Hi all, got a 5.1 svs speaker package today, hooked everything up etc etc. Came to turn the 605 on and do the first time setup with the test microphone. All speakers get recognised perfectly except the centre speaker (which does give out sound) and it gives an 'error' message. I have no idea what to do (my first 5.1 with amp) and can't seem to find any threads on here about it, please tell me something is not wrong with my centre I have tried many times, and even moved the microphone closer to the centre. The manual doesn't say much about it except the sub may be too high or speaker broken.
