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.

Dolby Surround (Dolby Pro
Logic)
Audio processing technology developed by
Dolby Laboratories, Inc. Center and mono
surround information is matrixed into two
stereo channels. When reproduced, audio is
decoded and output in 4 channel surround
sound. This is the most common audio
processing method for DVD-video.
x
DTS Digital Surround
Digital audio encoding/decoding technology
for theaters developed by DTS, Inc. It
compresses audio less than Dolby Digital,
delivering a higher quality sound
reproduction.
x
HDMI (High-Definition
Multimedia Interface)
HDMI (High-Definition Multimedia
Interface) is an interface that supports both
video and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Contents Protection), a copy protection
technology that incorporates coding
technology for digital video signals.
x
L.F.E. (Low Frequency Effects)
Sound effects of low frequencies which are
output from a subwoofer in Dolby Digital or
DTS, etc. By adding a deep bass with a
frequency between 20 to 120 Hz, audio
becomes more powerful.

S-AIR (Sony Audio Interactive
Radio frequency)
Recent times have seen the rapid spread of
DVD media, Digital Broadcasting, and other
high quality media.
To ensure that the subtle nuances of these high
quality media are transmitted with no
deterioration, Sony has developed a
technology called “S-AIR” for the radio
transmission of digital audio signals with no
compression, and has incorporated this
technology into the EZW-RT10/EZW-T100.
This technology transfers digital audio signals
with no compression using the 2.4 GHz band
range of ISM band (Industrial, Scientific, and
Medical band), such as wireless LANs and
Bluetooth applications.

S-Master
S-Master is an all-digital amplifier technology
developed by Sony, which effectively
minimizes the occurrence of sound
fragmentation and jitter, delivering superb
dialog clarity and faithful reproduction of the
original sound. The compact amplifier section
supports a higher power efficiency and
improved thermal performance.

Sampling frequency
To convert analog audio to digital, analog data
should be quantified. This process is called
sampling, and the number of times per second
the analog data is quantified is called the
sampling frequency. A standard music CD
stores data quantified at 44,100 times per
second, which is expressed as a sampling
frequency of 44.1 kHz. Generally speaking, a
higher sampling frequency means better sound
quality.
