The Paperface Dual Mixer is a simple 4 x 2 channel mixer that offers 3 attenuated inputs and 1 single unity gain input per-section. With the option of having 1/4", 3.5mm and banana outputs, or both (depending on how you build the module) allows some great feedback patching options.
You will need to determine if you want to use 1/4" jacks or 3.5mm jacks. BOM includes 1/4" jacks. 3.5mm jacks can be found HERE
NOTE: Panel will need to be drilled out for the 1/4" jacks before any paper panels are mounted to the panel. 3.5mm jacks DO NOT require any drilling.
Follow the General Build Guide for this module. Requires no setup or calibration.
