Acquisitio 4-Channel VCA + Offset

ERD Modular Acquisitio

Acquistio from ERD is a four-channel voltage-controlled amplifier with offset and subtraction controls, built for precise control over CV signals to take your other modules to new heights of geomantic expression. As part of ERD's geomantic toolkit, Acquistio is a crucial component of any system that can appreciate a high level of control over CV signals, particularly for analog computation modules like ERD/TOAD. Even if you aren't experimenting with ERD's geomantic discovery program, any system will benefit from the control provided by Acquistio, empowering modulated modulations of sought-after sweet spots in all your parametric sound effectors and affectors.

On Acquistio's left side, inputs for four VCAs are provided, along with a knob for CV amount. The second and fourth repetition of this circuit double the VCA gain, while the first and third offer voltage controlled attenuation. On the right hand, signal inputs for subtraction are provided for each channel, as well as an offset knob control and final output. Put together, these utilities offer precise control over CV signals through simple voltage math, extending beyond the capabilities of typical VCAs. Whether you are spelunking into the depths of patch programmability and feedback control with esoteric operators, or simply need a high quality VCA to get your filters and other modules wiggling with precision, Acquistio from ERD is a great addition to any system.
