The ASM308 is a four-in/one-out bipolar or unipolar DC coupled mixer ideal for mixing control voltages.
When in Uni-Polar mode, all pots behave in regular fashion, that is when the knob is fully counter-clockwise, no signal from the associated input passes into the mix. As the knob is advanced clockwise, a greater portion of the signal passes into the mix.
In Bi-Polar mode, each knob has a zero position mid-way through it's travel. Turning the knob anti-clockwise will add an increasing portion of a negative (inverted) version of the signal at the corresponding input, while turning the knob clockwise will add an increasing portion of the original signal to the mix.
The ASM308 uses the 2 core boards from the CGS733 CV Matrix Mixer
Additional output columns can be added through the addition of one or more ASM308EXT Extender units.
For a 4-in/4-out version readers should refer to the CGS733 4x4 CV Matrix Mixer.
