The signal is def going into the lexicon and is in sync because the digital lock light is on but only 1 channel by the looks of it.
in SX3 on the external fx page ive added an fx bus but where you assign the output theres an option for both L & R channels, the only choice's ive got for the S/PDIF connection is 1 input & 1 output & it wont let me put an entry in both L&R. I was under the impression that 1 S/PDIF cable carried a stero pair so why does it ask for seperate outputs if im not using the analogue?
Ive got the output from the Lexicon routed back into a second input bus and theres def norhing coming in.
