View Full Version : Tag sync link

Just a quick one, is there any reason why a digital coax wouldnt work or may not run properly for sync linking?.

Only if there was a major impedance mismatch, it should be a 75Ohm link IIRC.

cheers mudge :)~:-)~:smile: Tag recomend using analogue cable but its going to be easier to get another pukka scorpion coax.

Ah. Unfortunately I'm not entirely sure of the specific method used to implement the sync link. It's conceivable that the sync clock works at 1/8th of the bit clock of the S/PDIF in which case the impedance might be wrong at that frequency.
However I'd be willing to bet money that one of Groundy's interconnects is closer to the correct impedance at whatever frequency is used, than for an analogue audio interconnect.

nice one mate, for the money its worth a go :thumbup: I might as a thought give Tag a mail see what they say.
if a digital cable is screened correctly there is no reason why you could not use it for sync link or other analogue purpose. at least for short runs. many companies also claim this officially on their pages.
tag will probably try to sell you their expensive analogue cable as they definitely need money before they tell you digital is fine. btw i saw one dealers' reference tag system where all cables (short runs) were digita.

The Tag needs a good digital lead for the PCM / bitstream connection (read 75 ohm etc etc), the sync link just needs to be a good quality screened analogue lead as it is passing an analogue signal, however this is exactly what the 75 ohm digital lead is, only more so. This is why I and others recommend good quality coax for digital, video and analogue leads!

Thanks Guru and Nic
I pretty much thought a coax would be ok after Mudge explained but i was hoping you would pop in and confirm it being the Tag guy 8)~8-)~:cool:
