BackCommit Dual VCA, based roughly on Moritz Klein's work, but will need painting. Could be glued on with CA or hot glue, if the PCB is used. In loop position, loop\nis connected to trigger, gate jack is normalized\nto +12 V, 10 mA -12 V ## Photos ### Photos ## Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm - rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? SR2511 series are 11.43? Maybe more? Distance between pcb and front panel, horizontal PCB mount, retention spring instead of latch, https://www.neutrik.com/en/product/nc3fav1-0 A Series, 3 pole female XLR receptacle, switching contacts, grounding: separate ground contact to mating connector shell and front panel, horizontal PCB mount, asymmetric push, https://www.neutrik.com/en/product/nc3fbh2-da B Series, 4 pole chassis.
