We've had experience with hardware like this through the Nexia_PM, but thats a very expensive device.

This project aims to make a simple 4x in 1x out (or maybe 2x out) stereo mixer that is controllable over network -only-.


Dreamer suggested this circuit ;

This shows a mono 4 to 1 summing mixer, which would be adequate.

Idea will end up with 2x the input (buffer) circuit, and 4x the output (mixing) circuit

Stuff to get

  • 16 digital potentiometers , possible model X9C104
  • 8 'buffer' opamps , possible NE5532
  • 8 output opamps , ??
  • ferrite beads , ???
  • connectors , ???
  • some powersupply? (this circuit needs -15, 0 and +15V) , maybe this meanwell
  • passives : 36x 100k ohm , 8x 1k ohm , 4x 220 ohm, 12x 100nF , 8x 47pF, 4x 10uF
  • some kinda case?
  • some SBC with line-in and network (and storage?) :)
