Design and specifications are subject to change without 
notice.
Deep Color
Video signals for which the color depth of 
signals passing through an HDMI jack have been 
raised. The number of colors that could be 
expressed by 1 pixel was 24 bits (16,777,216 
colors) with the current HDMI jack. However, 
the number of colors which can be expressed by 
1 pixel will be 36, etc., bits when the receiver 
corresponds to Deep Color. Since the gradation 
of the depth of a color can be expressed more 
finely with more bits, continuous color changes 
can be more smoothly expressed.
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.
DTS
Digital audio compression technology 
developed by Digital Theater Systems, Inc. This 
technology conforms to 5.1-channel surround. 
This format comprises of stereo rear channel and 
there is discrete subwoofer channel in this 
format. DTS provides the same 5.1 discrete 
channels of high quality digital audio. The good 
channel separation is realized due to the all 
channel data being recorded discretely and 
processed in digitally.
 Standby power consumption 0.3 W.
 Halogenated flame retardants are not used in the 
certain printed wiring boards.
 Over 85 % power efficiency of amplifier block is 
achieved with the full digital amplifier, S-Master.

HDMI
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.
PCM (Pulse Code Modulation)
A method of converting analog audio to digital 
audio for easy enjoyment of digital sound.
S-Force PRO Front Surround
Sony’s long-term involvement in surround 
technology (and the vast amounts of acoustic 
data accumulated as a result) has led to the 
development of all-new processing method and 
advanced DSP to handle this task effectively, 
which we call S-Force PRO Front Surround. 
Compared with previous front surround 
technologies, S-Force PRO Front Surround 
reproduces a more convincing sense of distance 
and space, resulting in a true surround sound 
experience without the need for rear speakers.
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.
x.v.Colour
“x.v.Colour” enables the more faithful 
reproduction of various colors such as the 
brilliant colors of flowers and the turquoise blue 
of the southern ocean.
