Marantz SR4001 ユーザーズマニュアル

This mode plays back monaural recordings from 
any source, including CDs, DVDs and TV and radio 
broadcasts in compelling 6.1-channel surround.

• CS II mode is available for 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 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.

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 
multichannels are converted to two channel stereo. 
96 kHz PCM source material can be played back in 
stereo mode.

In the Source Direct mode, the tone control circuit 
and bass management confi guration  are  bypassed 
for full-range frequency response and the purist 
audio reproduction.

• Speaker size is set to Front L/R = LARGE, Center = 

LARGE, Surround L/R = LARGE and Subwoofer 
= YES automatically. Tone controls, equalizer and 
additional processing are deactivated.

•  When you use this mode with certain DVD and CD 

players, performing operations such as skip or stop 
may momentarily interrupt the output.

The Pure Direct mode further reduces sources of 
noise in addition to effect of the Source Direct mode, 
by blocking output from the video jacks (VIDEO, 
S-VIDEO, COMPONENT VIDEO and HDMI) and 
turning the FL display off.

*  Connected DVD-player, laser-disc player or 

CD-player needs to support DTS-digital output. 
You may not be able to play some DTS source 
signals from certain CD players and LD players 
even if you connect the player to the SR4001/
SR5001 digitally. This is because the digital signal 
has been processed (such as the output level, 
sampling frequency, or frequency response) and 
the SR4001/SR5001 cannot recognize the signal 
as DTS data. 

*  Depending on the player used, DTS play may 

produce a short noise. This is not a malfunction. 

*  While signals from DTS-laser disc or CD are 

playing in another Surround mode, you cannot 
switch to digital input or from digital input to analog 
input by INPUT SETUP in SETUP MAIN MENU or 
the A/D button.

*  The outputs for the VCR 1 OUT, DSS/VCR 2 

OUT, TAPE OUT, and CD-R OUT output analog 
audio signals. Do not record from CDs or LDs that 
support DTS using these outputs. If you do, the 
DTS-encoded signal will be recorded as noise.

*  When playing Dolby Digital Surround EX-encoded 

software in 6.1 channels, it is required to set the 
EX/ES mode.

*  Note that some of Dolby Digital Surround 

EX-encoded software does not contain the 
identifi cation signal. In this case, set the EX/ES 
mode manually.

*  AUTO, PURE-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 SR4001/
SR5001 will be muted. 

*  Certain DVD player models inhibit digital output. 

For details, refer to the player’s operation manual.

*  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.

*  HDCD is effective only at the time of digital input.

*  AUTO, PURE DIRECT, and STEREO modes can 

be used when playing HDCD signals (such as 
from CD discs that contain HDCD). 

*  You may not be able to play some HDCD source 

signals from certain CD players if you connect 
the player to the SR4001/SR5001 digitally. This 
is because the digital signal has been processed 
(such as the output level, sampling frequency, or 
frequency response) and the SR4001/SR5001 
cannot recognize the signal as HDCD data.
