Hi,

Yesterday I did try MAX size and then 28 and still no sub action at all. Yes the cables are certainly connected to the right card (#1) and outputs (3/4).

I thought I have tried everything really over the whole day yesterday apart from changing the cables. The cables were bought brand new from a company who sells just that...cables. I doubt both are faulty.

The only thing that really stands out is that when in speaker calibration in M Config when uploading the file it will come up that all speaker couldn't connect to the 861. Well of course all do apart from the sub so there is something going on that eludes me.

Also this probably doesn't make any difference but the cards in the back of the 861 don't really correspond to the graphic in M config. e.g the CO00 card is listed next to the power card but actually it is about 3 card spaces away. Although the cards are in slightly different positions they obviously all work etc so I guess it really doesn't matter what positions they are put in then. All work except the sub of course.

Thanks
