Lexicon
5-36
SURROUND DLY
0ms 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 that you 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 set to ON, THX Surround EX decoding is engaged for
all 5.1-channel Dolby Digital sources.
• When set to OFF, THX Surround EX decoding is not engaged
for all 5.1-channel Dolby Digital sources.
• When set to AUTO, 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 decod-
ing is not engaged when a non-flagged 5.1-channel Dolby
Digital source with or without THX Surround EX encoding is
detected.
• The MC-4 cannot automatically detect THX Surround EX
encoding in non-flagged 5.1-channel Dolby Digital sources. A
non-flagged source does not include information in the input
signal that identifies THX Surround EX encoding.
The THX SurEX listening mode is available when THX Surround
EX decoding is engaged. The THX and THX ULTRA2 listening
modes are available when THX Surround EX decoding is not
engaged. THX Surround EX decoding cannot be engaged unless
both side and rear speakers are present. See “SPEAKER SETUP” on
page 3-24 for more information.
SPEECH DETECT
ON, OFF
Distinguishes monaural speech from other input sources. When
set to ON, effects are lowered to minimize interference and
unnatural echo in monaural speech. When stereo input sources
are present, the front left and right channels are independently
used as inputs for ambience synthesis. When strong monaural
speech is present in the input source, the monaural component
of the ambience effect is reduced and the stereo component of
the effect is increased. When set to OFF, the amount of ambience
synthesis is dynamically controlled.
SUB LEVEL
OFF, –30dB to +12dB
Controls the output level of the audio output connector labeled
Subwoofer. The SUB LEVEL parameter appears on listening mode
menus when the listening mode does not accommodate multi-
channel output signals.
SUBWOOFER
OFF, –30dB to +12dB
Controls the output level of the audio output connector labeled
Subwoofer.
SURR ROLLOFF
500Hz to 20.0kHz, OFF
Applies high-frequency attenuation control to the audio output
connectors labeled Side L/R and Rear L/R. This filter is only
applied to output signals generated by the MC-4.
