Erica Fusion Ring modulator module uses pentode tube 6Z1P and it multiplies two signals to create unique waveforms rich in partials, bell like sounds, as well as tube distortion effects. If the Modulation signal goes into low frequency range, or an envelope is patched in, the Fusion Ring modulator can double as a VCA, accepting unipolar positive, unipolar negative and bipolar signals. The Fusion Ring modulator also 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 both the modulation wave and carrier wave 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. All Fusion modules are designed with visible tubes to provide that warm glow that all tube enthusiasts know 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.
- Inputs for both the carrier wave and the modulation wave.
- Independent attenuators for each levels control.
- Doubles as a Tube VCA
- Two outputs, one inverted.
