SURROUND MODE
The SR7500 is equipped with many surround
modes. These are provided to reproduce a variety
of surround sound effects, according to the content
of the source to be played.
The available surround modes may be restricted
depending on the input signal and speaker setup.
AUTO
When this mode is selected, the receiver
determines whether the digital input signal is Dolby
Digital, Dolby Digital Surround EX, DTS, DTS-ES,
DTS 96/24 or PCM-audio.
Surround EX & DTS-ES will operate for multichannel
source that has a Dolby Digital Surround EX or DTS-
ES auto trigger flag in the digital signal.
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 IIx movie processing before
play.
PCM 96 kHz source material can be played in this
mode.
Notes:
• When you use this mode with certain DVD and
CD players, performing operations such as “Skip”
or “Stop” may momentarily interrupt the output.
• When the signal is not decoded, the mode is
changed to AUTO mode automatically. Refer to
page 24 to confirm the available decoding mode.
THX
THX 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 mode for all movies on disc, tape or
broadcast. In this mode, THX Surround EX will not
operate in this mode.
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.
THX Surround EX is not available in the system
without surround back speaker(s).
Note:
• When playing Dolby Digital Surround EX-
encoded software in 6.1 channels, it is required to
set the THX Surround EX mode.
