SDP-40
5-41
SURR ROLLOFF 500Hz to 20.0kHz, OFF
Applies high-frequency attenuation control to the Main Zone audio
output connectors labeled Side L/R and Rear L/R. This filter is only
applied to output signals generated by the SDP-40.
SURROUND DLY 0 to 15ms
Increases the perceived depth of the listening space by delaying
the arrival time of signals from the side and rear speakers. It is
recommended to increase the setting when a greater sense of
depth is desired in the listening space.
SURROUND EX AUTO, ON, OFF
Controls the THX Surround EX decoding feature, which can be
used to extract a rear channel from 5.1-channel Dolby Digital
sources. When ON is selected, THX Surround EX decoding is
engaged for all 5.1-channel Dolby Digital sources. When OFF is
selected, THX Surround EX decoding is not engaged for all
5.1-channel Dolby Digital sources.
When AUTO is selected, THX Surround EX decoding is engaged
when a flagged 5.1-channel Dolby Digital source with THX
Surround EX encoding is detected. THX Surround EX decoding is
not engaged when a non-flagged 5.1-channel Dolby Digital source
with or without THX Surround EX encoding is detected.
Note:
The SDP-40 cannot automatically detect THX
Surround EX encoding in non-flagged 5.1-channel
Dolby Digital sources. A non-flagged input source
does not include information in the input signal that
identifies THX Surround EX encoding.
THX Surround EX listening modes are available when Dolby Digital
Surround EX decoding is engaged. THX or THX Ultra2 listening
modes are available when THX Surround EX decoding is not
engaged. Refer to the 5.1 ULTRA2, 5.1 SurEX, & 5.1
listening mode descriptions that begin on page 5-17, the
ULTRA2 & listening mode descriptions that begin on
page 5-24, or the 5.1a ULTRA2, 5.1a SurEX, & 5.1a
listening mode descriptions that begin on page 5-28 for more
information.
Note the following:
• The SURROUND EX parameter AUTO setting is not available for
the 5.1a THX listening modes.
•Toggling the SURROUND EX parameter setting produces low-
level clicks in the front speakers.
• THX Surround EX decoding cannot be engaged unless both
side and rear speakers are present.
• When the Shift command bank is activated, pressing the
remote control THX button while a 5.1-channel Dolby Digital
source is present activates the 5.1 ULTRA2, 5.1 SurEX,
or 5.1 listening mode. Subsequent presses adjust the
SURROUND EX parameter, cycling through the AUTO, ON,
and OFF settings.
• When the Shift command bank is activated, pressing the
remote control THX button while a 5.1-channel analog source
is present activates the 5.1a ULTRA2, 5.1a SurEX, or
5.1a listening mode. Subsequent presses toggle the
SURROUND EX parameter between the ON and OFF settings.
