S20 not sychronizing with Weiss DAC202 DAC

Support

I’ve acquired and connected a Weiss DAC202 DAC to my S20 reclocker via AES/EBU for the digital signal transfer using the internal DAC202 clock and everything works fine.

When I connect the S20 to the DAC202 using a high quality 75ohm BNC cable and configure the DAC202 to receive an external clock, the S20 and DAC202 do not sychronize and there is no sound out of the DAC.

What’s wrong and how do I fix it?

When you connect a coax to the SPDIF output of the S20, the clock and data are both passed through the SPDIF cable. I’m guessing that by telling the 202 to use am external clock, it is ignoring the clock signal passed over SPDIF. If you revert that clock setting, does music play?

Hi Kenny -

Thanks much for looking at my situation. I haven’t tried the BNC or RCA SPDIF connections on the S20. I’m using AES/EBU connection via XLR cable for the digital signal.

The two units are connected via AES/EBU (S20 AES3 XLR output connector to DAC202 XLR input connector) for digital signal, and coax BNC for word clock (S20 Word Clock BNC connector to DAC202 BNC word clock input connector).

There are technically 3 options for clocking on the Weiss DAC202: 1) internally (i.e., the DAC202 clock), 2) via the digital signal (in this case, via the XLR cable I’m using for AES/EBU digital signal), and 3) an external word clock via BNC (in my case, I’m attempting to use the S20).

With the two cables connected, the DAC works fine via clocking options 1 and 2 (internal DAC202 clock and through AES/EBU digital signal via XLR). When configuring the DAC202 clocking source to option 3 (external with the S20 via BNC), the DAC202 sits ‘unlocked’ and sound doesn’t pass.

The BNC coax clock cable is a 75ohm 0.7M Oyaide DB-510 that’s directional, and I have connected the two in the correct cable orientation.

I’m using the S20 BNC connector labeled “Word Clock” to connect to the DAC202 work clock input. Is this correct? From my above description, what ideas do you have for what’s going on? I find no way to access S20 settings via the S30/S40 control panel.

Thanks

I’ve never heard anyone report that they were doing #3. Doubtful that there would be a benefit as it’s the exact same clock as what’s being passed via AES. I would just let the AES cable pass the clock. Not sure you gain any benefit.

Ah, ok then. That does work, and the sound is very good, so I’ll go with that. Thanks for having a look and advising on what to do with my situation.
