Maybe it would be easier if I tell you what I have and some genuis can tell me where to to connect leads to back of 861

816 V4
Fronts 8K's
Rears 8K's
Centre 5K
D2500 Subwoofer

Here we go....

I have one cable marked FRONT (2 leads - one lead with DIn plug , the other lead with digital out plug )

I have one cable marked REAR (2 leads - one lead with DIn plug , the other lead with digital out plug )

I have one cable marked CENTRE (2 leads - one lead with DIn plug , the other lead with digital out plug) The DIN plug on this cable has a different pin layout to DIN plugs on other cables...??

I have one cable marked CENTER SLAVE (1 lead with a DIN plug)

I have one cable marked SUB ( 1 lead with a DIN plug)

Suggestions greatly appreciated.

I would still like to find a document which explains how these cables are connected...So next time I dismantle or modifty system I will not have to ask again.

Thanks
