INTRODUCTION
Thank you for purchasing the Marantz AV9000 THX/ DTS/Dolby Digital
Surround receiver. This remarkable component has been engineered
to provide you with many years of home theater enjoyment. Please take
a few minutes to read this manual thoroughly before you connect and
operate the AV9000. As there are a number of connection and
configuration options, you are encouraged to discuss your own
particular home theater setup with your Marantz A/V specialist dealer.
DESCRIPTION
DTS Technology was found in 1994 to commercialize 5.1 channels of
discrete digital audio into home theater systems. The DTS brings you
premiere quality and discrete multi-channel digital sound to movies.
The DTS playback unit is a motion picture sound system designed to
create full range digital sound reproduction using a theater's existing
audio system.
The no compromise DTS digital process sets the standard of quality
for cinema sound by delivering an exact copy of the studio master
recordings to neighborhood theaters. Now, every moviegoer can
hear the sound exactly as the moviemaker intended.
The Dolby Digital surround system lets you enjoy Digital TV, Digital
Satellite Receiver as well as DVD, LD software in digital surround,
which is the next step above Dolby Pro Logic. In comparison with
Dolby Pro Logic, Dolby Digital provides separate left surround and
right surround channels, for more precise localization of sounds and
a more convincing, realistic ambience. And, with Dolby Digital, all five
main channels are full ranges and a subwoofer can be added to each
channel ,if desired. By providing up to 5.1channels of digital audio
independently, Dolby Digital lets you enjoy better sound quality and
more powerful presence than conventional Dolby Surround.
THX is an exclusive set of standards and technologies established by
the world-renowned film production company, Lucasfilm Ltd. THX
resulted from George Lucas' desire to reproduce the movie
soundtrack as faithfully as possible both in the movie theater and in
the home theater.
THX engineers developed patented technologies to accurately
translate the sound from a movie theater environment into the home,
correcting the tonal and spatial errors that occur. When the THX
mode of the AV9000 is on, three distinct THX technologies are
automatically added:
Re-Equalization-restores the correct tonal balance for watching a
movie in a home environment. These sounds are otherwise mixed to
be brighter for a large movie theater. Re-EQ compensates for this and
prevents the soundtracks from being overly bright and harsh when
played in a home theater.
Timbre Matching-filters the information going to the surround
speakers so they more closely match the the tonal characteristics of
the sound coming from the front speakers. This ensures seamless
panning between the front and surround speakers.
Adaptive Decorrelation-slightly changes one surround channel's time
and phase relationship with respect to the other surround channel.
This expands the listening position and creates with only two
surround speakers the same spacious surround experience as in a
movie theater with multiple surround speakers.
The Marantz AV9000 was required to pass a rigorous series of quality
and performance tests, in addition to incorporating the technologies
explained above, in order to be THX Ultra certified by Lucasfilm Ltd.
THX Ultra requirements cover every aspect of performance including
pre-amplifier and power amplifier performance and operation, and
hundreds of other parameters in both the digital and analog domain.
Movies which have been encoded in Dolby Digital, DTS, Dolby Pro
Logic, stereo and Mono will all benefit from the THX mode when being
viewed. The THX mode should only be activated when watching
movies which were originally produced for a movie theater
environment. THX need not be activated for music, movies made
especially for TV, or shows such as sports programming, talk shows,
etc. This is because they were originally mixed for a small room
environment.
