Movie Mode

The Movie mode is for use with VCRs, television shows, and all programs encoded

in Dolby Surround. The result is an enhanced soundfield that approaches the quality

of discrete 5.1-channel sound.

The Music mode is for use with any stereo music recordings, and provides a wide

and deep sound space. The Music mode includes controls that allow the sound to be

tailored to individual listening tastes.

• Center Width. This control allows center-channel sounds to be positioned

between the center speaker and the left/right speakers over a range of eight

steps. Step “3” uses a combination of all three front speakers to give the

best vocal imaging and most seamless soundstage presentation, and is

recommended for most recordings. Step “0” places all center sound in the

center speaker. Step “7” places all center sound equally in the left/right

speakers, just as in conventional stereo.

• Dimension. This control allows the user to gradually adjust the soundfield

either toward the front or the rear. This can be useful to help achieve the

desired balance from all the speakers with certain recordings that may

contain either too much or too little spatial effect. Step “3” is the

recommended setting, which has no effect on the sound. Steps “4” through

“6” gradually move the sound forward, and steps “2” through “0” move the

sound toward the surrounds.

• Panorama. This control extends the front stereo image to include the

surround speakers for an exciting “wraparound” effect with side-wall

imaging. It is particularly effective for recordings that have strong left- or

right-channel elements in the mix, since these are detected and accentuated

by the Panorama process.

All three of the above controls may be used alone or in any combination. After

experimenting with them on a few programs, it is easy to understand their effect and

which settings are preferable.

Dolby Digital EX creates six full-bandwidth output channels from 5.1 channel

sources by adding a rear center channel. This is done using a matrix decoder that

derives three surround channels from the two in the original recording. The center

rear is matrixed into the rear 2-channels of the 5.1 soundtrack, like what Pro Logic

does with the front three channels in the Pro Logic mode. The decoder takes the right

rear and left rear information, which also contains the center rear information, and

extracts the information so that the center rear channel is active. Thus, sound will be

heard out of the center rear speaker as well as the right rear and left rear speakers.

For best results, Dolby Digital EX should be used with movie soundtracks recorded

with Dolby Digital Surround EX.

DTS 5.1 is a multi-channel digital signal format developed by Digital Theater

Systems, Inc., that provides channels for the front left, right, and center, surround left

and right, and LFE. The process used by DTS produces audio tracks that closely

match the original master recording, with very little data compression.
