| iToolBox has facilities for designing multi-layer PCBs, complete with Gerber output. This is the PCB for my mixer design. |
It can be configured for 8:1 stereo mixdown, or for 15:1 monophonic mixdown. Inputs can be configured as either AC or DC coupled. Outputs can be configured as either AC or DC coupled as well.
Typically the mixer is built for unity gain as the intent is to mix, not to amplify, but it can be set up to have any reasonable amount of gain above unity you desire, including different gains on each channel or pair of channels.
The mixer requires +/- 15 VDC for minimum THD, maximum dynamic range, and lowest noise. However, it will operate with supply voltages as low as +/- 12 VDC.
I sell these PCBs as a bit of a side hustle.
