NOTE
• Depending on the sound source or listening condition, surround
effect may not be obtained even when the Dolby Digital surround
or Dolby Pro Logic is selected.
• The full Dolby Digital surround or Dolby Pro Logic effect cannot
be obtained when using software not recorded in the Dolby

the DSP surround system instead (see page 10).

- The Dolby Pro Logic system is automatically canceled.
- The Dolby Digital surround mode is automatically changed to
“2chSTEREO.”
• While headphones are plugged in:
- The Dolby Pro Logic cannot be turned on.
- The Dolby Digital surround mode cannot be changed.
• The Dolby Pro Logic system is automatically canceled and
cannot be turned on when the input signal is 96 kHz.
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 Digital surround (except
“2chSTEREO”) or Dolby Pro Logic mode
according to the current type and placement of
your speakers.
(See page 15.)
2 Press the MANUAL SELECT button on the remote
control and hold it down for about two seconds
until “L” of “L/R 0dB” starts to flash.
A noise signal is sent to each channel in turn as follows:
DOLBY D (PRO LOGIC) NORMAL or WIDE mode
PHANTOM mode
3 STEREO NORMAL or WIDE mode
* “L” or “R” flashes to indicate one of the front speakers from
which the noise signal is output.
