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.
1. STEREO
2. MONO
3. DOLBY
4. DTS
(Cinema)
(Music)
5. MOVIE
HALL
MATRIX
6. THX CINEMA
7. AUTO
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.
FEATURES
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.
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.
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.
This mode is valid only for DTS digital signal input and from DTS encoded source materials such as LASER DISC, CD, and DVD.
Playing 5.1-channel multi-channel encoded DTS sources provides five main audio channels (left, center, right, surround left
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.
These modes provide surround effect processing in addition to Dolby Digital, DTS and Pro Logic decoding.
They will produce theater-, concert-hall- and stadium-like atmospheres. Select as your taste requires.
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.
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.
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.
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.
