spdif begginer

hi , today i tried the spdif (digital)connection for the first time , my question is:
is there an option to insert more than two (left/right) channels into the bigmixer ?
i mean , my module sends 6 channels through the spdif , can i insert them seperatly into the mixer ?

I seriously doubt that your module sends 6 sep. channels thru an spdif cable as spdif is 2 channels only. So the answer to your question is no.

...also have an s/p-dif question...

<hr>
do i need a dedicated cable, or is every coax-cable like used for tape-decks etc. ok?

gruß & dank,

Mo

well , someone told me a normal coax 75ohm cable should do , i took a cable and made it myself and it works great and sounds great.
the more pedant people would say you'll need a good cable for it (which costs around 40$ in israel) which is always true.
but the budget my friend the budget ...

You can make a proper spdif cable by soldering rca plugs onto 75ohm cable. You'll be able to solder the center lead but the braid will have to be crimp because it is next to impossible to solder to the aluminum braid. There is 75ohm single layer sheilded coax you can get that has copper braid and it solders very well.
While it is true that almost any rca patch cord will work, you should take into consideration that when slaving to spdif, your actually running your system off of the clock picked up from the device the spdif cable is providing the connection to.
This clock is one of the bases of your systems fidelity, and using a non 75ohm patch cord has a degrading effect on the quality of the leading edge of the clocks signal. This in turn can induce jitter relate edginess to your system.
