The Fusion VCA module uses pentode tube 6Z1P and works as classical VCA with an option for great tube distortion when input level knob is cranked all the way. All Fusion modules are designed with visible tubes to provide that warm glow that all tube enthusiasts know well.
The Fusion VCA has two seperate CV inputs for amplitude modulation, one of which is attached to a dedicated attenuator. The Fusion VCA has an inverted output, 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 input is also low frequency), or something similar to contrary motion, as well as timbral effects by adding the two outputs together with changing volumes for cancellations and reinforcements to occur.
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.
