Dolby Pro Logic
Use this mode for films
recorded using Dolby Pro
Logic Surround. The surround
channels have a 20-ms delay.

Phantom
This mode creates surround
sound from stereo recordings.
The center channel is not
used and the surround chan-
nels have a 20-ms delay.

Simulated
This mode provides surround
sound with no delay for the
surround speakers. This is not
a Dolby mode.

3-Stereo Mode
Use this mode to play back
Pro Logic-encoded films when
you do not want the surround
channels to play.

Stereo
This mode plays a recording
in traditional two-channel
stereo.

The test tone is used to cali-
brate the volume settings of
the speakers. A static noise
will be heard cycling, in
order, from the front left,
center, right, and both sur-
round speakers.

Using the remote control,
adjust the Center and
Surround levels until the vol-
ume of all the speakers is the
same during the test.

Note: The test tone is used
to calibrate the performance
of the system. When listening
to an actual recording, the
volume level of the surround
channels is generally much
lower than that of the front
channels. In fact, when lis-
tening to a movie, virtually
all of the dialogue and a sub-
stantial amount of the effects
are reproduced through the
center channel.
