Digital Audio Playback; Surround Mode Selection - Harman Kardon AVR 335 Owner's Manual

OPERATION
to confirm that no processing is being used. When
the headphone plug is removed, the audio feed to
the speakers will be restored.
• When the headphones are in use, you may take
advantage of the Dolby Headphone modes to bring
added spaciousness to headphone listening. Press
the Dolby Mode Select Button w or the
Surround Mode Group Selector 7 to cycle
through the three Dolby Headphone modes and
select the one that you prefer.

Surround Mode Selection

One of the most important features of the AVR 335
is its ability to reproduce a full multichannel surround
sound field from digital sources, analog matrix
surround-encoded programs and standard
stereo programs.
Selection of a surround mode is based on personal
taste, as well as the type of program source material
being used. For example, motion pictures or TV
programs 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 information, 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 Movie, Logic 7 Cinema or DTS Neo:6 Cinema, when
they are broadcast via conventional TV stations, cable,
pay-TV and satellite transmission. In addition, a growing
number of made-for-television programs, sports broad-
casts, radio dramas and music CDs are also recorded in
surround sound.
Even when a program is not listed as carrying intentional
surround information, you may find that the Dolby Pro
Logic II, Logic 7 Enhanced or DTS Neo:6, VMAx and
the Hall or Theater modes often deliver enveloping sur-
round presentations through the use of the natural infor-
mation present in all stereo recordings.
Surround modes may be changed at any time by
using either the front panel or remote control. To
select a new surround mode from the front panel, first
press the Surround Mode Group Selector Button
7 until the desired major surround mode group such
as Dolby, DTS or Logic 7 is selected. Next, press the
Surround Mode Selector Button 8 to choose the
specific individual surround mode.

The first press of the button will show the current mode
from that group if it is already in use, or the first avail-
able mode if you are currently using another mode. To
cycle through the available modes in that group, press
the button again until the desired mode appears in the
Lower Display Line ¯, in the on-screen display and
in the Surround Mode Indicators ˘.
As the surround modes change, the appropriate
˘
Surround Mode Indicator will light to indicate
which mode has been selected.
The Dolby Digital, Dolby Digital EX and DTS 5.1,
DTS-ES Matrix and DTS-ES Discrete modes may only
be selected when a digital input is in use. In addition,
when a digital source is present, the AVR 335 will
automatically select and switch to the correct mode,
regardless of the mode that has been previously
selected. For more information on selecting digital
sources, see the Digital Audio Playback section below.
The Dolby Pro Logic IIx modes are available only
when the AVR 335 has been configured for 6.1/7.1
operation by setting the Surround Back speakers as
either "Large" or "Small" as described on page 23.
These modes provide a matrixed 6.1-channel presen-
tation of analog sources. See page 29 for more infor-
mation.
When the 6-channel/8-channel direct inputs are in
use there is no surround processing, as these inputs 49 47 45 43
take the analog output signals from an optional, exter- 48 46 44 42
nal DVD-Audio or SACD player, or another source
35 37 39 41
device and carry them straight through to the volume

using the front left and front right speakers only (plus

the subwoofer, if installed and configured), press the

Group Selector 7 until the Stereo modes appear in
the on-screen display and Lower Display Line ¯.
Next, press the Surround Mode Select Button 8
until SURROUND OFF appears in the on-screen
display and Lower Display Line ¯.
The Surround Off mode provides an analog bypass of
the digital processing, including bass management.
Scroll until SURROUND OFF DSP appears if
you require bass management (usually used when the
system includes a separate subwoofer).

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
information. This is the ".1" channel referred to when you
see these systems described as "5.1, " "6.1" or "7.1. "
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, and is avail-
able on specially encoded LD discs and satellite broad-
casts and it is a part of the high-definition television
(HDTV) system.
An optional, external RF demodulator is required to
use the AVR 335 to listen to the Dolby Digital sound-
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 *(dg of the AVR 335. 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
41 51

to convert the digital signals back to analog.
36 40 46 50

39 49
DTS-encoded soundtracks are available on select DVD
34 44

and LD discs, as well as on special audio-only DTS
33 43
discs. You may use any LD or CD player equipped
32 42
with a digital output to play DTS-encoded discs with
31
the AVR 335. All that is required is to connect the
player's output to either an Optical or Coaxial Input
on the rear panel dg 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 AVR 335, 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's owner's manual.
