Surround Modes - Marantz SR7000 User Manual

SURROUND MODES
The SR7000 incorporates digital signal processors (DSP) which can reproduce various surround effects you experience in concert halls and movie
theaters, etc. Nine Surround Modes, are provided to reproduce a variety of surround sound effects, according to the content of the source to be played.
Surroud mode
FEATURES
1. AUTO
When this mode is selected, the receiver determines whether the digital input signal is Dolby Digital, PCM-audio or DTS.
Note:
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
processing before play.
96 Khz source matiriai can be play back in this mode.
2. STEREO
This mode bypasses all surround processing.
Stereo program sources the left and right channels play normaly when PCM-audio or analog stereo is input.
With Dolby Digital and DTS sources, the 5.1 multi-channels are converted to two channel stereo, 96 Khz source matiriai can
be play back in stereo mode.
3. DOLBY
This mode is used with source materials encoded in Dolby Digital and Dolby Surround.
Dolby Pro Logic processing can be used on Dolby Surround encoded two channel source material (Dolby Digital two
channels, PCM-audio and Analog stereo). "Riis allows play of the four discrete channels (left, center, right and surround).
Note:
PCM-audio signals can be subjected to Pro Logic processing when the sampling frequency is 32 kHz, 44,1 kHz or 48 kHz.
When a signal in another format is input, output will be muled.
4. DTS
Cinema
Music
This mode is for DTS encoded source materials such as LASER DISC, CD, and DVD.
In the DTS Music mode, the LFE signal is reduced by 10 dB. With DTS music material, you should select the DTS Music
mode.
When playing DTS movie discs select DTS cinema mode for proper reproduction of the LFE channel. The DTS mode cannot
be used when an Analog input has been selected. When the signal in another digital format is input, output will be muted,
5. MOVIE
HALL
MATRIX
These modes provide surround effect processing from each input source material.
They will produce theater, concert halt and stadium like atmospheres. Select as your taste desires,
Note;
PCM-audio signals can be processed in this mode when sampling frequency is 32 kHz, 44,1 kHz or 48 kHz.
The 96 kHz sampling frequency mules output.
6. 5-STEREO 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. Addtionally. the center channel reproduces a mix of the right and left channel.
7. S-Direct ON In the source direct mode, the tone control circuite and bass management configuration are bypassed for full range
frequeancy responce and the purist audio reproduction.
96 Khz source matiriai can be play back in this mode.
Notes:
internal speaker size is setup to front L/R = Large. Center = Large, Surround L/R = Large and Subwoofer = yes automatically,
Tone controls are also defeated.
Caution for 96kHz PCM-audio signal:
This signal can be played when a DVD-player or DAT-player
connected to the SR7000 is capable of 96 kHz PCM output. For
details, refer to the player's operation manual.
The signal can be played when STEREO or AUTO has been selected
for the Surround mode.
Some DVD formatted discs featured copy protect. When use such
disc. 96 kHz PCM signal is not output from the DVD player. For
details, refer to the player's operation manual.
Caution for DTS signal;
This signal can be played when the connected DVD-player, laser¬
disc player or CD-player is capable of DTS-digitai output. For
details, refer to the player's operation manual.
Depending on the player used, DTS play may produce noise. If that
happens, set the Surround mode to DTS.
Playing a DTS-CD or DTS laser disc causes the player's analog
output terminal to output noise. Before playing DTS sources, be
sure to connect the player's digital output to the SR7(X)0's digital
input. Be careful when connecting the output of these players to
analog audio input.
Note that the SR7000 has the following restrictive functions built in
to reduce noise emission as much as possible.
If DTS is selected while in the Surround mode, digital input cannot
be switched to analog input. When the analog input function has
been selected, Surround mode cannot be switched to DTS.
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.
