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". For more information visit:

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
