for enjoying the exciting and powerful sound
of movie theaters at home. With this “Digital
Cinema Sound” developed by integrating a
DSP (Digital signal processor) and measured
data, the ideal sound field intended by
filmmakers can be experienced at home.
x Digital Concert Hall
“Digital Concert Hall” delivers richer sound
for 2ch stereo sources such as CDs, etc. With
the use of 5.1ch or 7.1ch speakers and virtual
speaker technology, stereoscopic
reverberation and reflected sound are
reproduced, and music software can be
enjoyed with richer sound and presence. The
sound field in a concert hall is recreated by a
geometrical analysis of the concert hall and
precise modeling of reflected and reverberant
sounds based on actual measured data. Tonal
qualities such as sound strength and frequency
response are taken into account and calculated
on the DSP (Digital Signal Processor) to bring
reverberation in. Sound is enjoyed with natural
and comfortable resonance, as if listening to
music in a concert hall.
x Pulse Height Volume
Pulse Height Volume, one feature of the S-
Master PRO technology. adjusts the sound
volume by controlling the pulse height. This
method loses no information and reproduces
higher quality sound than adjusting the sound
volume by digital processing.
x “S-Master”
This receiver is equipped with an “S-Master”
full digital amplifier - a unique digital
amplifier developed by Sony with the
following features.
1:Full digital processing
The signals are processed fully in digital, and
never go through the analog domain at any
time. As a result, the signal process is always
clean and accurate, and is not affected by noise
interference at signal paths which is often the
case with analog processing. In addition, S-
Master processing is both simple and high-
speed, thus providing high fidelity sound even
with vast information signals, like Super
Audio CDs.
2:Low heat emission
Another advantage to S-Master technology is
its low heat emission. The S-Master process
does not generate the same level of heat as
analog amplification does. This means that not
only is the S-Master more efficient, the sound
quality is not affected because there is no heat
to distort the final formation of the sound
waves.
