 This function is not available when the output method 
changes from the stand speaker to the TV speaker.
 We recommend that you set the maximum volume 
level to a little lower than the volume you usually 
listen to.
 Regardless of the maximum volume level you set, the 
VOLUME +/– button of the stand and the remote is 
operable.
 If you do not want to limit the maximum volume 
level, select “MAX.”
When you turn the TV off by using the POWER 
button on the TV’s remote, the stand and the 
connected components turns off automatically.

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.
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 is a more familiar term for the 
xvYCC standard proposed by Sony, and is a 
trademark of Sony. xvYCC is an international 
standard for color space in video.
This standard can express a wider color range 
than the currently used broadcast standard.
