Mix, amplify, clip, invert…..Volts Platz has it all.

A year or so ago I stopped selling System X CV Mixer. People keep asking for it, so I added a few features, changed its name, and now it’s back!

Volts Platz has 4 inputs with attenuators. Input 3 is normalled to +ve for positive offsets (up to +8V), input 4 is normalled to -ve for negative offsets (down to -8V)

The first opamp stage now includes a switch to select x1, x2 or x10 amplification. You can take a direct (inverted) output from this stage.

The second opamp features switchable clipping diodes (LEDs) which clip anything above/below +/-5V. So ‘normal’ Euro signals go through unaffected. Flick the amplification switch and things gets dirty.

Patch a post-VCF signal into input 1. You can then use a combination of offsets at inputs 3 and 4, and CV into input 2 to explore modulated symmetric and asymmetric clipping.

Scale, offset, amplify, clip. Or just use it as a 4 input mixer.
