DTS

The Digital Theater System Digital Surround (simply called DTS) is a multi-
channel digital signal format that can process higher data rates than with Dolby
Digital. Although both Dolby Digital and DTS are 5.1 channel media formats,
discs bearing the “DTS” symbol are thought to provide better sound quality
due to the lower audio compression required. It also offers a broader dynamic,
producing magnificent sound quality.

A DTS audio input can be configured relative to its format as follows

Stereo:

If the detected audio is of DTS format, you can default it to one

of the following settings – NEO:6 Cinema, NEO:6 Music or None.

Surround:

If the detected audio is of DTS Surround format, you can

default it to one of the following settings – NEO:6 Cinema, NEO:6 Music,
Stereo Downmix or None.

None:

If ‘None’ is selected, the DTS signal will be defaulted to the ‘Stereo’

or ‘Surround’ settings set forth at the ‘PCM’ option. See discussion below
about ‘PCM’.

NOTE

Please refer to the section ‘Listening Mode’ at the Main Menu discussions
for a description of Stereo Downmix and DTS Neo:6 surround modes.

PCM

PCM (Pulse Code Modulation) is the digital representation of a standard
audio signal converted with little or no compression. If ‘None’ is selected
for any of the Dolby or DTS settings, this ‘PCM’ section will default the audio
signal as follows

Stereo:

The detected stereo audio format will be configured into one

of the following options – Pro Logic, PLIIx Movie, PLIIx Music, NEO:6
Cinema, NEO:6 Music EARS, Enhanced Stereo or None.

Surround:

one of the following options –PLIIx Movie, PLIIx Music, NEO:6 Music,

the input can be defaulted – Pro Logic, PLIIx Movie, PLIIx Music, NEO: 6
Cinema, NEO: 6 Music, EARS, Enhanced Stereo, Analog Bypass and None.

All these Listening Modes for ‘Dolby Digital,’ DTS’ ‘PCM and ‘Analog’ can
be directly changed by pressing the ‘Listening Mode’ button on the front
panel or through the ‘Listening Mode’ option at the Main Menu window.

DOLBY SETUP

Under this menu, the Dolby Digital’s Dynamic Range Control can be
adjusted as well as the settings for Dolby Digital Pro Logic IIx Music.

Dyn Range Ctrl :

You can select the effective dynamic range

(subjective range from soft to loud) for playback of Dolby Digital
soundtracks. For fully cinematic effect, always select 100%, the default.
Settings of 75%, 50%, and 25% progressively reduce dynamic range,
making soft sounds comparatively louder while limiting the peak
loudness of loud ones.

The 25% setting will yield the least dynamic range and is best for late-
night sessions or other times when you wish to retain maximum dialog
intelligibility while minimizing overall volume levels.

Dolby Pro Logic IIx Music :

Please refer to the same description of

‘PLIIx Music’ under the ‘ADjUSTING LISTENING MODES’ segment of the
‘OPERATION - USING THE M15 HD - MAIN MENU’.

DTS SETUP

Under this menu, the Dynamic Range Control of DTS Digital Surround can
be adjusted as well as the settings for DTS Neo: 6 Music.

Dyn Range Ctrl :

This is the same configurable Dynamic Range Control

feature as described above at Dolby Setup, the only difference being
the soundtrack is now in DTS format.

DTS Neo: 6 Music :

Please refer to the same description of ‘NEO

6: Music’ under the ‘ADjUSTING LISTENING MODES’ segment of the
‘OPERATION - USING THE M15 HD - MAIN MENU’.
