ADJUSTING SPEAKER LEVEL
BALANCE
The unit is equipped with a built-in test signal generator called a
noise sequencer for easy balance adjustment of all five channels.
The sequencer outputs a noise signal that "travels" from channel
to channel, enabling the simple adjustment of sound level to
achieve the same apparent loudness, at your listening position,
from each channel.
1 Select the Dolby Pro Logic mode according to
your current type and placement of the speakers.
(See page 18.)
2 Press the MANUAL SELECT button on the remote
control and hold it down for about two seconds
until "L" of "L/R OdB" starts to flash.
