Cross-fades are accomplished by simultaneously increasing and decreasing the gain of two signals using complimentary VCAs. If only one signal input is used then it works more like a conventional VCA and fades between signal and silence. This module can be optimized for audio or CV cross- fading.
When built for audio the cross-fade point is only 3dB below unity. This reduces the perceived loss in level that would occur if both inputs are at half volume. If built for CV cross-fading the response is linear and cross over point is 6dB down. The benefit is an equal mix at center which is better for CVs but not for audio.
Being a dual module It is also possible to build one side for audio and the other for CVs. Please mention intended use when ordering so we can configure to suit.
