DOLBY 3 STEREO : Choose this setting to play back
movies and music (especially Laser Discs, video cassettes
and TV broadcasts with DOLBY SURROUND sound) when
not using the rear speakers. You get a clear perception of
the position and direction of the sound. DOLBY 3 STEREO
combines the front and rear signals so that you can enjoy a
regenerated sound field which has comparatively more lively
presence and a more expansive feeling from the three front
channels (front left, front right and center speakers) than
that of ordinary stereo regeneration.
ꢁUse the CENTER LEVEL buttons to adjust the center

– CENTER 0 dB lights up on the display.
– The level will be indicated on the display : MIN, –15, …

DOLBY 3 STEREO
ꢁPress the DOLBY 3 STEREO or use the SURROUND

CENTER MODE : In Dolby 3 Stereo mode, you can only
select NORMAL and WIDE.
THEATER : Use this when watching movie sources that
have a stereo soundtrack to enjoy the effect of being in a
movie theater.
CENTER LEVEL : use the CENTER LEVEL buttons to
adjust the center level as described above.
REAR LEVEL : adjusting the rear level is not available in
Dolby 3 Stereo mode.
DELAY TIME : adjusting the delay time of the rear
channel is not available in Dolby 3 Stereo mode.
HALL : Hall mode works best for recorded concerts and
other music programs. In this mode, the front speakers
provide a normal stereo effect while the rear speakers
provide a reverberated sound. This reverberation helps to
simulate the sound you might hear at a live concert.
THEATER, HALL, STADIUM
ꢁPress the THEATER, HALL, STADIUM respectively or
use the SURROUND MODE button on the remote control.
ꢁCENTER MODE and CENTER LEVEL are not available

ꢁUse the REAR LEVEL buttons to adjust the rear level as
described above.
ꢁUse the DELAY TIME button on the remote control to
adjust the delay time of the rear channel as described
above.
STADIUM : The "stadium" effect creates efficient,
reverberated sounds in order to obtain an expansive sound
field. For music sources like a rock concert, you will feel as if
you were actually at the live concert and seated very close
to the stage. For sports programs, such as a baseball game,
you can enjoy a powerful sound, thus obtaining the true
stadium effect.
OFF : Turns off the center and rear speakers for normal
stereo operation.
– The delay time is changed to 08,16, … , 96 milli seconds.
TEST TONE
Note : Dolby Pro Logic, Dolby 3 Stereo, Theater, Hall and

graphic equalizer. Please refer to your equalizer operating
instructions for guidance on switching off (or defeating) the
