grams bearing the logo of one of the major surround-
encoding processes such as Dolby Surround or DTS
Stereo may be played in either the Dolby Digital, Dolby
Pro Logic II Cinema,
DTS Neo:6 Cinema, or Logic 7
Cinema surround modes depending on the source
material.
NOTE: Once a program has been encoded with matrix
surround infor
mation, it retains the surround information
as long as the program is broadcast in stereo Thus
movies with surround sound may be decoded via any of
the analog surround modes such as Dolby Pro Logic II
Cinema, Logic 7 Cinema or DTS Neo:6 Cinema, when
they are broadcast via conventional cable
pay-TV and satellite transmission. In addition, a growing
number of made-for sports broad-
casts radio dramas and music CDs are also recorded in
surround sound.
Even when a program is not listed as carrying inten-
tional surround information, you may find that the Dolby
Pro Logic II, Logic 7 Enhanced or DTS Neo:6, VMAx

Digital
Digital audio is a major advancement over older analog
surround processing systems such as Dolby Pro Logic
It delivers five discrete channels: left front, center, right
front, left surround and right surround. Each channel
reproduces full frequency range (20Hz to 20kHz) and
offers dramatically improved dynamic range and signifi-
cant improvements to signal-to-noise ratios In addition,
digital systems have the capability to deliver an additional
channel that is specifically devoted to low-frequency
infor
mation.
This is the
“.1”
channel referred to when you
see these systems described as or
The bass channel is separate from the other channels
but since it is intentionally bandwidth-limited,
sound
designers have given it that unique designation.
Dolby Digital
Dolby Digital is a standard part of DVD
on specially encoded LD discs and satellite broadcasts
and it is a part of the high-definition television (HDTV)
system.
An optional, external RF demodulator is required to
use the
tracks available on laser discs Connect the RF output
of the LD player to the demodulator and then connect
the digital output of the demodulator to the
Optical or
Coaxial Inputs *(·c of the A No
demodulator is required for use with DVD players
or
DTS-encoded laser discs
DTS
DTS is another digital audio system that is capable of
delivering 5.1 or 6.1 discrete or matrix sound field
reproduction.
Although both DTS and Dolby Digital are
digital,
they use different methods of encoding the sig-
nals and thus they require different decoding circuits
to convert the digital signals back to analog
DTS-encoded soundtracks are available on select DVD
and LD discs as well as on special audio-only DTS
discs Y
with a digital output to play DTS-encoded discs with
the All that is required is to connect the
player’s output to either an
Optical or Coaxial Input
on the rear panel ·c or front panel *( .
In order to listen to DVDs encoded with DTS sound-
tracks the DVD player must be compatible with the
DTS signal as indicated by a DTS logo on the player’s
front panel. Early DVD players may not be able to play
DTS-encoded DVDs This does not indicate a problem
with the as some players cannot pass the
DTS signal through to the digital outputs If you are in
doubt as to the capability of your DVD player to handle
DTS discs consult the player’
IMPORTMany DVD players have a default
setting that does not pass through the DTS data, even
though the machine is capable of doing so If your
DVD player has the logo but does
not trigger DTS playback in the change the
player's settings in the or “Bitstream” configu-
ration menu so that DTS playback is enabled. The
method for doing this will vary with each player
some cases the proper menu choice will be
while in others it will be
manual for your player to find the specific infor
mation

Selecting a Digital Source
T you must have properly
connected a digital source to the 135. Connect
the digital outputs from DVD players
, HDTV receivers
satellite systems or CD players to the
Optical or
Coaxial Inputs *(·c. In order to provide a
backup signal and a source for analog stereo recording
the analog outputs provided on digital source equipment
should also be connected to their appropriate inputs on
the connect the analog stereo
audio output from a DVD to the
DVD Audio h
on the rear panel when you connect the source’s
digital outputs).
If you have not already configured an input for a digital
source using the on-screen menus as shown on page
16, first select the input using the remote or front-
panel controls as outlined in this manual.
