Regular music such as that on CDs is encoded into 5-channels to
achieve an excellent surround effect.
The surround channel signals are converted into stereo and full band
signals (with a frequency response of 20 Hz to 20 kHz or greater) to
create a “three-dimensional” sound image offering a rich sense of
presence for all stereo sources.
Home THX Cinema Surround
THX is an exclusive set of standards and technologies established by
the world-renowned film production company, Lucasfilm Ltd. THX
grew from George Lucas’ personal desire to make your experience of
the film soundtrack, in both movie theaters and in your home theater,
as faithful as possible to what the director intended.
Movie soundtracks are mixed in special movie theaters called dubbing
stages and are designed to be played back in movie theaters with
similar equipment and conditions. The soundtrack created for movie
theaters is then transferred directly onto Laserdisc, VHS tape,
DVD, etc., and is not changed for playback in a small home theater
environment.
THX engineers developed patented technologies to accurately translate
the sound from the movie theater environment into the home, correcting
the tonal and spatial errors that occur. On the AVP-A1HDCI, when the
Home THX Cinema mode is on, THX post-processing is automatically
added after the Dolby Pro Logic, Dolby Digital or DTS decoder:
Re-EQ™ (Re-Equalization)
The tonal balance of a film soundtrack will be excessively bright and
harsh when played back over audio equipment in the home because
film soundtracks are designed to be played back in large movie
theaters using very different professional equipment. Re-Equalization
restores the correct tonal balance for listening to a movie soundtrack
in a normal home environment.
Dolby Headphone
This is a three-dimensional sound technology developed jointly by
Dolby Laboratories and Lake Technology Ltd. of Australia for achieving
surround sound using regular headphones.
Previously, when using headphones all the sounds resonated inside
the head and it was uncomfortable to listen with headphones for long
periods of time. Dolby Headphone simulates speaker playback in a
room and places the sound at the front or the sides, outside the head,
to achieve a powerful sound like the sound of movie or home theaters.
This technology is mainly for multichannel audio/video equipment with
Dolby Digital or Dolby Pro Logic Surround decoding functions and
works with a high performance digital signal processing (DSP) chip.
Dolby Headphone is effective not only for multichannel sources but
also for stereo programs.
On the AVP-A1HDCI, it is possible to output signals encoded in the
Dolby Headphone mode from the recording output terminal and record
them on a separate recorder.
