Be happy to, but I dont think a photo would really explain things, as I just have a couple TRS snakes plugged into it, straight to a patchbay.
So for inputs 1, 2, 3/4, 5/6, and EXT 1 and EXT 2 are wired to the patchbay (10 total channels). I have a Moog synth half normaled to channel 1, an AKAI s900 half normaled to channel 2, a P6 on 3/4, DT on 5/6, and then outputs from my soundcard normaled to EXT 1 and EXT 2, for DAW playback.
For outputs, I have the Main L/R, Bus B L/R, Foldback 1, and Foldback 2 going into patchbay. All of these are half normaled to inputs 1-8 on my soundcard. The monitor outputs (XLR) go straight to my monitor amp, I use the SSL monitor section (it’s awesome).
I have my eyes on a DB25 patchbay in the near future, this will let me utilize the inserts and alt inputs.
Because I use a patchbay, I can reconfigure the inputs and outputs easily, send other synths to the EXT ins or my outboard verbs etc.
A lot of the time I have the Foldback outs patched to a reverb and phaser, and then those come back in to my soundcard. I can sum them using UA Apollo’s Console, and then bring them back into the SiX via the EXT 1 in or EXT 2 in. This kind of hybrid setup makes expansion of the SiX really easy, while I lose analog summing of those channels, I still get everything running through the bus comp.
PS - the SiX mono inputs have dedicated line in/mic in jacks (no combo) so you can keep a mic plugged in all the time. A switch determines if the line in or mic jack get used. Little touches like that make it a brilliant box
here’s a pic of the how i have the 6 primary channels wired
