I probably missed it in the documentation (duh), but on an SQ6 how does one setup slink sockets on a DX168 as stereo pairs? The SQ6 setup / mixer config / input stereo screen only seems to set up stereo pairs for the local SQ XLRs. I have a DX168 with several stereo sources attached, and want them to patch/operate them as stereo (on one fader strip).
