Plugging into the inserts jacks on the front panel breaks the signal from the rear panel XLRs
INPUT 2 & 3
These are balanced inputs on TRS jacks - see Fig 2.6.3
For ubalanced operation wire as described above for Input 1 inserts or use a mono jack plug.
INPUT 4,5 & 6
These are all unbalanced inputs which have RCA/phono connectors. These are wired with the centre pin as hot (signal +) and the sleeve as screen (signal ground).
TAPE RECORD
This is line level output of the selected input or inputs. Output level depends on the settings of the input TRIMs and on how many inputs are selected at the same time. If the input TRIMs are set up as described in the 'Description of Controls' sections then the level will be approximately 0dBu.
