Quad Attenuator/Mixer/Add,Sub/Saturator/Inverter

Very high fidelity, low noise, precision attenuator, inverter, mixer, adder/subtractor and customizable saturator.
Four channels with individual in/out, inverter switches and RGB signal polarity indicators.
Extremely low offset and distortion allow MIXMODE to be used as a precision adder/subtractor, with less than 0.2% standard error.
Final output is switchable to a mix of all four channels. optional expander adds dedicated mix outputs.
Two final mix circuits - custom saturator and high headroom (rail to rail). PCB trimmers allow for custom user saturation settings (bias and symmetry). Optional expander brings saturation controls to the front panel as well as voltage control over those parameters!
