Sorry about my stupid questions :
For what is a speakerlink input on the 861?(one on the IE44 two are on the ID26
Speakerlink in my understanding is a symetrical digital signal(music) combined with the communication line and the sense is to feed the DSP.So now its a input on a source?...??
And two inputs on a OUTPUT card??

And the standard SPDIF inputs on the IE44 are 6 channel-not 8channels?
Why makes M a 6channel input card and delete his own source for that-the 800???

Please take some light in my confusions..
