To achieve a true monaural signal you need to disable binaural mode in either voice assign mode POLY 1 or POLY 2. Once the Super 6 is set to non-binaural mode, set LR PHASE (or PAN in this mode) to 100% so that each voice would be hard panned if both audio outputs were connected. (If you set LR PHASE below 100% in non-binaural mode, this will result in phase cancellation every time the signals of both audio channels overlap.) Finally, connect only the left audio output to your mixer or audio interface.
