Ring+VCA

  

The Circuit Slices Ring+VCA (CS045) is a dual-function module for Eurorack-compatible synthesizers. Packed in a narrow panel is both a quality classic analog ring modulator circuit and a basic linear VCA. Ring modulators typically are patched to a VCA – this ring modulator includes the VCA.


Features and Specifications for the CS045 Ring+VCA

The “Ring Modulator” or “Balanced Modulator” or “4-Quadrant Multiplier”, circuit uses a quality Analog Devices AD633 chip

· Low feedthrough (+/-0.1% Yin and +/- 0.3% Xin typical)

· Low noise (90 µV rms) 

· No ‘Nulling’ adjustments are required

· See Analog Devices AD633 data sheet for complete chip specifications

The VCA, or “two-quadrant multiplier” circuit uses a transconductance chip

The VCA is trimmer-adjusted for unity-gain output with a 5V CV input (user adjustable trimmer)

The ring modulator output is “normal” patched to the VCA input

The VCA and Ring Modulator can be used separately – patching to VCA IN disconnects Ring OUT

Includes power cable and case screws
