What
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-.
How
Dreamer suggested this circuit ; https://www.cgs.synth.net/modules/cgs33_matrix_mixer_euro.html *archive*
This shows a mono 4 to 1 summing mixer, which would be adequate. As i have 12 digipots in home, not 16, i'll adjust it to 3 to 1.
My idea is to end up with 2x the input (buffer) circuit, and 4x the output (mixing) circuit, so i end up with a 3x2 matrix mixer.
After this version works, i want to remix it to a cheaper version, using FM62429 as digipots perhaps, and have the dual voltage regulator on the pcb?
Components
- 2x Input boards 'row board'
- 4x Output boards 'column board'
- Power Supply
- Input and output connectors
- SBC part to operate the digipots, and receive the second stereo output
Stuff to get
Input boards
This gets 3x mono inputs.
Resistors
- 3x 100k
- 3x 1k
Capacitors
- 2x 10uF 25V
- 2x 100nF
Opamps
- 3x TL071 , or 1x TL074
Huh
- 2x Ferrite beads
Output boards
This gets 3x mono outputs.
Resistors
- 6x 100k
- 1x 220R
Capacitors
- 2x 47pF
- 2x 100nF
Opamps
- 2x TL071 , or 1x TL072 (or as i need 4x these output boards, 1x TL074 and share half to second output board)
Others =
- connectors , ???
- some powersupply? (this circuit needs -15, 0 and +15V) , maybe this meanwell
- some kinda case?
- some SBC with line-in and network (and storage?) :)
