Marantz AV9000 manual Surround Modes

SURROUND MODES

The AV9000 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.

		FEATURES
1.	STEREO	This mode disables all surround processing.
		Left and right channels play as is when PCM-audio or analog stereo is input.
		Even when playing multi-channel encoded Dolby Digital and DTS sources, the multi-channels are mixed down to two
		channels, left and right, before being output.
2.	MONO	This mode is intended for use with old movies, televisions shows and other programs that have a monaural sound track. All
		sound will be reproduced through the center channel speaker, if installed. Even when playing multi-channel encoded Dolby
		Digital and DTS sources, the multi-channels are mixed down to monaural channel, center, before being output. If there is no
		center speaker, monaural sound is reproduced from the front left and right speakers. However output will be muted when 96
		kHz PCM signal is input.
3.	DOLBY	This mode is enabled when playing source materials encoded in Dolby Digital and Dolby Surround.
		Playing multi-channel encoded 5.1-channel Dolby Digital sources provides five main audio channels (left, center, right,
		surround left and surround right) and Low Frequency Effect channel.
		Dolby Pro Logic processing is performed on Dolby Surround encoded two channel signals (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.
		However output will be muted when 96 kHz PCM signal or DTS signal are input.
4.	DTS	This mode is valid only for DTS digital signal input and from DTS encoded source materials such as LASER DISC, CD, and DVD.
	(Cinema)	Playing 5.1-channel multi-channel encoded DTS sources provides five main audio channels (left, center, right, surround left
	(Music)	and surround right) and the Low Frequency Effect channel.
		On DTS Music mode, LFE signal is less than 10 dB. If you playback DTS music material, you should select the DTS Music.
		When a signal in another format is input, output will be muted.
		This mode cannot be used when Analog input has been selected.
5.	MOVIE	These modes provide surround effect processing in addition to Dolby Digital, DTS and Pro Logic decoding.
	HALL	They will produce theater-, concert-hall- and stadium-like atmospheres. Select as your taste requires.
	MATRIX	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.
6. 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.
		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.
7. AUTO		When this mode is selected, the program automatically switches playback mode according to type of digital input signal and
		then determines whether the digital input signal is Dolby Digital, PCM-audio or DTS to play the corresponding sound.
		When a Dolby Digital or DTS signal is input, the number of channels for which the corresponding signal is encoded will be
		played.
		Note:
		Inputting a Dolby Digital two channel signal with Dolby surround status automatically subjects that signal to Pro Logic
		processing before play.
		Inputting a PCM-audio signal plays stereo.

ENGLISH

Caution for DTS signal:

This signal can be played when the connected DVD-player, laser- disc player or CD-player responds to 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 this machine’s digital input. Be careful when connecting the output of these players to analog audio input.

Note that this machine has the following restrictive functions built in to reduce noise emission as much as possible.

If DTS is selected while in 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 96 kHz PCM-audio signal:

This signal can be played when a DVD-player or DAT-player connected to this machine responds to 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 are 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.
