Module A-126-2 is a fully analog frequency shifter for audio signals. A frequency shifter is an audio processing unit that shifts each frequency of the incoming audio signal by the same frequency.
An envelope follower is used to derive an envelope signal from the audio signal.
The up and down outputs are internally connected to the inputs of a voltage controlled crossfader.
The module is fully DC coupled so that even very low frequency shifts are possible (with external quadrature VCO)
The module is complete built in thru-hole technique (including the dome filter), no smt.
Because of the 100% analog circuitry the module requires a few minutes heat-up time until all parameters are stable
