SURROUND MODES

The SR4200 incorporates digital signal processors (DSP) which can reproduce various surround effects you experience in concert halls and movie theaters, etc. These 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 ProLogicII
		processing before play.
		96 kHz source material can be playback in this mode and 96k will be shown in the display.
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 material can be
		playback in this mode and 96k will be shown in the display.
3.	2	This mode is used with source materials encoded in Dolby Digital and Dolby Surround.
		Dolby Pro Logic II 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 has below 3 modes.
	MOVIE	This mode provides 5.1 channel surround sound from Dolby Surround encoded stereo movie sound tracks.
	MUSIC	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	This mode emulated original Dolby Pro Logic decoding (3/1 surround) suit for Dolby Surround encoded stereo movie
		soundtracks.
		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.
4.	DTS	This mode is for DTS encoded source materials such as LASER DISC, CD, and DVD.
		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	These modes provide surround effect processing from each input source material.
	HALL	They will produce theater, concert hall and stadium like atmospheres. Select as your taste desires.
	MATRIX	Note:
	GAME	PCM-audio (32 kHz, 44.1 kHz or 48 kHz) and analog source material can playback in this mode.
6.	VIRTUAL	This mode create the virtual surround sound with the front right and left speakers.
		Note:
		PCM-audio (32 kHz, 44.1 kHz or 48 kHz) and analog source material can playback in this mode.
7.	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. Additionally, the center channel reproduces a mix of the right and left channel.
		Note:
		The 96 kHz sampling frequency mutes output.

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 the SR4200’s digital input. Be careful when connecting the output of these players to analog audio input.

Note that the SR4200 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 the SR4200 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.
