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.
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.
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.
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.
