The master clock and bit clock lines seem to be the most sensitive to cable type. I used mini coax for the master clock lines and ribbon cable for everything else
Grounding is very important too!

Shouldn't each connection have its own ground line ?
But on the COD board there is only one ground pad........

Ok, I've just ordered two COD modules. Can't wait to assembly them with my WaveIO USB-i2s module, i/v active stage and power supplies, and start listen to some good music ! 
Hi all,
I'm attempting to connect the TP 4:1 MUX receiver to the COD.
For the 'MCK' connection on the MUX where does this go on the COD, to the 'SCK' terminal? Does SCK mean system clock, is it necessary?
Thanks in advance and excuse the digital ignorance!

okay, I'm assuming that MCK = SCK (master/system clock respectively).
even hooking these together I'm still not getting the lit lock led.
I'm using an older CD transport that may not do more than 44khz but I'm confident this isn't the problem since the same transport works well and without issues on other dacs.
Voltage is ok and checks out. 7.5VDC to the 4:1 MUX and 5.5VDC to the COD (DAC) and I'm only using s/pdif coax from the transport since I don't have anything else. Furthermore the switch on the MUX is switched "closed" for enabling input '1'.
Is there a recommended procedure in troubleshooting the MUX?

Yes - SCK is equivalent to MCK.
Any chance you can try a different SPDIF source? Also please move this to the support forum if you can and provide some pictures if possible.

is there a specific forum for this combination? All I had found was this thread and another for the MUX, but nothing caught my attention for a "support-specific" thread so I guess I high-jacked this one.
Photos shortly following.

Quick update:
I'm not able to upload multiple photos here.
In the meantime I have assembled the s/pdif module and have tried an alternative s/pdif source without success.
The mux its on top the dac module. Let me know of you need to see something specific that isn't visable in the photo.
Thanks

An externally hosted image should be here but it was not working when we last tested it.
