THAT2180 based VCA

Part of the Takaab range of modules by Siam Modular.

An exponential (dB) gain voltage controlled amplifier for eurorack modular systems. This is a flexible module with wide-ranging controls to suit various applications. Includes two signal (audio or voltage) inputs, two summed attenuated CV inputs and bias control.

Size: 2cm x 128.5cm x 5.2cm.
Runs off +/-12v standard eurorack power supply.
Package contents: 1x module, 1x 10 pin power cable, 2x M3 screws.

Usage notes:

Bias control goes from -6v to 0v. Position fully clockwise for +v/-v tremolo style effects, or position below halfway for use with envelopes or other 0v/+v control voltages.

Because of the range of the CV gains it is possible to distort the signal depending on the input levels. This can be desirable, but usually with a hot eurorack signal, setting the CV around half way is a good starting point for good amplification without distortion.
