(4) Stopping Playback
About the DVD standby function
When the ADV-M51 ’s function is set to DVD, the DVD
standby mode is set automatically if the disc remains in the
stop mode for approximately 10 minutes.
• In the DVD standby mode, the DVD section’ s power is
off and output of the video signals is also off.
The ADV-M51’ s display reads “DVD standby” at this
time.
• When in the DVD standby mode, the power of the
sections other than the DVD section is on and function
switching and other operations can be performed on the
main unit and remote control unit. When a DVD control
button (the play/pause and button open/close buttons on
the main unit, the play button on the remote control unit,
etc.) is operated, the DVD section ’s power turns on
automatically and disc playback and opening/closing of
the disc holder can be performed.
NOTE:
• The DVD standby function only turns off the power of the DVD
section. It is different from the DVD auto power off function set
with the system settings in Setup in that the DVD section
remains functional.

Dolby Surround
(1) Dolby DigitalDolby Digital is the multi-channel digital signal format developed by Do\
lby Laboratories. 
Dolby Digital consists of up to “5.1” channels - front left, front right, center, surround left, surround right, and an additional channel exclusively
reserved for additional deep bass sound effects (the Low Frequency Effe\
cts  – LFE – channel, also called the “.1” channel, containing bass
frequencies of up to 120 Hz). 
Unlike the analog Dolby Pro Logic format, Dolby Digital ’s main channels can all contain full range sound information, from the l\
owest bass, up
to the highest frequencies  – 22 kHz. The signals within each channel are distinct from the others, a\
llowing pinpoint sound imaging, and Dolby
Digital offers tremendous dynamic range from the most powerful sound eff\
ects to the quietest, softest sounds, free from noise and distortion.

(2) Dolby Pro Logic II
• Dolby Pro Logic II is a new multi-channel playback format developed by Dolby Laboratories u\
sing feedback logic steering technology and
offering improvements over conventional Dolby Pro Logic circuits.
• Dolby Pro Logic  IIcan be used to decode not only sources recorded in Dolby Surround ( ) but also regular stereo sources into five channels
(front left, front right, center, surround left and surround right) to achieve surround sound.
• Whereas with conventional Dolby Pro Logic the surround channel playback \
frequency band was limited, Dolby Pro Logic  IIoffers a wider
band range (20 Hz to 20 kHz or greater). In addition, the surround cha\
nnels were monaural (the surround left and right channels  were the
same) with previous Dolby Pro Logic, but Dolby Pro Logic  IIthey are played as stereo signals.
•
Various parameters can be set according to the type of source and the con\
tents, so it is possible to achieve optimum decoding (see page 59).
Sources recorded in Dolby Surround
These are sources in which three or more channels of surround have been \
recorded as two channels of signals using Dolby Surroun d
encoding technology.
Dolby Surround is used for the sound tracks of movies recorded on DVDs, \
LDs and video cassettes to be played on stereo VCRs, as well
as for the stereo broadcast signals of FM radio, TV, satellite broadcasts and cable TV.
Decoding these signals with Dolby Pro Logic makes it possible to achieve\
 multi-channel surround playback. The signals can also  be played
on ordinary stereo equipment, in which case they provide normal stereo s\
ound.
There are two types of DVD Dolby surround recording signals.

DTS Digital Surround
Digital Theater Surround (also called simply DTS) is a multi-channel d\
igital signal format developed by Digital Theater Systems .
DTS offers the same “5.1” playback channels as Dolby Digital (front left, front right and center, surround left and surround right) as well as the
stereo 2-channel mode. The signals for the different channels are fully \
independent, eliminating the risk of deterioration of sound quality due to
interference between signals, crosstalk, etc.
DTS features a relatively higher bit rate as compared to Dolby Digital (\
1234 kbps for CDs and LDs, 1536 kbps for DVDs) so it op erates with a
relatively low compression rate. Because of this the amount of data is g\
reat, and when DTS playback is used in movie theaters, a separate CD-
ROM synchronized with the film is played.
With LDs and DVDs, there is of course no need for an extra disc; the pic\
tures and sound can be recorded simultaneously on the same disc, so
the discs can be handled in the same way as discs with other formats.
Other media include CDs recorded in DTS. These are the same discs as con\
ventional CDs (recorded in 2 channels) but include 5.1  channel
surround signals. They do not include images, but they do permit surround playback on the ADV-M51 and on CD players.DTS surroun d track
playback offers the same intricate, grand sound as in a movie theater, right in your own listening room.

1 DTS signals are recorded in the same way on CDs and LDs as PCM signals. \
Because of this, the un-decoded DTS signals are output  as
random  “hissy” noise from the CD or LD player ’s analog outputs. If this noise is played with the amplifier set at a ve\
ry high volume, it
may possibly cause damage to the speakers. To avoid this, be sure to switch the input mode to  “AUTO” or “DTS” before playing CDs or
LDs recorded in DTS. Also, never switch the input mode to  “ANALOG” or “PCM” during playback. The same is true when playing CDs
and LDs recorded in DTS on the ADV-M51 or on LD/DVD compatible players. With DVDs, the DTS signals are rec\
orded with a special
recording method so there is no problem. For DVDs, the DTS signals are r\
ecorded in a special way so this problem does not occur .
2 The signals provided at the digital outputs of a CD or LD player may und\
ergo some sort of internal signal processing (output l evel
adjustment, sampling frequency conversion, etc.). In this case the DTS-\
encoded signals may be processed erroneously, in which case they
cannot be decoded by this unit, or may only produce noise. Before playin\
g DTS signals for the first time, turn down the master  volume to
a low level, start playing the DTS disc, then check whether the DTS indi\
cator on this unit (see page 45) lights before turning up the master
volume.
3 To play in DTS Digital Surround on the ADV-M51, set “DVD SETUP”  — “AUDIO SETUP”  — “DIGITAL OUT” to “Normal” in the setup.

Dolby Virtual Speaker
Dolby Virtual Speaker technology uses proprietary technology of Dolby Laborator\
ies to create a virtual surround sound field using only two
speakers for the front channels, allowing the user to experience sound a\

The virtual surround speakers are positioned at 105 °to the left and 105 °to the right.
BMulti-channel programs played according to the producer ’s intentions
The sound of the different channels is played in the position set upon m\
ixing. For example, sound set at the rear left is heard  from the rear
left.
BStereo programs played in surround
The Dolby Pro Logic  IIcircuit is used together with the Dolby Virtual Speaker circuitry to create a rich virtual surround sound field w\

Dolby Headphone
Dolby Headphone is a 3D sound technology developed jointly by Dolby Labo\
ratories and Lake Technology of Australia achieving surround sound
with regular headphones.
Normally when using headphones all the sounds are sounded in the head, m\
aking it uncomfortable to listen with headphones for long periods of
time. Dolby Headphone simulates speaker playback in a room and positions\
 the sound sources to the front or the sides, outside o f the head,
achieving a powerful sound similar to that of a movie theater or home th\
eater. This technology is aimed mainly at multi-channel audio or video
equipment including Dolby Digital or Dolby Pro Logic Surround decoding f\
unctions and operates inside a high performance digital signal processing
chip (DSP).
The Dolby Headphone mode can be used not only with multi-channel sources\
 but also with stereo programs.
