Operation
just as it was recorded in real life (e.g. sound
being recorded from left rear side will be heard
from that side only, for more details see chart on
page 21).
When no rear speakers are in use, the Dolby 3
Stereo mode should be selected with all surround
recordings.
Note that when Dolby Digital 2.0 signals (e.g.
"D.D. 2.0" tracks from DVD), that are encoded
with Dolby Pro Logic information, are received
via any digital input, the Dolby Pro Logic II Movie
mode will be selected automatically (in addition
to the Dolby Digital mode) and will decode a full
range 5.1 channel surround sound even from
those recordings (see also "Dolby Digital" on
page 24).
To create wide, enveloping sound field environ-
ments and defined pans and flyovers with all
analog stereo recordings select the Dolby Pro
Logic II Music mode or Harman Kardon's exclu-
sive Logic 7 Music mode for a dramatic improve-
ment in comparison to the Dolby Pro Logic (I)
mode of former times.
NOTE: Once a program has been encoded with
matrix surround information, it retains the sur-
round information as long as the program is
broadcast in stereo. Thus, movies with surround
sound may be decoded via any of the analog sur-
round modes such as Dolby Pro Logic II or Logic 7,
when they are broadcast via conventional TV sta-
tions, cable, pay TV and satellite transmission. In
addition, a growing number of made-for-television
programs, sports broadcasts, radio dramas and
music CDs are also recorded in surround sound.
You may view a list of these programs at the Dolby
Laboratories Web site at www.dolby.com.
Even when a program is not listed as carrying
intentional surround information, you may find
that the Dolby Pro Logic II, Dolby 3 Stereo or Logic
7 modes often deliver enveloping surround pre-
sentations through the use of the natural surround
information present in all stereo recordings.
However, for stereo programs without any sur-
round information the Theater, Hall and 5CH
Stereo modes should be tried (effective particularly
with old "extreme" stereo recordings) and for
mono programs, we suggest that you try the
Theater or Hall modes. And when you use only
two front channel speakers you should select
Harman's patented VMAx mode, delivering a virtu-
ally three dimensional sound space with two
speakers only.
Surround modes are selected using either the
front panel controls or the remote. To select a
surround mode from the front panel, press the
Surround Mode Group Selector Button
to scroll through the list of available surround
groups (for example, any Dolby mode or Logic 7
mode). Next press the Surround Mode
22 OPERATION
Selector Button
to choose the specific
mode within the desired group (for example,
within the Dolby mode group the options are
Dolby Pro Logic, Dolby Pro Logic II Music, Dolby
Pro Logic II Movies and Dolbt 3 Stereo). To select
a surround mode using the remote, any of the
surround mode selector buttons
until the desired mode appears. As
you press the buttons, the Surround mode name
will appear in the Main Information Display
. As the surround mode changes, a blue LED
will light next to the current mode in the
Surround Mode Indicators list
front panel. Regard that any time a surround
mode is changed it remains associated with the
input just selected until another choice is made.
NOTE: The name of each Surround Mode will
scroll through the Main Information Display
while the modes are being selected. To avoid
exiting from the surround mode selection
process, be certain to push the
/
while a mode name is still visible.
Note that the Dolby Digital or DTS modes may
only be selected when a digital input is in use. In
addition, when a digital source is present, the
AVR will automatically select and switch to the
correct mode (Dolby Digital or DTS), regardless of
the mode that has been previously selected. For
more information on selecting digital sources, see
the following section of this manual.
To listen to a program in traditional two channel
stereo, using the front left and front right speak-
ers only (plus the subwoofer if installed and con-
figured), follow the instructions shown above for
using the remote until

Digital Audio Playback
Digital audio is a major advancement over older
analog matrix surround systems. It delivers five dis-
crete channels: left front, center, right front, left sur-
round 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 descibed as "5.1". 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 (originally known as AC-3
a standard part of DVD, and is available on
specially encoded LD discs and satellite broadcasts
and it is a part of the new high-definition television
(HDTV) system.
Note that an optional, external RF demodulator
is required to use the AVR 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
on the
inputs
is required for use with DVD players or DTS-
encoded laser discs.
DTS
DTS is another digital audio system that is capa-
ble of delivering 5.1 audio. Although both DTS
and Dolby Digital are digital, they use different
buttons
methods of encoding the signals, and thus they
require different decoding circuits to convert the
digital signals back to analog.
DTS-encoded sound tracks are available on select
DVD and LD discs, as well as on special audio-
only DTS CDs. You may use any LD, DVD or CD
player equipped with a digital output to play
DTS-encoded special audio-only CDs with the
AVR, but DTS-LDs can be played on LD players
and DTS-DVDs on DVD players only. All that is
required is to connect the player's output to
either the Optical or Coaxial input on the rear
panel
or front panel
In order to listen to DVDs encoded with DTS
appears in
sound tracks, the DVD player must be compatible
with the DTS signal as indicated by a DTS logo
.
on the player's front panel. Note that early DVD
players may not be able to play DTS- encoded
DVDs. This does not indicate a problem with the
AVR, 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 DVDs, consult the player's owner's manual.
Please note that some DVD players are shipped
with their output set for Dolby Digital only. To
insure that DTS data is being sent to the AVR,
please check the setup menu system on your
DVD player to make certain that DTS data output
is enabled.
PCM Audio Playback
PCM (Pulse Code Modulation) is the non- com-
pressed digital audio system used for compact
discs, Non-Dolby Digital/DTS Laserdiscs and some
special PCM encoded DVDs. The digital circuits in
the AVR are capable of high quality digital-to-
analog decoding, and they may be connected
directly to the digital audio output of your
CD/DVD or LD player (LD only for PCM or DTS
programs, for Dolby Digital laser discs an RF
adapter is needed, see "Dolby Digital" above).
