Additional Information
• Whereas with conventional Dolby Pro Logic the surround
channel playback frequency band was limited, Dolby Pro Logic
II
offers a wider band range (20 Hz to 20 kHz or greater). In
addition, the surround channels were monaural (the surround
left and right channels were the same) with previous Dolby Pro
II
Logic, but with Dolby Pro Logic
signals.
• Various parameters can be set according to the type of source
and the contents, so it is possible to achieve optimum decoding
(

• Dolby Pro Logic
II
x furthers the matrix decoding technology of
Dolby Pro Logic
II
to decode audio signals recorded on two
channels into up to 7.1 playback channels, including the
surround back channel. Dolby Pro Logic
channel sources to be played in up to 7.1 channels.
The mode can be selected according to the source. The Music
mode is best suited for playing music, the Cinema mode for
playing movies, and the Game mode for playing games. The
Game mode can only be used with 2-channel audio sources.
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
Surround encoding technology.
• Dolby Surround is used for the sound tracks of movies recorded
on DVDs, LDs and video cassette tapes, as well as for stereo
broadcast signals from FM radio, TV, satellite broadcasts and
cable TV.
• Decoding these signals with Dolby Pro Logic
possible to achieve multi-channel surround playback. The
signals can also be played on ordinary stereo equipment, in
which case they provide normal stereo sound.
• There are two types of DVD Dolby surround recording signals.
q 2-channel PCM stereo signals
w 2-channel Dolby Digital signals
• When either of these signals is input to the AVR-2106, the
surround mode is automatically set to Dolby Pro Logic
the "DOLBY/DTS SURROUND" mode is selected.

[2] DTS Digital Surround
Digital Theater Surround (also called simply DTS) is a multi-
channel digital signal format developed by Digital Theater
Systems.
DTS offers the same "5.1" playback channels as Dolby Digital
they are played as stereo
(front left, front right, 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
operates with a relatively low compression rate. Because of this
the amount of data is great, and when DTS playback is used in
movie theaters, a separate CD-ROM synchronized with the film
is played.

x also allows 5.1-
With LDs and DVDs, there is of course no need for an extra disc;
the pictures 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.
There are also music CDs recorded in DTS. These CDs include
5.1-channel surround signals (compared to two channels on
current CDs). They do not include picture data, but they offer
surround playback on CD players that are equipped with digital
outputs (PCM type digital output required).
DTS surround 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 "hissing" noise from the CD
or LD player's analog outputs. If this noise is played with
the amplifier set at a very 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
holds true when playing CDs or LDs on a DVD player or
LD/DVD compatible player. For DVDs, the DTS signals are
recorded 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 undergo some sort of internal signal processing
(output level adjustment, sampling frequency conversion,
etc.). In this case the DTS-encoded signals may be
processed erroneously, in which case they cannot be
decoded by the AVR-2106, or may only produce noise.
Before playing 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 indicator on the AVR-2106
(
page 19) lights before turning up the master volume.
3: A DVD player with DTS-compatible digital output is required
to play DTS DVDs. A DTS Digital Output logo is featured on
the front panel of compatible DVD players. Recent DENON
DVD player models feature DTS-compatible digital output –
consult the player's owner's manual for information on
configuring the digital output for DTS playback of DTS-
encoded DVDs.
