SubMix

2 x 4 channel mixer

A compact dual four input mixer for both audio and DC-coupled control with sum and difference outputs.

It may be used to combine audio and modulation wherever other modules do not have enough inputs. It may provide modulation to control FM and PWM on a VCO or audio and CV to a VCF or multiple VCFs.

SubMix has balanced or unbalanced compatible inputs and outputs, extending its application beyond synthesizer use to other audio processing such as outboard FX sub-mixing and M/S encoding and decoding.

• 8:1 or Dual 4:1 Mixers
• Sum and Difference outputs
