Using Rossini Transport With Lina

dCS Products
1

My Rossini Transport arrives today and I have been reading the manuals like a good boy! Looking at the Lina manual there are only clock inputs and no output. Does this mean I cannot connect the transport to the Lina in master mode? The diagram in the Rossini transport manual shows the connection going from the Rossini dacs clock output to the transport’s clock input but there is no output on the Lina.

Thanks and I hope that makes sense!

The Lina does not have a Wordclock out, but you can slave it to the transport using the Wordclock out of the transport connected to one of the Wordclock ins of the Lina.

Then for AES1+2 set up to slave to the correct WC.

Hi John,

Exactly as August says, if you are connecting the Rossini Transport to the Lina DAC and you do not have a Clock (like the Lina Clock) in the system, take the Wordclock Out from the Transport and connect it to one of the Wordclock Ins on the Lina DAC.

Then set the Lina DAC to the input you are using, likely Dual AES, and change the Sync Mode setting to Wordclock Auto:
Lina Wordclock Auto
(You can do this from the front panel of the Lina DAC by going to menu → Device Settings → Sync Mode)

Thanks both, now I know the answer is going to be “listen and see” but in theory is it better to use the Rossini clock output rather than the Lina one?

As the Lina DAC doesn’t have a clock output, the only choice is between using the Transport’s clock output or not using a clock connection at all.

It will still work without the clock connection in place, but it will definitely sound better with it.

Hi John,

You must sync the two clocks (DAC and transport) to avoid clicks and pops. In your configuration you have two options:

  • Slave the DAC to the transport using the WordClock Out on the transport to one of the WordClock Inputs on the DAC with a 75Ω coaxial cable as August and James have said.
  • Slave the DAC to the transport using the clock embedded in the AES data stream (no separate clock cable).

Of the two the former is definitely the better option as it avoids the problem of inter-symbol interference.

James beat me to it.

Perfect… I don’t understand it but will connect it as advised! It looks like he bnc should be in the box. Thanks again everyone.

OK, all hooked up and seems to be working ok.Lina display says w1 and dual aes. DSD. One question though, does selecting upsampling in the Lina (DXD DSD DSDx2) effect the sacd playback or is it always DSD?

10

Great!

The latter, native DSD is never upsampled.

11

Thanks! Sounding pretty good so far though I needed to leave it an hour after delivery because it was so cold it had condensation on the case!

12

Although it is true that DSD is never upsampled I am unsure that this is exactly what @Ryder35 is asking.

With hybrid SACDs ( most of them) the user can select between the SACD ( DSD) layer or the CD layer (PCM). Select the Rossini Transport menu, then " Settings" and then the layer page.

Hi Pete, I was actually asking about the sacd layer, what confused me was the mosaic app allows me to change the upsampling mode on the Lina even when an sacd is playing.

14

Thanks. Mosaic system control does not know what layer you are playing so the upsampling options shown remain available. However DSD, in whatever form ( SACD disc layer, local file) ,cannot be upsampled as @AndrewS pointed out. Of course you can upsample the CD layer of a hybrid SACD disc.

I hope that you are enjoying your new transport. In my case it followed Verdi and Paganini transports yet , as excellent as these were, I found the Rossini showed me a world of listening that I had never anticipated.

Thanks Pete, loving it so far!

one more thing is confusing me. I now have upsampling settings on the transport and the Dac, so say, for example the transport is set to upsample cd to DXD and the Dac is set to DSDX2 does that mean it gets converted to DXD, sent to the Dac and then converted to DSDX2?

16

That is something that I have never considered. However why would you want to do this anyway ? You can use the transport to upsample directly to DSDx2. No meed for any interim stage of DXD.

You can also upsample PCM directly to DSDx2 in Lina. You may be right from a conceptual viewpoint but either way the result is the same. You get DSD128. No need for two lots of upsampling.

See your user manual. Page 24 but you may have more recent edition than mine.

As regular readers here probably know I don’t use upsampling in any case but I think that this is only possible with Vivaldi.
