Surround Modes - JBL Simply Cinema ESC 360 Simple Setup Manual

Surround Modes

Surround
Use this mode for films record-
ed using DTS, 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.
Test Tone
The Test Tone is used to
calibrate the volume settings
of each of the speakers in the
ESC 360. It is dependent on
the room where the system is
set up and the relative dis-
tances and positions of each
speaker to the listening posi-
tion. In all modes, a static-like
noise will be heard cycling, in
order: left front, center, right
front, right surround, left sur-
round, subwoofer. In modes
other than DTS or Dolby Digi-
tal, the sound from the two
surrounds will be coming at
the same time, since the sur-
rounds in
all available modes, except DTS
and Dolby Digital, are in
mono. When the Test Tone is
heard coming from a specific
channel, pressing the Adjust-
ment +/– (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 adjust-
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.
ment as the adjustment is
being made. The default
adjustment level of
0 dB is indicated by five sta-
tus-bar indicators illuminated.
If adjustments are done in a
mode where a certain channel
is not available, the adjust-
ment step for that channel is
skipped. For example, in Phan-
tom mode, the center-channel
level cannot be adjusted since
Phantom does not have a cen-
ter 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 adjust-
ed, do the test twice, once in
Dolby Digital or DTS (Dolby
-13-
Digital or DTS is automatically
selected when the ESC 360 is
connected to a DVD player
playing Dolby Digital-encoded
or DTS-encoded material) and
once again in Dolby Pro Logic.
Note: The Test Tone is used to
calibrate the system to repro-
duce all program materials at
the correct relative levels, as
was determined by the re-
cording engineers. When lis-
tening to actual surround-
encoded program material, the
volume level of the surround
channels is generally lower
than that of the front chan-
nels. In fact, virtually all of
the dialogue and a substantial
number of the effects in a
movie are reproduced through
the center channel.
