CubuSynth - Dual Vintage VCA

• size: 8hp

• single Thru-Hole PCB design

• 10 pin eurorack power connection

The CubuSynth Dual Vintage VCA is a nice sounding, zero bleed, analog Voltage controlled amplifier based on the LM13700 Dual OTA. It can work as two independent VCAs or as a stereo unit, and CV input 1 on channel 1 is normalized to the CV input 1 on channel 2. (same signal can control both Channels) The Original concept is designed by Tom Wiltshire aka "Electric Druid".

1 LEVEL Sets the Amplitude for each channel.

2 CV AMOUNT Attenuates the Control voltage from CV input (3)

3 CV CV input for the amplitude Modulation. The input on channel 2 is normalized from CV on channel 1 when nothing is plugged in.

4 CV2 A second CV input for amplitude modulation, without attenuator

5 IN Input for Audio Signal

6 OUT Output for the Audio Signal
