BL50 Coaxial input

[YannChris]

Hello Beoworlders,

Still testing my 50s, I borrowed a streamer (Wiim Pro) to try the coaxial input, as it goes further than the optical one in terms of resolution (192 kHz vs 96 kHz).

Unfortunately I get no sound when playing a 24 bits/192 kHz file, as well from Qobuz or from NAS.

Checking in the technical sound guide, I noticed:

“Optical connector: Standard sampling rates up to and including 96 kHz,

S/PDIF: Standard sampling rates up to 192 kHz,

USB Audio: Standard sampling rates up to and including 192 kHz.”

Should I understand that S/PDIF input does not support 192 kHz files?

Did anyone made the test with such files and what were the results?

Kind regards,

Yann.

Yann,

The BL50/Wiim should handshake together in terms of sample rate.

Have you configured the BL50 to accept coax/optical?

BL50 >> Configure >> input >> three Dots >> Powerlink No.1, SP/Dif or Optical to No.2 >> Listening Preset and Time Out adjusted

Also, because this is a digital, you may need to ensure the BL50s are switched on via a remote (as well as powered on). Because I use XLR, I use the Detect Threshold setting to trigger my BL90s. This is not required on digital sources but somethings up not causing a signal on?

Thanks Mr 10%

Yes, everything is configured as you stated. Wiim is configured to a maximum rate of 192 kHz on Coaxial out.

I do not use Optical for this test, as this connector is limited to 96 kHz on the speakers.

With 96 kHz file, the coaxial input works normally. With a 192 kHz file, no sound.

The BL50s switch-on on both files.

I checked with a brand new cable, same result.

Kind regards,

Yann.

if you haven’t yet, try googling Wiim Pro coax 192khz……cant say for sure, but there seem to be other Wiim users who have (had) the same issue.

[YannChris]

I did, but no solution.

Most posts on the subject are optical-related.

Hello,

I have the exact setup: WIIM connected to Beolab 50. Initially, I faced challenges achieving consistent results while checking high sampling rates via Qobuz. Interestingly, using an optical cable allowed me to play 192 kHz files without issues. However, when I switched to a coaxial cable, I couldn’t play the same files and I had to set WIIM to 96 kHz. But later I replaced that cable and it worked at the highest setting since then, although it took several tries initially.

I have to add that I don’t think 192 kHz sampling rates add anything useful to my ears.

How long is your S/PDIF cable? Some streamers will not output at 192/24 over longer cables, though most will.

[YannChris]

It’s 5 meters long.

1st test made a cable supplied with Beolab 5s, connected to the SP/DIF out of a Beocenter 2, as I had no problem with this cable with this configuration.

So I suspected the cable and bought a brand new one, with the same lack of result.
