Vintage Synth Lab AWM-3 Eurorack Waveshaping Mixer Module
The AWM-3 is an all analog, real-time, complex wave-shaping (triple wave-folder) 3-channel mixer module with added features of compression and multiple mix modes including matrix mixes. The combination of multiple access points (outputs of various mixes), wave-folding, and compression allow for an extremely wide array of signal processing, including complex chorus-like sounds.
All three channels are identical and can operate independently. They can also be cascaded (connected in series) to obtain double and triple wave-folding. The compressor at the front-end of each channel allows for not only unique wave-shaping, but the ability to send asymmetrical wave-shaped signals through multiple wave-fold stages while preserving a better managed signal process.
With individual outputs for each channel, a master mix (and master level control), as well as three matrix mix outputs as: “MIX 1+2” (1 OUT + 2 OUT), “MIX 2+3” (2 OUT + 3 OUT), “MIX 1+3” (1 OUT + 3 OUT), the AWM-3 is wave-shaper, signal processor, and multi-mode mixer.
Each channel has independent positive and negative control over wave-shaping, including CV inputs, CV attenuation, bias (wave-fold threshold), and level (wave-fold volume). Each channel also has a dry level control. Between the dry level, positive wave-fold level, and negative wave-fold level controls, many variations of wave-shaping are possible.
All CV inputs will accept LFO or audio-rate frequencies. The main signal path is DC-coupled. Each dry signal throughput can be amplified up to +6dB (2 times the input signal) and has a buffered output.
With the addition of a VCA inserted before the AWM-3 (i.e. VCO > VCA > AWM-3), dynamic wave-folding opens up a high degree of variation for automatic wave-shaping. Add the compressor stage, then new and complex sounds can be generated.
