-13-
Surround
Use this mode for films recorded
using Dolby Digital or Dolby Pro
Logic Surround.
Phantom
This mode creates surround
sound from stereo recordings.
The center channel is not used
and the surround channels have
a 20-ms delay.
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.
Surround Modes
The Test Tone is used to
calibrate the volume settings of
each of the speakers in the
ESC333. It is dependent on the
room where the system is set up
and the relative distances and
positions of each speaker to the
listening position. In Dolby
Digital mode, a static-like noise
will be heard cycling, in order:
left front, center, right front,
right surround, left surround,
subwoofer. In modes other than
Dolby Digital, the sound from
the two surrounds will be
coming at the same time, since
the surrounds in all available
modes, except in Dolby Digital,
are in mono. When the Test
Tone is heard coming from a
specific channel, pressing the
Adjustment +/– (11) buttons
will increase or decrease the
level of sound coming from that
channel. The display status-bar
indicator (27) provides visual
indication of the adjustment as
the adjustment is being made.
The default adjustment level of
0 dB is indicated by five status-
bar indicators illuminated.
If adjustments are done in a
mode where a certain channel is
not available, the adjustment
step for that channel is skipped.
For example, in Phantom mode,
the center-channel level cannot
be adjusted since Phantom does
not have a center channel. In
stereo, neither the center nor
the surround levels can be
adjusted since Stereo does not
feature surround speakers or a
center speaker.
Using the remote control,
adjust each channel’s levels
until the volume of all the
speakers is the same during the
test. To make sure all channels
are properly adjusted, do the
test twice, once in Dolby Digital
(Dolby Digital is automatically
selected when the ESC333 is
connected to a DVD player’s
digital output, that specific
digital input is selected, and
the DVD player is playing Dolby
Digital-encoded material) and
once again in Dolby Pro Logic.
Note: The Test Tone is used to
calibrate the system to
reproduce all program materials
at the correct relative levels, as
was determined by the
recording engineers. When
listening to actual surround-
encoded program material, the
volume level of the surround
channels is generally lower than
that of the front channels. In
fact, virtually all of the dialogue
and a substantial number of the
effects in a movie are
reproduced through the center
channel.
