3DVCA

Designed to be a highly customizable connection matrix, 3DVCA packs a boat load of utility into a small 6HP package. Four VCAs share the three macro controls: X, Y, and Z. As a group, they shape incoming or outgoing signals and emulate the coordinates of a point in 3 dimensional space. They allow the VCAs to work together in mono, stereo, or quad configuration and accomplish a variety of mixing, crossfading, or panning functions. For easy integration with multiple 3DVCAs or other mixer modules, each VCA output has a dedicated sum input. This allows an entire mix to be automatically passed along to the next mixer in the chain. Each module is built with high quality components, Sound Semiconductor VCAs, and rail-to-rail OPA family op amps. On top of that, each VCA is fully DC coupled to work predictably with any type of signal you throw at it. Exponentially expand the routing potential of your modular system with the Mystic Circuits 3DVCA.

Designed to be a highly customizable connection matrix, 3DVCA packs a boat load of utility into a small 6HP package. Four VCAs share the three macro controls: X, Y, and Z. As a group, they shape incoming and outgoing signals and emulate the coordinates of a point in 3 dimensional space. This allow the VCAs to work together in a mono, stereo, or quad configuration and accomplish a variety of mixing, crossfading, and panning functions.

3DVCA is designed to be used in the following functions:

- Quad monophonic crossfader

- Dual stereo crossfader

- Stereo balancer

- Stereo VCA

- Mono to stereo panner

- Unity mixer with up to eight inputs

- Quadraphonic panner

Each output has a dedicated SUM input which allows an external signal to be automatically mixed into the output signal. This allows 3DVCA to daisy chain both with other mixers and other 3DVCAs. For example, you can create a full mono, stereo, or quadraphonic mix by plugging the output of each 3DVCA into the sum inputs of the next 3DVCA in the chain. Using this method, a set of 3DVCAs can create a fully voltage controlled and decentralized mixer which ties together anything from a small skiff to a monster synth.

When 3DVCA works as a crossfader or panner, the X and Y parameters follow an equal-power curve that keep output signals at the same volume no matter how many inputs are mixed together. This is in contrast to the Z parameter which follows a linear curve to always behave predictably with external modulation sources. All inputs are fully DC coupled in order to work with modulation speed signals as well as static DC voltage sequences; this means that 3DVCA can handle any sort of signal that you throw at it. All op amps in the device employ rail-to-rail inputs and outputs to enable the largest headroom when mixing many different signals together.

Whether you need to maximize your mixing functionality in the smallest possible footprint or have the most control over every aspect of your system, 3DVCA provides a ton of functionality in any system.  Enter a higher dimension of sound with the Mystic Circuits 3DVCA.
