Hi Brian Thanks the 4:1 Mux/Demux has arrived, now for the questions :) I want to switch the Mux/Demux using my arduino controller and assume I need to do the following to make the unit switch channels; Take 1 GPIO, say Pin 7, from the Arduino to SO Take 1 GPIO , say Pin 8, from the Arduino to S1 Switching: Pin 7 High, Pin 8 Low Pin 7 Low, Pin 8 High Pin 7 High, Pin 8 High Pin 7 Low, Pin 8 Low If that is correct can you tell me which channel will correspond to which configuration. If that's not correct can you tell me how I should be doing it. Edited by user Tuesday, March 24, 2015 6:18:30 AM(UTC)

(Wishing I could insert an HTML table...) It's a binary progression.
For B1, S0: Low, S1: Low
For B2. S0: Low, S1, High
For B3. S0: High, S1: Low
For B4, S0: High, S1: High

Hi,
I'm trying to do the same thing, but the switching doesnt work.
I have S0 and S1 directly hooked up to GPIO-pins from the arduino (5V).
Do I have to remove R2 or R3 on the MUX-board?
Or is a voltage divider for 3,3V required?

No you don't have to remove R2 & R3 No voltage divider is needed The red & black beside the blue & black are the 5V power & power Ground, the Blue & Black are to the GPIO pins on the arduino Edited by user Sunday, May 10, 2015 9:41:45 AM(UTC)

Thanks! The wiring was correct, but I simply forgot to set the right register in the DAC for Spdif  It all works perfectly now.
