Hello. I have two BIII's with the sidecar and the 4x S/PDIF. Leonvb's guide is great, and has been a great help. I figured out how to wire the units for Dual mono, but not with the Sidecar and the 4x S/PDIF module. Does anyone have a easy solution for this? Thanks!

Just put two IDC connectors where you wound use one on the ribbon cable. One connector for each DAC.

Thank you for your reply Russ.

I have two questions regarding your solution.

Basically, I'm understanding your solution to be something like this...

S/PDIF 4x -> Sidecar -> BIII-1 (DIN) -> BIII-2 (DIN)

1A) My first question that I have is that in Leonvb's guide, he said that the I2S lines for dual mono should be the same length from the source. Would this be a problem?

1B) Also, for the S/PDIF switching, I'm guessing something similar?

Input_Selector_Switch -> BIII-1 (EXT_IO) -> BIII-2 (EXT_IO)

2) My second question is that by connecting the two EXT_IO of the two buffalo's together, the 3.3v supply will be connected with each other. Would this be a problem as well?

Thank you for taking your time out. I really appreciate it!

1) This will not be a problem at all.
2) No you would only wire to one EXT-IO and only use one of the DAC controllers.

You would then disable the port expander on the DAC without the controller. I believe there is a section on that in the guide.

Thank you Russ, for taking your time to respond. I understand you are very busy.

I will try it out...
