I am buying a WiiM DAC streamer , it has SPDIF and Coaxial outputs but Plybar only has Optical Input. Can I connect the SpDIF Out directly into the Optical input of my Playbar?

If no means I Need a CONVERTER?

You don’t need a converter. Just wire the WiiM to the Playbar and constrain the WiiM’s optical output to 44.1kHz and 16 bits. It might work okay at 24 bits; try it.

As long as it is sending nothing higher than a Dolby Digital codec, you should be fine.

Analog Audio Output

1 x Analog RCA Line output,
1 x Digital optical (SPDIF) output,
1 x Digital Coaxial output,
up to 384kHz/32-bit

1 x Analog RCA Line output,
1 x Digital optical (SPDIF) output,
1 x Digital Coaxial output,
up to 768kHz/32-bit
DSD512

Is this OK?

I don’t think I’ve ever seen Sonos publish the SPDIF requirements, which I assume means all TVs send the same thing. Depending on what ‘up to’ means (do you choose?) I think you’re fine, as I said. If I’m wrong, someone will provide you better data.

It’s not common to connect a DAC directly to a PLAYBAR, they’re normally connected directly to a TV set.

What your specs don’t cover is what codec the output is in. Just frequency and bit rate.

OK I will use a converter to be safe

Honestly, I wouldn’t spend that money until I had proven it didn’t work.

Hello Ratty

Thanks

Will have a look at it when it arrives.

I feel obliged to ask: what are you planning to stream through the WiiM that the Playbar can’t manage itself? It’s not as if the Playbar can handle the high-res content the WiiM is capable of outputting.
