Fusion VCO Mixer - 17HP


Erica Fusion dual VCO Mixer module is designed to mix several waveforms from your VCOs in order to get interesting and unique waveshapes. It also can be used as a timbral waveshaper, if you apply PW modulated pulse signal to one of the inputs – it will radically change resulting waveform in real time. A special feature of this mixer provides great tube distortion effects with level knobs cranked all way clockwise. Of course, you are not limited to mixing only VCO signals – the module works with any audio signals. The VCO mixer has an inverted output for each mixer, giving a signal that's 180 degrees out of phase from the main output. This feature can be used for a variety of effects, including stereo panning CV (if the audio signals being mixed are low frequency), or something similar to contrary motion, as well as timbral effects by adding the two waves together at various volumes for cancellations and reinforcements to occur. Since the module features two mixers, you can use it even for stereo applications! Visible tubes also provide that warm glow that all tube enthusiasts know too well. 

Erica Fusion modules have insignificant (max 15mA) power consumption from eurorack power supply unit (PSU), but they require separate, easy to install 6VAC PSU for tube heaters, also available from Perfect Circuit Audio.
