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)
By replacing the decoupling capacitors with a wire, it can also process CV signals.
The Original concept was designed by Tom Wiltshire aka "Electric Druid". [more info]
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
Customer Reviews
Seeds look good! Thank you!
Great small company making amazing modules.
They're also very helpful and have been answering to any of my questions during the building process, making for a really rewarding experience!
Easy build, works great, looks great. Note: AC coupled (I use it for DC blocking output, you can make it DC by bypassing the 1 uF cap.)
Jamais déçu par ce vendeur, au top !
Absoluut top notch high quality module from Ruben and Tom. Easy to build (all through hole) with readily available parts. An elegant design. Highly recommended!
