Can someone explain the clock sync?


I recently got a new Denafrips Terminator 15th. I already have the Denafrips Hermes so I can sync the clocks with 2 BNC coaxial cables. I have done that but I really am not positive what this does. I did it right away when I placed the DAC into the rig because this DAC is a beast to move and make connections so I just did the connections and let it cook. All my digital sources are fed into the Hermes and I use an I2s connection to the DAC as well as the clock cables. I scoured the internet with google to find out exactly what this does to no avail. Maybe someone here can explain it? All I can gather is the two clocks "talk to each other" but does this allow the better clocks in the DAC to take president? I’m old and this digital stuff is complicated to me in some cases. Thanks!

The sync clock for digital isn't the same as the syncing to movie's 29 frames per second or TV's frame rates together such that the sound and visuals are synced. That is called SMPTE timecode.

PS - Never meant to imply it was the same thing.  Just that when mastering a multichannel movie you may have even more devices to keep in sync than stereo mixdowns.

@kairosman  I missed your question about the Terminator 15th being a rebadged Terminator Plus. It seems to be the case from all that I can gather-it is the same other than the faceplate. It is also my understanding that the 15th engineer team did some programming enhancements through the FPGA, but I am not positive. It is surely about the Terminator II level which is now supposedly the new Venus 15th. 

@fthompson251 wow 👌 if that is the case then your 15th and the Venus 15h at $3700 are smoking deals. Tempted but thinking of the new Weiss DAC502 Mk II because of the DSP functions.

@fthompson251 Since they rebadged the Terminator plus to the Terminator 15th are they going to create a new Terminator plus?  The Terminator plus is still for sale on the website.

@brbrock Well I can only go by what I was told by the dealer I bought my T15th from and at this time there are no plans for a Flagship DAC, maybe in a few years. So the Terminator15th IS the flagship. It certainly sounds like it to my ears. I understand that Denafrips still has some of the T+ Faceplates they want to sell off.  I think that is why they are tight lipped about the T 15th detailed specifications, they lead you to thinking it is a replacement for the old Terminator II, but that is basically the new Venus 15th. At some point they will be forced to spill the beans to make all the models make sense.
