Center Image
DTS Neo:6 derives a center channel from two-channel PCM and
analog sources.
In cinema mode, for Lt/Rt film soundtracks, sounds steered to the
center are subtracted from the left and right channels.
In music mode, the intent in the front channels is less one of
steering and more one of stabilizing the front image by augmenting
it with a center channel, while preserving the original perspective of
the stereo mix. Therefore the derived center is never fully subtracted
from the left and right channels.
Center Image is the factor controlling the amount of subtraction. It
varies between 0 and 5 in steps of 1 and the default value is 3.
When Center lmage=5, the factor is zero and nothing is subtracted
from the left and right channels. When Center lmage=0, the center
channel is subtracted from the left and right channels at half level
(-6 dB) for each channel. The signal level sent to the center channel
output is not affected by Center Image.
This control should be set based on room layout and personal
preferences. A setting of 5 allows the left and right channels to pass
through unaltered from the stereo mix. A setting of 0 gives more
center channel dominance, which is particularly desirable if
listeners are located well off-center. At any setting, the center
speaker anchors the image.
Center Image is only enabled when the listening mode is DTS
Neo;6 Music.
Pro Logic II Music Panorama (Panorama)
Use this setting to extend the front stereo image to include the
surround speakers for an exciting wraparound effect with side wall
imaging.
On: Select to turn on the PL II Music Panorama mode.
Oti: Select to turn off the PL II Music Panorama mode.
Panorama is only enabled when the listening mode is Dolby Pro
Logic II Music,
Pro Logic II Music Dimension (Dimension)
Use this setting to gradually adjust the soundfield forwai'd or
backward. The setting of “3” is the normal position. Change the
setting to “2” or lower to move the sound space forwai'd setting to
“4” or higher to move the sound space backward.
If the stereo recording has excessive bi'oadness or too sti'ong
surroundness, move the sound space forward to get the appropriate
sound balance. In contrast, if the stereo recording is somewhat felt
like monaural or has narrowness, move the sound space backward
to get more surroundness.
Dimension is only enabled when the listening mode is Dolby Pro
Logic II Music,
Pro Logic II Music Center Width (Center Width)
In Pro Logic II decoding, center signals are output from the center
speaker. When the center speaker is not used, the decoder will
divide the center signal equally to both the front left and right
speakers to create a “phantom” center sound image.
The Pro Logic II Music Center Width mode allows you to adjust from
where the center sound image is heard. Using this, you can have the
soundlield be heard from the center speaker only, from the front left
and right speakers only (as a phantom center sound image), or from
all three speakers (center, front left and right) in various level
combinations. For home use, applying some width to the center
signal will improve the level balance Ibi' the center and main
speakers, and effect the width of the center sound image, or “weight”
of the sound. Many sound recordings processed for stereo playback
will be reproduced better by proper control of this setting. The
recommended setting for Pro Logic II Music mode is “3.” This allows
you to easily distinguish the Pro Logic II Music mode from the Pro
Logic II Movie mode whose setting is automatically set to “0.”
Center Width is only enabled when the listening mode is Dolby Pro
Logic II Music.
LFE Level (TX-SR70I/701E only)
The level can be adjusted to either or between -10 and 0
decibels in I-decibel increments. For Dolby Digital and DTS input
source signals, the LFE level set here is used. A setting of 0 decibels
is recommended for optimum performance; however, if the source
Is recorded with the low frequency range too strong, lower this
setting as necessai'y.
Academy Filter (TX-SR70I/701E only)
Older monaural film mixes relied on high-frequency rolloff in
presentation to sound properly balanced, so that excessive hiss from
the grain structure of the film would not be heard. The high-
frequency loss was typically due to a combination of optical slit
loss, electrical tillers, loudspeaker response, and screen loss. Some
films have been transferred to video without such a high-frequency
rolloff, and thus sound overly bright and hissy.
The TX-SR701/701E/601/601E Includes this “Academy hlter,”
which is based on contemporary playback practices for such hims
over wide-range systems.
This can be set to either “On” or “Off.”
Input Channel
This allows you to set which input channel to use for monaural sound.
Auto L+R: Select this under normal circumstances. When the
input source is center channel, this center channel is used as the
monaural sound input channel. Otherwise, the left and right
channels are mixed and the mixed signal is used as the
monaural sound input channel.
Left/Right: You will need to select either left or right when
playing a video source that contains bilingual data. In such a case,
the left and right channels will contain the audio for different
languages. Select the channel with the language you desire.
Listening angle
The listening angle is the angle subtended by the front left and right
speakers as seen from the listener. The processing for the virtual
surround will be ba.sed on this angle. In the Theater-Dimensional
mode, the setting of 20 and 40 degrees are only for nominal
purposes, so select the setting that is closest to your actual listening
angle.

Center
In the Theater-Dimensional mode, if the speaker system has a
center speaker, the center channel signal can be output from the
center speaker. For in.stance, in systems where the front left and
right speakers ai'e small, use of the center speaker may provide a
better sound space and reduce the load on the front speaker. (For the
proper soundfield, it is important that the speaker levels and speaker
distances among the front right, front left, and center speakers are
matched. In order to ensure this, make sure that the settings in the
Speaker Distance Sub-menu and Level Calibration sub-menu are set
correctly.)
On: Select to have the center channel signal output to the center
speaker.
OfT: Select to have the center channel signal output to the front
left and right speakers (Phantom Center).
