CUSTOM VS PRESET
Allows comparison listening to the custom and factory-default ver-
sions of the selected listening mode. When PRESET is selected, the
listening mode is heard in its factory-default condition – as if all
parameters had been restored to their factory-default settings. No
parameter settings are affected when this option is selected. The lis-
tening mode will revert to its modified condition when the CUS-
TOM VS PRESET option is closed.
When CUSTOM is selected, the listening mode is heard in its cus-
tom condition – with all of its current parameter settings. The CUS-
TOM option is available even when no parameter settings have
been adjusted. However, the PRESET and CUSTOM options will
sound identical until adjustments are made.
To toggle between the factory-default and modified versions of
the selected listening mode:
1. Follow the CUSTOM VS PRESET menu path to open the CUS-
TOM VS PRESET drop-down menu.
2. When the CUSTOM VS PRESET drop-down menu opens, press
the Menu and arrows to toggle between the PRESET
(factory-default) and CUSTOM (customized) versions of the
selected listening mode.
3. When finished, press the Menu arrow to close the CUS-
TOM VS PRESET menu.
4. Press the Menu arrow to close the CUSTOM menu and
return to the listening mode menu.
DIMENSION FRONT, NEUTRAL, REAR
Controls the relative balance of the sound field, which can be useful
with certain recordings to achieve a more suitable balance among
all speakers. When set to FRONT, the sound field is balanced
toward the front of the listening space. When set to NEUTRAL, the
sound field is balanced at the center of the listening space. When
set to REAR, the sound field is balanced toward the rear of the lis-
tening space.
EFFECT LVL -12dB to +6dB
Adjusts the amount of effect applied to the listening mode.
ES DECODING AUTO, ON, OFF
Controls the DTS-ES decoding feature, which can be used to
extract a rear channel from DTS sources.
• When set to ON, DTS-ES decoding is engaged for all DTS(-ES)
sources.
• When set to OFF, DTS-ES decoding is not engaged for all
DTS(-ES) sources.
• When set to AUTO, DTS-ES decoding is engaged when a 5.1-
channel matrix-encoded or 6.1-channel discrete-encoded
DTS-ES source is detected. DTS-ES decoding is not engaged
when a 5.1-channel DTS source is detected.
DTS-ES listening modes are available when DTS-ES decoding is
engaged. DTS listening modes are available when DTS-ES decoding
is not engaged. DTS-ES decoding cannot be engaged unless both
side and rear speakers are present. See “Speaker Setup” on page 3-
24 for additional information.
