Hello guys, That s my 1st help need
Well, I ve got Luna II, I see a spdif but damn, I ve never understood how to use it :
Is it only for the clock, or U can use it as digital input or output 4 audio???
If yes, how, I don t really realyzed with which cable, do I need a simple metal jack (like ipod headphones...)or optical Jack???
That s because I ve never saw a spidif with a jack connection, usualy it s rca or aes ebu
Last question, if spdif can be used as in out , do I need to set something on sfp routing win ? tnx a lot for help
Cheerzzz

Im Pretty sure It Acts as a In and and out (DIG IN / DIG OUT), I have a pulsar 2 and in the Scope Routing window there is " SP/Dif - Source" and "SP/Dif - Dest" connected to the mixer. Haven't Tested the Port yet , I will next week When my Virus TI gets here.
Edit:- The Cable you need is Just a Unbal RCA Stereo. You Should only be plugging other devices with the SP/Dif interface into it, It can not Convert Analouge to Digital so there should be no cables with metal Jacks involved

well, if everything would be that easy...
the cable with the ministereo-2RCA may (seem to) work, in particular if it's very short. But it can in no way be guaranteed - S/pdif requires a 75 Ohm certified cable, and afaik no such thing exists with the connectors shown above.
the usual approach would be to use the adapter from picture 1 plus 2 certified cables for digital audio.
The (cheaper, often yellow jacked) 2xRCA video cables for 'multimedia' also seem to work (at least they ARE 75 Ohm).
I once tried a 2m 'regular' audio cable and it was the perfect emulator for vinyl surface noise
just listen closely...
cheers, Tom

yes, the Luna can do the s/pdif round-trip (for fx processing) trick - my Pulsar One cannot.
If you want to send the s/pdif signal to your monitors, you'd need the adapter anyway, as it's just one (output) cable and the (first) monitor passes it on (at least on my DS30).
You will not want to have the (empty half) receiving cable dangling around unconnected. It will catch even more Poltergeists and most likely influence the parallel (sending) line.
In that constellation you cannot use the 'receiving' part of s/pdif, if Scope is the clockmaster (which usually is the case).
you'll have to sync Scope as slave to the sending s/pdif unit (and keep the latter powered) if you want to send and receive from different units.
this may read a bit complicated, but it's absolutely logic - it's the flaws of the s/pdif specifications.
cheers, Tom
