Voltage Controlled Crossfader / Triangle to Sine Waveshaper
The A-184.2 is a precise Triangle to Sine converter, which converts a triangle waveshape into a near perfect pure sinewave. Typical uses would be the achieve a better sine wave form VCO’s such as the A-110.1 etc, or LFO’s that don’t have a sine wave.
The second half of the A-184.2 is the voltage controlled crossfader, which uses two high quality (SSM2614) VCA’s which operate down to DC.
The triangle input and the sinewave generated waveshape is passed to the crossfader, and so a voltage controlled crossfade between triangle and sine is achieved
