The Doepfer A-184-2 VC Crossfader/Triangle-to-Sine Waveshaper is a VC crossfader/triangle-to-sine waveshaper module, with a width of 4HP, and designed as an expansion module for LFOs/VCOs. The A-184-2 module is the combination of two functions and planned primarily as an expansion module for VCOs or LFOs, including the models A-110-1, A-110-2, A-145, and A-147-2. The upper section is a very precise triangle-to-sine converter. It can be used to convert any triangle waveform into a virtually perfect sine.
The converter is better than the simple diode converter used in previous Doepfer modules. Two trimming potentiometers are used to optimise the sine shape. The converter should be assigned to one VCO or LFO because the trimming potentiometers have to be re-adjusted if the input level or DC offset of the input signal changes. If the trimming potentiometers are deliberately mis-adjusted it can be used also as a waveshaper for non-sine waveforms.
The lower section is a voltage controlled crossfader. It has two inputs; A and B. The two signals are mixed together with variable percentage. When the manual control CF is fully CCW, only signal A appears at the CF Out socket. When the manual control CF is fully CW, only signal B appears at the CF Out socket. In the center position of the manual control both signals appear with the same level. In addition a control voltage input CV with an attenuator is available to enable voltage control of the crossfade. The crossfader uses two high quality VCAs (SSM2164), while the inputs and outputs are DC coupled.
