Marantz SR5001 ユーザーズマニュアル

The SR4001/SR5001 is equipped with many 
surround modes. These are provided to reproduce 
a variety of surround sound effects, according to the 
content of the source to be played.
The available surround modes may be restricted 
depending on the input signal and speaker setup.

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 fl ag 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

x movie processing before play.

PCM 96 kHz source material can be played in this 
mode.

•  When you use this mode with certain DVD and CD 

players, performing operations such as “Skip” or 
“Stop” may momentarily interrupt the output.

•  When the signal is not decoded, the mode is changed 

to AUTO mode automatically. Refer to page 34 to 
confi rm the available decoding mode.

2 MODE

This mode is used with source materials encoded in 
Dolby Digital and Dolby Surround.

This mode is enabled when playing source materials 
encoded in Dolby Digital.
Playing multichannel encoded 6.1 or 7.1-channel 
Dolby Digital sources provides five main audio 
channels (left, center, right, surround left and surround 
right) and Low Frequency Effect channel.
Dolby Digital EX decoding is not available in this 
mode.

Dolby Pro Logic 

II

x brings the excitement of surround 

sound to any stereo mix, while making existing 
Dolby Surround mixes sound more like discrete 5.1 
channels Surround sound.
Dolby Pro Logic 

II

x has 3 modes. Please see below.

This mode provides 6.1 or 7.1 channel surround 
sound from Dolby Surround encoded stereo movie 
sound tracks.

This mode provides 6.1 or 7.1 channel surround 
sound from conventional stereo sources, analog or 
digital, such as CD, Tape, FM, TV, Stereo VCR, etc.

Game mode restores the impact low-frequency 
surround effects by routing them to the system’s 
subwoofer.

This mode emulated original Dolby Pro Logic 
decoding (3/1 surround) suit for Dolby Surround 
encoded stereo movie soundtracks.

• Pro Logic IIx mode will decode as Pro Logic II 

mode when the SURROUND BACK SPEAKER 
is set NONE in SPEAKER SETUP menu. (See 
SPEAKER SETUP, page 25)

•  Pro Logic IIx mode is available for a 2ch input signal 

which is encoded in Dolby Digital or PCM format.

• PCM-audio signals can be subjected to Pro Logic 

processing when the sampling frequency is 32 kHz, 
44.1 kHz or 48 kHz.

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.

In a movie theater, fi lm 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.
Dolby Digital EX is not available in the system without 
surround back speaker(s).

DTS-ES adds the surround back channel audio to 
the DTS 5.1-channel format to improve the acoustic 
positioning and makes acoustic image movement 
more natural with the 6.1-channel reproduction.
This receiver incorporates a DTS-ES decoder, which 
can handle DTS-ES Discrete-encoded and DTS-ES 
Matrix-encoded program sources from DVD, etc..
DTS-ES Discrete 6.1 features digital discrete 
recording of all channels including the surround back 
channel(s) and higher quality of audio reproduction.
DTS-ES is not available in the system without a 
surround back speaker.

This mode is for DTS encoded source materials such 
as LASER DISC, CD, and DVD. Neo:6 is for some 2 
channel sources.

 : 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. 

This mode decodes 2-channel signals into 6-
channel signals using high-accuracy digital matrix 
technology.
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.

•  Neo:6 mode is available to 2ch input signals which 

are encoded in Dolby Digital or PCM format.

• PCM-audio signals can be subjected to Pro Logic 

processing when the sampling frequency is 32 kHz, 
44.1 kHz or 48 kHz.

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.

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 fi lm, including broadcast, 
videotape and stereo recorded music.
Depending on source material, you can select 

 mode, 

 mode or 

 

mode.

This mode is suited for playing back Circle Surround-
encoded and non-encoded film and television 
soundtracks. Cinema Mode enables 6.1-channel 
surround playback of 2-channel sources such as 
Video Cassettes, TV broadcasts, streaming media 
and DVDs.

This mode is suited for playing back Circle 
Surround-encoded and non-encoded music. Music 
Mode decodes, music DVDs, radio and TV music 
broadcasts and CDs into enveloping 6.1-channel 
surround.
