ENGLISH
Operation
To select a surround mode using the remote
control, press the button for the major surround
mode group that includes the mode you wish to
choose from: Dolby
M
, DTS Surround
N
,
DTS Neo:6
T
, Logic 7
O
, Stereo
S
or
DSP Surround
A
.The first press of the but-
ton will show the current mode from that group
if it is already in use, or the first available 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 Main Information Display
Ò
and the
on-screen display.
To select from the DSP modes (Hall 1, Hall 2,
Theater) press the Surround Mode Selector
A
repeatedly to scroll through the list of avail-
able modes.
As the surround modes change, a blue LED will
light next to the current mode in the Surround
Mode Indicators
(
list on the front panel.
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.
When the 6-Channel/8-Channel direct inputs are
in use there is no surround processing, as these
inputs take the analog output signals from an
optional, external DVD-Audio or SACD player, or
another source device and carry them straight
through to the volume control.
To listen to a program in traditional two-channel
stereo, using the front left and front right
speakers only (plus the subwoofer, if installed
and configured), press the Stereo Button
5
S
until SURROFF
appears in the Main
Information Display Ò.
Digital Audio Playback
Digital audio is a major advancement over older
analog surround processing systems such as
Dolby Pro Logic. It delivers five, six or seven
discrete channels: left front, center, right front,
left surround and right surround and with DTS
ES (see below) even surround back (with left and
right). Each channel reproduces full frequency
range (20Hz to 20kHz) and offers dramatically
improved dynamic range and significant
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 (originally known as AC-3
®
) is 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
inputs
RN*Ó
of the AVR.
No demodulator 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, 6.1 or 7.1 audio. Although
both DTS and Dolby Digital are digital, they use
different 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 play-
ers and DTS-DVDs on DVD players only. All that
is required is to connect the player’s digital out-
put to either the Optical or Coaxial input on
the rear panel
RN
or front panel
*Ó
.
In order to listen to DVDs encoded with DTS
sound tracks, the DVD player must be compati-
ble 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 out-
put 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 cir-
cuits in the AVR are capable of high quality digi-
tal-to-analog decoding, and they may be con-
nected 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).
Connections may be made to either the Optical
or Coaxial inputs
RN
on the rear panel or the
front panel Digital Inputs
*Ó
.
To listen to a PCM digital source, first select the
input for the desired source (e.g., CD) to feed its
video signal (if any) to the TV monitor and to
provide its analog audio signal for recording.
Next press the Digital Select button
Û
G
and then use the
⁄
/
¤
buttons
D
on the
remote, or the Selector buttons
7
on the front
panel, until the desired choice appears in the
Main Information Display
Ò
, then press the
Set button
@
F
to confirm the choice.
During PCM playback the unit automatically will
turn to the default surround mode or to the
LOGIC7 mode but you also may select any
surround mode except Dolby Digital or DTS.
Selecting a Digital Source
To utilize either digital mode you must have
properly connected a digital source to the AVR.
Connect the digital outputs from DVD players,
HDTV receivers, satellite systems or CD players
to the Optical or Coaxial inputs on the rear or
front panel
RN*Ó
. In order to provide a
backup signal and a source for analog stereo
recording, the analog outputs provided on digi-
tal source equipment should also be connected
to their appropriate inputs on the AVR rear panel
(e.g., connect the analog stereo audio output
from a DVD to the DVD Audio inputs
5
on
the rear panel when you connect the source’s
digital outputs).
To select a digital source such as DVD, first
select its input using the remote or front panel

as outlined in this man-
ual in order to feed its video signal (if any) to the
TV monitor and to provide its analog audio sig-
nal for recording.When the digital input associ-
ated with the input selected (e.g. “DVD”) is not
selected automatically (due to the input settings
made earlier during the system configuration,
see page 21), select the digital source by press-
ing the Digital Input Selector button
