I want one.
Does anyone use DSD anymore?
Seems like a "low growth enterprise"

What?  Cities will be designed around DSD!!   Oh wait - that was the segway.

What's that thing sell for?

well no shit, but the real question is what functional reason is there to word clock slave against an external device in this instance? Same as far as slaving something else to this (what circumstances would you reasonably do that).

Im sure in a studio this might be the norm.

You have multiple tracks; some pcm, some dsd.  You'd want them all to be in sync?

So your left would be dsd and right be pcm? (as far as I can tell, these are 2 channel units). Your WC in is going to hit both channels, so one will always be resampled in that case (or mistimed, whatever happens when this stuff goes wrong).

Two WC sync scenarios come to mind:

1) Sychcronizing multiple DACs for simultaneous output of multiple channels (more than 2).
2) Possibly for studio or mastering type applications where a digital signal is being routed through the DAC to feed analog gear, then redigitized for further editing/processing. I imagine there might be a reason to clock sync the converters.. perhaps to calculate & compensate for the processing delay imposed when dealing with parallel processing?

For one - the SDIF connectors used for DSD requires external clock.  Each channel and clock are on there own seperate connector.


i.e. for 2 channels SDIF you need 3 connectors (1 clock, 1 channel 1, 1 channel 2), for 8 channels you need 9 connectors - if you are running multiple 2 channel dac's to decode 8 channel SDIF each dac would need to be using the same clock (possibly why there is a daisy chain capability).


This is the way SDIF has always been - go look at a PCM-2500b - using SDIF - there is clock, SDIF channel 1, SDIF channel 2
 - Note that this is for SDIF (Sony Digital Interconnect Format) and not S/PDIF  (Sony/Philips Digital Interconnect Format)


Update:
SDIF2 requires a 44.1kHz sync signal to be passed to the DAC and this should preferably come from the 1073DPD sync output via a third BNC cable. SDIF3 transmits the DSD signals with clock information included and should not need the sync signal.

I did not know that. Interesting.

I hadn't thought about multiple channels. I guess I'd assumed (which is dangerous in it's own right) that studios would use multi-channel equipment instead of the daisy chain method, but I can see some advantages to that. Right tool for the right job I guess, especially in conjunction with the DSD info.

Thank you both, learn something new every day.
