Dual VCA
A dual VCA module based on the LM13700 in the Eurorack format.
- Module size: 2HP (10mm)
- Power: 10mA (+12V); 10mA (-12V)
The control voltage (CV) of the VCA can be connected to the envelope from an ADSR. This VCA is designed to connect to the 555-based ADSRs (8V peak envelope voltage).
Project Source
The project files, including schematic and layout, are available on github
Features
The module is implemented with the LM13700 and features
- two independent DC-coupled VCAs
- audio input level control
- linear gain control with unity gain at 8V
