3: Panorama Mode extends the front stereo

image to include the surround speakers for an

exciting “wrap around” effect with side wall

imaging.

PLII Music also applies a mild high-frequency shelf

filter to the surround channels for a more natural

soundfield. Auto-balance is disabled.

To change the PLII Music settings:

1: First enter the main menu by pressing on any

one of the menu buttons (< - > or SELECT)

2: Next move the cursor to “PLII”. Hit ‘SELECT’;

you are now in the ‘PLII Music’ menu.

Move the cursor to the setting you want to change.

The options are:

CEN – center width (0 to 7; default 3)

DIM – dimension (-3 to +3; default 0)

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 man-

agement 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-chan-

nel material. In cinema mode, for Left/Right film

soundtracks, sounds steered to the center are sub-

tracted 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 ste-

reo 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 chan-

nels. When Center Image = 0.5, the center chan-

nel 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 lay-

out and personal preferences. A setting of 0 allows

the left and right channels to pass through unal-

tered from the stereo mix. A setting of 0.5 gives

more center channel dominance, which is particu-

larly desirable if listeners are located well off-cen-

ter. At any setting, the center speaker anchors the

image.

To change the Center Image:

1: First enter the main menu by pressing on any

one of the menu buttons (< - > or SELECT)

2: Next move the cursor to “DTS”. Hit ‘SELECT’;

you are now in the ‘DTS Settings’ menu.

3: Move the cursor to ‘CEN’ and h0llit ‘SELECT’ –

you can now change the NEO:6 center imgage

setting. (0 – 0.5)

APPENDIX A

SP2 SURROUND MODES

Pressing the MODE button will illuminate the LED

and let you sequentially select one of the many

available decoding modes for 2 channel signals.

These special modes are designed to expand your

enjoyment of almost any 2 channel music source

and many other 2 channel signals. You are encour-

aged to experiment with the options on various

sources. Not all will supply something you may

like, but there are so many variables that it does

pay to take a few moments to listen to the options.

The custom SP2 Surround Modes use a set of DSP

algorithms to create a set of simulated signals

using the original left and right 2 channel data and

feeds these to the to centre and surround speak-
