the 7000 has no routing options. Being a stereo machine, it expects to work in this way or in mono>stereo mode. There are presets that already work fine in mono>stereo. The true stereo ones though require the use of Vsig for input mod or connecting a "Y" cord to both inputs. Do not use "Y" cord on the outputs though! It may create problems. Full mono use requires Vsig mono I/O configuration.
all the best
