PAN – panorama (YES or NO; default NO)
Hit ‘SELECT’ – you can now change the chosen PLII setting.
Changing DTS NEO:6 Settings
Neo 6 provides up to six full-band channels of matrix decoding from stereo matrix material. Users with 6.1 and
5.1 systems will derive six and five separate channels respectively, corresponding to the standard home-theater
speaker layouts. (The “.1” subwoofer channel is generated by bass management in the preamp or receiver.)
Neo:6 also offers a music mode to expand stereo non-matrix recordings into the five- or six-channel layout, in a
way which does not diminish the subtlety and integrity of the original stereo recording.
“Center Image” is a variable in Neo:6 music mode only.
Neo:6 derives a center channel from two-channel material. In cinema mode, for Left/Right 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 0.5 in steps of 0.1
and the default value is 0.2.
When Center Image = 0, the factor is zero and nothing is subtracted from the left and right channels. When
Center Image = 0.5, 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 0 allows the left and
right channels to pass through unaltered from the stereo mix. A setting of 0.5 gives more center channel domi-
nance, which is particularly desirable if listeners are located well off-center. At any setting, the center speaker
anchors the image.
