Intellijel Designs DUAL VCA 1U

The Intellijel Dual VCA 1U packs a pair of high-quality DC-coupled linear VCAs in a compact 1U package. Because they are DC-coupled, these VCAs are suitable for use with CV or audio signals. These can be used independently or together with normalization. When OUT A is not patched, it normals to sum with OUT B, with independent control over CV A and B. CV A normals to CV B with nothing patched for stereo processing or CV pairs. LEDs indicate the level of incoming CV signals.

Dual VCA 1U
The Voltage Controlled Amplifier or "VCA" is one of the most essential and useful building blocks in a synthesis patch.  The DUAL VCA 1U packs two high quality, DC coupled, linear VCAs into a very compact 1U package.

The two VCAs can be used completely independently or in tandem via the handy signal normalling.  The DC coupling means that the VCA can be used for the amplitude control of both control voltages (CV) and audio signals.

Some application/use examples:

Dual, independent VCA for dynamic level control of two different audio or cv sources
Stereo VCA (use the CV normalling where CV A normals to CV B) for processing stereo sources or CV pairs.
CV/Audio summing  (when Out A is not patched, it normals to sum with OUT B,  CV A and B control the independent levels)
Voltage/signal doubling (use input A only and the doubled voltage will appear at OUT B when a CV of +5V applied to CV A)
