XFD

CV-Controlled Crossfader for Audio or Video

The XFD is a CV-controlled vactrol-based crossfader module, ideal for both audio and bipolar CV sources. It can be used as a cv-controlled attenuator: connecting just one input allows the signal to quickly fade in a VCA-like fashion.

Works with video synths! Selecting the video version and we will send high-speed op amps in place of TL072 ICs. (If you purchase the audio version, you can change it to video down the road by swapping the ICs and soldering in a few ceramic caps.)
