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.
