• Neo:6 offers a music mode to expand stereo  
nonmatrix recordings into the five- or six-  
channel layout, in a way which does not diminish  
the subtlety and integrity of the original stereo  
recording.  
DTS 96/24 offers the following:  
1. Sound quality transparent to the original 96/24  
master.  
INTRODUCTION  
Thank you for purchasing the Marantz SR6400  
DESCRIPTION  
2. Full backward compatibility with all existing  
decoders. (Existing decoders will output a 48  
kHz signal)  
Surround receiver.  
This remarkable component has been engineered  
to provide you with many years of home theater  
enjoyment. Please take a few minutes to read this  
manual thoroughly before you connect and  
operate the SR6400.  
As there are a number of connection and  
configuration options, you are encouraged to  
discuss your own particular home theater setup  
with your Marantz A/V specialist dealer.  
3. No new player required: DTS 96/24 can be  
carried on DVD-video, or in the video zone of  
DVD-audio, accessible to all DVD players.  
DTS was introduced in 1994 to provide 5.1  
channels of discrete digital audio into home theater  
systems.  
DTS brings you premium quality discrete  
multichannel digital sound to both movies and  
music.  
DTS is a multichannel sound system designed to  
create full range digital sound reproduction.  
The no compromise DTS digital process sets the  
standard of quality for cinema sound by delivering  
an exact copy of the studio master recordings to  
neighborhood and home theaters.  
4. 96/24 5.1-channel sound with full-quality full-  
motion video, for music programs and motion  
picture soundtracks on DVD-video.  
DTS-ES Extended Surround is a new multichannel  
digital signal format developed by Digital Theater  
Systems Inc. While offering high compatibility with  
the conventional DTS Digital Surround format,  
DTS-ES Extended Surround greatly improves the  
360-degree surround impression and space  
expression thanks to further expanded surround  
signals. This format has been used professionally  
in movie theaters since 1999.  
In addition to the 5.1 surround channels (FL, FR, C,  
SL, SR and LFE), DTS-ES Extended Surround  
also offers the SB (Surround Back) channel for  
surround playback with a total of 6.1 channels.  
DTS-ES Extended Surround includes two signal  
formats with different surround signal recording  
methods, as DTS-ES Discrete 6.1 and DTS-ES  
Matrix 6.1.  
PRECAUTIONS  
Now, every moviegoer can hear the sound exactly  
as the moviemaker intended.  
DTS can be enjoyed in the home for either movies  
or music on of DVD’s, LD’s, and CD’s.  
Dolby Digital identifies the use of Dolby Digital  
audio coding for such consumer formats as DVD  
and DTV. As with film sound, Dolby Digital can  
provide up to five full-range channels for left,  
center, and right screen channels, independent left  
and right surround channels, and a sixth ( ".1")  
channel for low-frequency effects.  
CAUTIONS ON INSTALLATION  
For heat dispersal, leave at least 20 cm/8 inch of  
space between the top, back and sides of this unit  
and the wall or other components.  
“DTS” and “DTS Digital Surround” are registered  
trademarks of Digital Theater Systems, Inc.  
• Do not obstruct the ventilation holes.  
Dolby Surround Pro Logic II is an improved matrix  
decoding technology that provides better spatiality  
and directionality on Dolby Surround program  
material; provides a convincing three-dimensional  
soundfield on conventional stereo music  
recordings; and is ideally suited to bring the  
surround experience to automotive sound. While  
conventional surround programming is fully  
compatible with Dolby Surround Pro Logic II  
decoders, soundtracks will be able to be encoded  
specifically to take full advantage of Pro Logic II  
playback, including separate left and right  
surround channels. (Such material is also  
compatible with conventional Pro Logic decoders.)

STANDBY  
But even in homes equipped for discrete  
multichannel, there remains a need for high-quality  
matrix decoding. This is because of the large  
library of matrix surround motion pictures available  
on disc and on VHS tape; and analog television  
broadcasts.  
The typical matrix decoder of today derives a  
center channel and a mono surround channel from  
two-channel matrix stereo material. It is better than  
a simple matrix in that it includes steering logic to  
improve separation, but because of its mono,  
band-limited surround it can be disappointing to  
users accustomed to discrete multichannel.

The stereo CD is a 16-bit medium with sampling at  
44.1 kHz. Professional audio has been 20- or 24-  
bit for some time, and there is increasing interest in  
higher sampling rates both for recording and for  
delivery into the home. Greater bit depths provide  
extended dynamic range. Higher sampling rates  
allow wider frequency response and the use of  
anti-alias and reconstruction filters with more  
favorable aural characteristics.  
20 cm (8 ins.)  
Dolby Digital EX creates six full-bandwidth output  
channels from 5.1-channel sources. This is done  
using a matrix decoder that derives three surround  
channels from the two in the original recording.  
For best results, Dolby Digital EX should be used  
with movies soundtracks recorded with Dolby  
Digital Surround EX.  
DTS 96/24 allows for 5.1channel sound tracks to  
be encoded at a rate of 96kHz/24bits on DVD-  
Video titles.  
Neo:6 offers several important improvements as  
follow,  
When DVD-video appeared, it became possible to  
deliver 24-bit, 96 kHz audio into the home, but only  
in two channels, and with serious limitations on  
picture. This capability has had little use.  
DVD-audio allows 96/24 in six channels, but a new  
player is needed, and only analog outputs are  
provided, necessitating the use of the D/A  
converters and analog electronics provided in the  
player.  
• Neo:6 provides up to six full-band channels of  
matrix decoding from stereo matrix material.  
Users with 6.1 and 5.1 systems will derive six  
and five separate channels, respectively,  
corresponding to the standard home-theater  
speaker layouts.

• Neo:6 technology allows various sound  
elements within a channel or channels to be  
steered separately, and in a way which follows  
naturally from the original presentation.

The new generation of Marantz Receivers is stylish  
and completely symmetrical. On the front panel of  
the SR6400, buttons are kept to a minimum. Source  
selectors and volume controls are intuitively placed.  
The large left dial knob on the left can be used as  
multi dial which allows all functions of the SR6400 to  
be operated via the front panel. The SR6400 is here  
to perform in your unrivaled home entertainment  
setup.  
FEATURES  
ACCESSORIES  
The SR6400 incorporates the latest generation of  
digital surround sound decoding technology such  
as Dolby Digital EX, Dolby Digital, DTS ES  
(Discrete 6.1 and Matrix 6.1), DTS Neo:6 (Cinema,  
Music), Dolby Pro-Logic II (Movie and Music),  
Circle Surround II (Cinema and Music) .  
In addition, Marantz has focused on the future. By  
utilizing pre-out jacks, 6.1 direct inputs and a  
RS232C communication port, the SR6400 is  
tomorrow's technology, today!  
Circle Surround II (CS-II) is a powerful and versatile  
multichannel technology. CS-II is designed to  
enable up to 6.1 multichannel surround sound  
playback from mono, stereo, CS encoded sources  
and other matrix encoded sources. In all cases the  
decoder extends it into 6 channels of surround  
audio and a LFE/subwoofer signal. The CS-II  
decoder creates a listening environment that  
places the listener “inside” music performances  
and dramatically improves both hi-fi audio  
conventional surround-encoded video material.  
CS-II provides composite stereo rear channels to  
greatly improve separation and image positioning –  
adding a heightened sense of realism to both audio  
and A/V productions.  
CS-II is packed with other useful feature like dialog  
clarity (SRS Dialog) for movies and cinema-like  
bass enrichment (TruBass). CS-II can enable the  
dialog to become clearer and more discernable in  
movies and it enables the bass frequencies  
contained in the original programming to more  
closely achieve low frequencies – overcoming the  
low frequency limitations of the speakers by full  
octave.  
Remote Controller RC7300SRa  
The TruSurround Headphone technology provides  
a surround sound listening experience over  
headphones.  
When listening to multichannel content such as  
DVD movies over headphones, the listening  
experience is fundamentally different than  
listening to speakers. Since the headphone  
speaker drivers are covering the pinna of the ear,  
the listening experience differs greatly from  
traditional speaker playback. TruSurround utilizes  
patented headphone perspective curves to solve  
this problem and provides a non-fatiguing,  
immersive, home theater listening experience.  
TruSurround Headphone also delivers exceptional  
3D audio from mono and stereo material.  
The SR6400 features a fully discrete 6 channel  
amplifier section capable of delivering 100 watts of  
high-current amplification, for continuously clean  
and stable power into each of the six channels. It  
employs a massive EI power transformer in  
combination with oversized filter capacitors. This  
design configuration is capable of a clear and  
powerful reproduction of the most demanding  
action movie soundtracks and full range  
(multichannel) music discs. Through its ability to  
generate very high output voltages, the SR6400  
can easily drive the most demanding speakers  
with optimum results.

The one marked UNSWITCHED is always live as  
long as the SR6400 is plugged into a live outlet.  
A component connected here may be left on  
permanently, or may be switched off with via its own  
power switch.  
These are the analog audio inputs and outputs. There  
are 7 audio inputs (4 of which are linked to video  
inputs) and 4 audio outputs (2 of which are linked to  
video outputs). The audio jacks are nominally labeled  
for cassette tape decks, compact disc players, DVD

Subwoofer  
The ideal surround speaker system for this unit is  
7-speaker systems, using front left and right  
speakers, a center speaker, surround left and right  
speakers, a surround back and a subwoofer.  
For best results we recommend that all front  
speakers be of the same type, with identical or  
similar driver units. This will deliver smooth pans  
across the front sound stage as the action moves  
from side to side.  
Your center channel speaker is very important as  
over 80 % of the dialog from a typical motion  
picture emanates from the center channel.  
It should possess similar sonic characteristics to  
the main speakers. Surround channel speakers  
need not be identical to the front channel speakers,  
but they should be of high quality.  
The surround center speaker is useful for playback  
of Dolby Digital Surround EX or DTS-ES. One of  
the benefits of both Dolby Digital and DTS is that  
surround channels are discrete full range, while  
they were frequency limited in earlier “Pro Logic’  
type systems.  
Bass effects are an important part of home theater.  
For optimal enjoyment a subwoofer should be used  
as it is optimized for low frequency reproduction. If  
you have full range front speakers, however, they  
may be used in place of a subwoofer with proper  
setting of the switches in the menu system.

You can control other Marantz products through  
this unit with the remote control by connecting the  
REMOTE CONTROL terminals on each unit.  
The signal transmitted from the remote control is  
received by the remote sensor on this unit. Then  
the signal is sent to the connected device through  
this terminal. Therefore you need to aim the  
remote signal only to the unit. Also, if a Marantz  
power amplifier (some models excluded) is  
connected to one of these terminals, the power  
amplifier’s, power switch is synchronized with this  
unit’s power switch.  
Whenever external infrared sensors or similar  
devices are connected to RC-5 IN of the SR6400,  
be sure to always disable operation of the infrared  
sensor on the main unit by using the following  
procedure.

other than the main unit to EXT.(EXTERNAL) for  
this feature.  
Note:  
Be sure to set to “IR=ENABLE” when external  
infrared sensors or similar devices are not  
connected. Otherwise, the main unit will be  
unable to receive remote control commands.  
5. To restore the original setting, perform steps 1  
to 4 to set to “IR=ENABLE”.

Use this parameter to specify the distance of each  
speaker’s position from the listening position. The  
delay time is automatically calculated according to  
these distances.  
Begin by determining the ideal or most commonly  
used seating position in the room.  
This is important for the timing of the acoustics to  
create the proper sound space that the SR6400  
and today’s sound systems are able to produce.  
Note : For speakers that you have selected “None”  
the Speaker Configuration sub-menu will not appear  
here. (There are several useful books and special

5 PL II (PRO LOGIC II) MUSIC  
PARAMETER  
Pro Logic II-Music mode creates a rich and enveloping  
surround ambience from stereo sources such as CDs.  
In this mode, SR6400 includes three controls to  
fine-tune the soundfield as follows.  
The tonal balance of a film soundtrack will be  
excessively bright and harsh when played back  
over audio equipment in the home. This is  
because film soundtracks were designed to be  
played back in large movie theater environments.  
Activating the HT-EQ feature when watching a  
film made for movie theaters corrects this and  
restores the correct tonal balance.  
The HT-EQ feature can be activated only while in  
Dolby Pro Logic Mode, or while decoding Dolby  
Digital or DTS encoded material.

This mode provides 5.1 channel surround sound  
from conventional stereo sources, analog or digital,  
such as CD, Tape, FM, TV, Stereo VCR, etc.  
Pro Logic  
When this mode is selected, the receiver determines  
whether the digital input signal is Dolby Digital,  
Dolby Digital Surround EX, DTS, DTS-ES, DTS 96/  
24 or PCM-audio.  
Surround EX & DTS-ES will operate for  
multichannel source that has a Dolby Digital  
Surround EX or DTS-ES auto trigger flag in the  
digital signal.  
When a Dolby Digital or DTS signal is input, the  
number of channels for which the corresponding  
signal is encoded will be played.  
Inputting a Dolby Digital two channel signal with  
Dolby surround status automatically subjects that  
signal to Pro Logic II movie processing before play.  
PCM 96 kHz source material can be played in this  
mode.  
To program the SR6400 for automatic standby,  
press tne SLEEP button on the remote.  
Each press of the button will increase the time

dts : This mode is enabled when playing source  
materials encoded in dts multichannel.  
Playing multichannel encoded 5.1-channel dts  
sources provides five main audio channels (left,  
center, right, surround left and surround right) and  
Low Frequency Effect channel.  
dts-ES decoding is not available in this mode.  
The DTS mode cannot be used when an analog  
input has been selected.  
EX/ES  
This mode provides 6.1 channel surround for  
DOLBY DIGITAL EX, DTS-ES encoded source  
material such as DVD.  
This mode cannot be used when an analog input  
has been selected.  
Notes:  
• When you use this mode with certain DVD and  
CD players, performing operations such as “Skip”

When the signal is not decoded, the mode is changed  
to AUTO mode automatically. Refer to page 22 to  
confirm the available decoding mode.  
Dolby Digital EX  
This mode decodes 2-channel signals into 6-  
channel signals using high-accuracy digital matrix  
technology.  
In a movie theater, film soundtracks that have been  
encoded with Dolby Digital surround EX technology  
are able to reproduce an extra channel which has  
been added during the mixing of the program.  
This channel, called Surround Back, places sounds  
behind the listener in addition to the currently  
available front left, front center, front right, surround  
right, surround left and subwoofer channels.  
This additional channel provides the opportunity  
for more detailed imaging behind the listener and  
brings more depth, spacious ambience and sound  
localization than ever before.  
NIGHT MODE  
The DTS NEO:6 decoder has near-discrete  
properties in the frequency characteristics of the  
channels as well as in channel separation.  
According to the signals to be played back, DTS  
NEO:6 uses either the NEO:6 CINEMA mode  
optimized for movie playback or the NEO:6 MUSIC  
mode optimized for music playback.

S (SOURCE ) - DIRECT  
NOTE for 96kHz PCM audio  
This mode is used to create a wider, deeper and more  
natural soundstage from two channel source material.  
This is done by feeding the left channel signal to  
both left front and left surround speaker and the  
right channel signal to both right front and right  
surround speaker. Additionally, the center channel  
reproduces a mix of the right and left channel.  
In the source direct mode, the tone control circuit  
and bass management configuration are bypassed  
for full range frequency response and the purist  
audio reproduction.  
96 kHz PCM source material can be played back in  
this mode.  
* AUTO, Source- DIRECT, and STEREO modes  
can be used when playing PCM signals with a  
sampling frequency of 96 kHz (such as from  
DVD-Video discs that contain 24 bit, 96 kHz  
audio). If such signals are input during playback  
in one of the other surround modes, output from  
SR6400 will be muted.  
Notes:  
*
Certain DVD player models inhibit digital output.  
For details, refer to the player’s operation manual.  
• Internal speaker size is setup to front L/R = Large,  
Center = Large, Surround L/R = Large and  
Subwoofer = Yes automatically. Tone controls  
and additional processing are also defeated.  
CIRCLE SURROUND II (CSII-CINEMA, CSII-MUSIC,  
CSII-MONO)  
*
Some DVD formatted discs feature copy protection.  
When using such disc, 96 kHz PCM signal is not  
output from the DVD player. For details, refer to the  
player's operation manual.  
Circle Surround is designed to enable multichannel  
surround sound playback of non-encoded and  
multichannel encoded material.  
Backward compatibility provides listeners with up to  
6.1 channels of surround performance from entire  
collection of music and film, including broadcast,  
videotape and stereo recorded music.  
• When you use this mode with certain DVD and CD  
players, performing operations such as “Skip” or  
“Stop” may momentarily interrupt the output.

* Depending on the player used, DTS play may  
produce a short noise. This is not a malfunction.  
This mode creates a virtualized surround sound  
experience from a two-speaker (front L and R)  
playback system playing any multichannel audio  
source (such as found on DVDs and digital  
broadcasts), including Dolby Digital, Dolby Pro Logic  
or DTS.  
* While signals from DTS-laser disc or CD are

This mode bypasses all surround processing.  
In stereo program sources, the left and right channels  
play normally when PCM-audio or analog stereo is  
input.  
With Dolby Digital and DTS sources, the 5.1

Press the EQ button on the remote to turn on the

The tonal balance of a film soundtrack will be  
excessively bright and harsh when played back  
over audio equipment in the home. This is because  
film soundtracks were designed to be played back  
in large movie theater environments.  
Activating the HT-EQ feature when watching a film  
made for movie theaters corrects this and restores  
the correct tonal balance.  
When 6.1 CH. INPUT is selected, the last video  
input used remains routed to the Monitor Outputs.  
This permits simultaneous viewing with video  
sources.  
Recording the video from one source and the  
audio from another  
You can add the sound from one source to the  
video of another source to make your own video

EDITING MACROS  
Macros may be edited using the following procedure.  
Characters displayed on the LCD include the  
following, depending on the function button for  
which the macro is being programmed:  
TV-M, DVD-M, VCR-M, DSS-M, TUN-M,  
CD-M, CDR-M, MD-M, TAP-M, AX1-M, AX2-  
M, AMP-M  
MACRO MODE  
• If, while programming, no buttons are  
pressed for approximately 1 minute, the

normal mode, and no macro will be  
programmed in the memory.  
PROGRAMMING MACROS  
1. Press and hold the T.MODE and MENU  
button until the MACRO are displayed on the  
LCD.  
Macros make it possible to use a single function  
button to perform more complex series of operations  
that would normally require pressing several  
buttons. A single button can be programmed to  
perform up to 10 steps in a sequence. A typical  
example of such a series might be as follows:  
• Turn the main amplifier power ON → Switch the  
function to DVD → Set the Surround Mode to  
Virtual → Set the DVD player to PLAY.  
• If a macro has already been set for the  
selected function button, the LCD will  
blink.  
• LEARN and MACRO is displayed blinking.  
CONFIRMING MACROS  
Macros may be confirmed using the following  
procedure.  
3. Press the buttons for the operations you wish  
to program as a macro in the sequence you  
want the macro to program them.

• Each of the function operations (12  
including CD, CD-R, etc.) can be used in a  
macro more than once, however for all  
except AMP, only the first function  
operation will be transmitted as a signal  
from the remote controller. Accordingly,  
within a single macro, it is not possible to  
switch between multiple function  
operations. (This is to prevent the  
switching of the receiver function  
operation.) Within a macro, the second  
time a function operation is used, it will  
only be used on the remote controller itself  
and no signal will be transmitted to the  
component.  
• The display will return to step 1.  
Press the DVD Function button. The LCD will
