Description

The Erica Synths Fusion VCF v2 is their take on a four pole lowpass filter. But with valves!

Each side of the double triode drives signal between 2nd and 3rd stage of the filter, while germanium diodes are used to limit the output signal. The Fusion series modules are designed by combining vacuum tubes and semiconductors – therefore they bring the warm, powerful sound and overdrive possibilities of vacuum tubes into your modular system.

With this module you’ll get an ultimately deep sounding VCF with a unique character. Ingenious resonance volume compensation circuit and filter slope selection makes it ideal for live performances. Bonus feature – 3 input mixer with dedicated mixer output. Try patching the MIX OUT into one of the mixer inputs, increase the input level until the mixer goes into self-oscillation and use the filter to alter the drone, you have! The Fusion VCF is an instrument on it’s own!

 Features:

  • 4 pole lowpass resonant VCF with tube drive between stages
  • Three input signal mixer
  • Selectable 24db/12dB filter slope
  • Signal drop compensation, when resonance is increased
  • Germanium diode based output signal limiter

A note about power:

Please make sure your PSU has some power headroom before installing Fusion modules – especially multiple units. (ie: you’ll need enough power for the Fusion modules to be able to potentially use DOUBLE their required power during the startup process)

All Fusion modules by default are configured to work with a regular Eurorack PSU. However, due to the fact that cold tube heaters have lower resistance, Fusion modules have significant power consumption peak at startup, when power consumption almost doubles for 1-2 seconds.

This is not a problem with linear PSUs that have power inertia, but you may find that the internal protection feature on switching PSUs temporarily turns off the power supply if there isn’t enough headroom to accommodate this additional power consumption.

The FUSION VCF v2 is slightly different, in that it doesn’t require quite as much extra power at startup, but what it DOES need it draws from the negative rail – see below:

Width: 14hp
Depth: 35mm
Power: 35mA @ +12V / 170mA @ -12V (NOTE: for a few seconds at start-up, power consumption is actually 250mA on the -12v rail)
