FRONT SPEAKERS This procedure lets you adjust the sound output level balance between the front, center, and rear speakers using the built-in test tone generator. When this adjustment is performed, the sound output level heard at the listening position will be the same from each speaker. This is important for the best performance of the built-in Doiby Pro Logic surround decoder. The adjustment of each speaker output level should be done at your listening position with the remote control transmitter. Otherwise, the result may not be satisfactory. Before operation Set the CENTER MODE switch on the rear panel of the main unit to the position suitable for your speaker system configuration. (Refer to page 9 for details.) NORMAL (For 5 speaker configuration): Select this position when you use the center speaker. PHANTOM (For 4 speaker configuration): Select this position when you do not use the center speaker. The center sound will be output from the left and right front speakers.
