I have a DIgital series 6-Channel. Currently I have only one (1) Symbilink cable. In the manual, it shows only one cable going to the amp for a front stage and subwoofer set-up (mid-range and up on ch. 1/2, mid-bass on ch. 3/4 and sub on ch. 5/6).

Currently I can only get a signal to the channels that I plug the cable into.

Is there a setting on the digital programming that will fix this or do I actually need all three Symbilink cables???

Thanks
