Use of Word Clock In 3

[Anupc (Anup)]

I’ll await an official response from dCS on the clocking question.

Sure, you might want to tag @Phil (that said, the manual already tells you that you’re going to get improved performance).

Word Clock In3 is primarily intended to be connected to the Upsampler’s Word Clock Output to improve performance with sources that do not have a Word Clock input.

If you need deeper technical explanation for why, I suggest you read the read James’ excellent explanation

dCS Ring DAC - A Technical Explanation

Part 4 – Clock Synchronisation There is a problem posed when multiple digital audio devices, each with their own internal clocks, need to work together. Take the example of feeding a CD transport into a DAC. The DAC has a buffer – a section of temporary memory which stores the audio samples it receives from the CD transport. The transport’s clock dictates when a sample is sent out to the DAC, and the DAC’s clock dictates when the sample is used and converted to an analogue voltage. In an ideal…
