Hi Flatmax,
Thank you!
Sorry for lots of questions.
1. Balanced breakouts - yes this was what I was looking at and this post based on using this board:

2. Input options: 1/4" or RCA. The 1/4 looks like 3 way (tip/ring/sleeve), so I believe I can go XLR to 1/4" (TRS). Easy. Yes?
3. Additional Preamp for mics - DC15V
Can I connect suitable power supply into the 15V 2.1mm connector on the blue board?
From other threads it looks like that's what it is intended for?
4. Balanced breakouts convert output -> input.
I just looked up the Cirrus chip from your link in the kickstarter and I see this chip is limited to 6 balanced input/8 bal output.
So 6 mics is the limit.
Does this sound correct to you? Or do you think it's possible to repurpose inputs as outputs with a modified driver or otherwise?
5. Run 2x Octo boards at once? - I would like to hook up ~10 microphones.
I would think Alsa would end up seeing two sound cards, which should be fine. Might need to massage asound.rc perhaps.
Any other perceived issues?
