Optical In question

[d6jg]

I guess this relates to a number of WiiM models.

I want to connect an analogue source to a 24/192 ADC and then split the Optical output from it in 2 directions. 1 to a WiiM Pro and the other to a 24/96 Optical to USB converter and into a PC.

The question is what resolution will be received by the WiiM? Will it be 24/192 or will the existence of the 24/96 Converter force it down.

Anyone have any view?

I haven't tried it myself, but I guess the WiiM's Optical Output Resolution must be set to 24/96 for audio signal to pass through the OPT to USB converter.

If the splitter is dumb, I’d expect the 24/192 resolution output from the ADC to be what the WiiM receives on its input. I’d guess the question is more about what the optical to usb converter does when presented with a higher resolution than it’s specified to handle - I’d guess it might simply not work unless it can downsample.

I think they are generally dumb and have no electronics in them at all - presumably just a mirror or two. The ones on Amazon don’t specify any resolution. So my thinking was the same as yours.

And yes you are right the splitter is going to be ahead of the WiiM input. The WiiM output will be analog.

WiiM output is not in the equation. It’s intended to be split before input with the Optical to USB on one output and the WiiM on the other. A branch line if you will,
