English Preparations and connections Speaker balance adjustment You can adjust the sound output level balance between the front, center, and rear speakers using the built-in test tone generator. This is important for the best performance of the built-in Dolby Pro Logic surround decoder. You can adjust the sound output level of center and rear speakers from -21 to +10 and the balance of the sound output levels of the left and right front speakers from L-6 to R-6. The adjustment of each speaker output level should be done from your listening position with the remote control. Otherwise, the result may not be satisfactory.
