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 Image=5, the factor is zero and nothing is subtracted from the left and right channels. When Center Image=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.

Off: 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 forward or backward. The setting of “3” is the normal position. Change the setting to “2” or lower to move the sound space forward setting to “4” or higher to move the sound space backward.

If the stereo recording has excessive broadness or too strong 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 soundfield 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 for 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.

Front Effect (TX-SR700/700E only)

Some live recordings contain acoustic reverberation. When you play these sources, more reverberation will be applied by the DSP, creating too much reverb effects and the sound loses frame or presence. In this case, set this setting to “Off” so that no reverberation from the DSP will be applied to the sound output from the three front channels. With this setting, the sound source is played as it is without any further reverberation.

Front Effect is only enabled when the listening mode is Orchestra, Unplugged, Studio Mix, or TV Logic.

Surround Effect (TX-SR700/700E only)

You can choose from “Off,” “Middle,” or “High.”

This adjusts the reflected and residual noises from the surround left and right speakers and surround back speaker.

Surround Effect is only enabled when the listening mode is Orchestra, Unplugged, Studio Mix, or TV Logic.
