Marantz SR-18EX manual Surround Modes

SURROUND MODES

The SR-19EX 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.

AUTO	When this mode is selected, the receiver determines whether the digital input signal is Dolby Digital, PCM-audio or DTS. THX
	Surround EX will operate for any 5.1 channel source that has a Dolby Digital Surround EX auto trigger flag in the digital signal.
	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.
	PCM 96 KHz source material can be played in this mode.
THX Cinema	THX Cinema surround mode applies additional processing to Dolby Digital, DTS, and Dolby Pro Logic multi-channel
	surround sources. The THX processing was developed by Lucasfilm Ltd. to recreated the sound of top-quality theater. Use
	the THX Cinema mode for all movies on disc, tape or broadcast. In this mode, THX Surround EX will not operate.
	Note:
	PCM-audio signals can be subjected to THX processing when the sampling frequency is 32 kHz, 44.1 kHz or 48 kHz.
	However output will be muted when 96 kHz PCM signal is input.
THX Surround EX 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.
	THX Surround EX will operate for any 5.1 channel source whenever THX is active. This mode is not available in the system
	without surround back speaker(s).

2(DOLBY Digital, This mode is used with source materials encoded in Dolby Digital and Dolby Surround.

DOLBY Pro Logic)	Dolby Pro Logic processing can be used on Dolby Surround encoded two channel source material (Dolby Digital two
	channels, PCM-audio and Analog stereo). This 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 muted.
DTS Cinema	This mode is for DTS encoded source materials such as LASER DISC, CD, and DVD.
DTS Music	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.
DSP SURROUND These modes provide surround effect processing from each input source material.
(Hall,Matrix,Movie)	They will produce theater, concert hall 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 mutes output.
5ch 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. Additionally, the center and surround back channel reproduces a mix of the right and left channel.
STEREO	This mode bypasses all surround processing.
MONO	Stereo program sources (left and right channels)play normally 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 material
	can be play back in stereo mode.
Source Direct	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 source material 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 DTS signal:

This signal can be played when the connected DVD-player, laser- disc player or CD-player is capable of DTS-digital 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 SR-19EX’s digital input. Be careful when connecting the output of these players to analog audio input.

Note that SR-19EX 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.

Caution for 96kHz PCM-audio signal:

This signal can be played when a DVD-player or DAT-player connected to SR-19EX 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 using such disc, 96 kHz PCM signal is not output from the DVD player. For details, refer to the player's operation manual.
