Digital Cinema Auto Calibration
Digital Cinema Auto Calibration was developed
by Sony to automatically measure and adjusts
the speaker settings to your listening
environment in a short period of time.
Digital Direct Twin Drive Subwoofer
Utilizing Sony's proprietary S-Master
technology, the Digital Direct Twin Drive
Subwoofer features two S-Master Digital
Amplifiers that provide dedicated power to a
strategically located subwoofer for astounding
sound performance. Easy to set up, Digital
Direct Twin Drive Subwoofer provides a stable
sound field over a much larger listening area
without having to adjust frequency levels.
Digital Infrared Audio Transmission
Recent times have been witness to the rapid
spread of DVDs, Digital Broadcasting Satellite
Receiver and other high-quality media. In order
to ensure that the subtle nuances endowed by
these high-quality media would be transmitted
with no accompanying deterioration, Sony
developed a technology called “Digital Infrared
Audio Transmission” for the infrared
transmission of digital audio signals using no
compression, and it introduced it into the
system.
This technology transfers digital audio signals
using no compression inside the subcarrier
frequency band allocated by the IEC
(International Electronic Committee) and
JEITA (Japan Electronics and Information
Technology Industries Association) for hi-fi
audio transmission applications. (See Fig. 1)
Dolby Digital
This movie theater sound format is more
advanced than Dolby Surround Pro Logic. In
this format, the surround speakers output stereo
sound with an expanded frequency range, and a
subwoofer channel for deep bass is
independently provided. This format is also
called “5.1” with the subwoofer channel
designed as the 0.1 channel (since it functions
only when a deep bass effect is needed). All six
channels in this format are recorded separately
for superior channel separation. Furthermore,
since all the signals are processed digitally, less
signal degradation occurs.
Dolby Pro Logic II
Dolby Pro Logic II creates five full-bandwidth
output channels from 2 channel sources. This is
done using an advanced, high-purity matrix
surround decoder that extracts the spatial
properties of the original recording without
adding any new sounds or tonal colorations.
x Movie mode
The Movie mode is for use with stereo television
shows and all programs encoded in Dolby
Surround. The result is enhanced soundfield
directionality that approaches the quality of
discrete 5.1-channel sound.
x Music mode
The Music mode is for use with any stereo music
recordings, and provides a wide and deep sound
space.
Dolby Surround Pro Logic
As one method of decoding Dolby Surround,
Dolby Surround Pro Logic produces four
