previously unheard gritty CLEAN GATE effect that can be applied on dry sound without distortion;
- Dynamic TREMOLO / RING MODULATOR effect modulates the xenon lamp resulting in a unique effect that can be controlled by the input level;
- Distort stereo tracks with two units in master/slave configuration;
- Recall your distortion presets with MIDI PC and control all parameters with MIDI CC.
