VCA – AC coupled

CHF 89.00 excl. VAT

The VCAs circuit design is based on an advanced version of the famous “blackmer gain cell” by the THAT Corporation.
This is the AC coupled version of the VCA. A large coupling capacitor allows low frequencies to pass trough the circuit but pure DC offsets will be cut.

The module features a potentiometer for manual gain control. A second potentiometer to adjust the amount of CV1. CV2 is a direct control voltage input for gain control which is not attenuated.

The circuit is set to -110dB Gain with gain potentiometer set to zero and no external CV applied.
Sensitivity of the CV inputs is set to 95mV/dB.

The circuit processes voltages up to 20Vpp without clipping! Voltages over 20Vpp get hard clipped.
