Eleven Rack Split L/R Distorts

[martinaston]

I like the Eleven Rack; however, I have encountered a problem which I cannot seem to solve. When I record in to PT9 using the Split L/R configuration to record a dry guitar track, no problems recording in, but when I listen back to the take (no plug-in processing introduced at this point), the "dry" signal exhibits distorted artifacts which completely ruin the purity of the dry signal and thus obviously the take. I am connecting to 003 Rack via SPDIF output from Eleven Rack.

As an experiment I have tried using a Line 6 UX8 through the same 003 Rack SPDIF input, and no such problem occurs so I have narrowed it to either the design of the Eleven Rack itself or possibly that my unit has a fault.

Any information would be gratefully appreciated.

Many thanks
