Explanation of terms
A
A2DP
A2DP is one profile of Bluetooth defined for
in-car devices or AV devices that use wireless
communication instead of a cable.
Adobe RGB color, Adobe YCC601 color
The color space defined by Adobe Systems Inc.
Because it is a wider color space than RGB, it can
produce more vivid and natural images.
AirPlay
AirPlay sends (plays) contents recorded in iTunes
or on an iPhone/iPod touch/iPad to a compatible
device via the network.
ALAC (Apple Lossless Audio Codec)
This is a codec for lossless audio compression
method developed by Apple Inc. This codec can
be played back on iTunes, iPod or iPhone. Data
compressed to approximately 60 – 70 % can be
decompressed to exactly the same original data.
App Store
App Store is a site that sells application software
for such devices as the iPhone or iPod Touch, and
is operated by Apple Inc.
Audyssey Dynamic EQ®
Dynamic EQ solves the problem of deteriorating
sound quality as volume is decreased by taking into
account human perception and room acoustics.
Audyssey Dynamic EQ® works in tandem with
Audyssey MultEQ® XT 32 to provide well-balanced
sound for every listener at any volume level.
Audyssey Dynamic Surround Expansion
(A-DSX)
Audyssey DSX® is a scalable system that adds
new speakers to improve surround impression.
Starting with a 5.1 system Audyssey DSX® first
adds Wide channels for the biggest impact on
envelopment. Research in human hearing has
proven that information from the Wide channels is
much more critical in the presentation of a realistic
soundstage than the Back Surround channels found
in traditional 7.1 systems. Audyssey DSX® then
creates a pair of Height channels to reproduce the
next most important acoustical and perceptual cues.
In addition to these new Wide and Height channels,
Audyssey DSX® applies Surround Envelopment
Processing to enhance the blend between the front
and surround channels.
Audyssey Dynamic Volume®
Dynamic Volume solves the problem of large
variations in volume level between television
programs, commercials, and between the soft
and loud passages of movies. Audyssey Dynamic
EQ® is integrated into Dynamic Volume so that as
the playback volume is adjusted automatically, the
perceived bass response, tonal balance, surround
impression, and dialog clarity remain the same.
Audyssey LFC™ (Low Frequency Containment)
Audyssey LFC™ solves the problem of low
frequency sounds disturbing people in neighboring
rooms or apartments. Audyssey researchers found
the range of frequencies that most readily penetrate
wood and cement construction typical of homes and
apartments and then created a technology to contain
them. Audyssey LFC™ dynamically monitors the
audio content and removes the low frequencies able
to pass through walls, floors and ceilings. Audyssey
LFC™ then applies psychoacoustic processing to
restore the perception of low bass for listeners in
the room. The result is great sound that no longer
disturbs the neighbors.
Audyssey MultEQ® XT 32
MultEQ® XT 32 is a room equalization solution
that calibrates any audio system so that it can
achieve optimum performance for every listener
in a large listening area. Based on several room
measurements, MultEQ® XT 32 calculates an
equalization solution that corrects for both time
and frequency response problems in the listening
area and also performs a fully automated surround
system setup.
Auto Lip Sync
If you connect the unit to a TV that supports the
Auto Lip Sync function, it can automatically correct
delay between the audio and video.
B
Bass Sync
Audio sources such as BD and DVD inherently have
time delay between the bass components of the
satellite channel and the LFE channel. This function
adjusts such a delay for reproducing (replaying)
richer bass sound during playback. This function
is by default set to 0 msec. Since the delay varies
according to the title, play back the audio source
and adjust to the most effective value for playback.
For some audio sources that are played back, this
function may have little effect.
Bluetooth
Bluetooth is a short-distance wireless communication
technology used for connecting handheld devices
several meters apart. This enables notebook
computers, PDA s, mobile phones, etc. to connect
without a cable for transmitting audio and data.
D
Deep Color
An imaging technology supported by HDMI. Unlike
RGB, which uses 8 bits (256 shades) per color, it can
use 10 bits (1024 shades), 12 bits (4096 shades), or
16 bits (65536 shades) to produce colors in higher
definition.
Both devices linked via HDMI must support Deep
Color.
DLNA
DLNA and DLNA CERTIFIED are trademarks and/
or service marks of Digital Living Network Alliance.
Some contents may not be compatible with other
DLNA CERTIFIED® products.
Dolby Digital
Dolby Digital is a multi-channel digital signal format
developed by Dolby Laboratories.
A total of 5.1 channels are played: 3 front channels
(“FL”, “FR” and “C”), 2 surround channels
(“SL” and “SR”) and the “LFE” channel for low
frequencies.
Because of this, there is no crosstalk between
channels and a realistic sound field with a “three-
dimensional” feeling (sense of distance, movement
and positioning) is achieved.
A realistic, powerful sense of presence is achieved
when playing movie sources in AV rooms as well.
Dolby Digital EX
Dolby Digital EX is a 6.1-channel surround format
proposed by Dolby Laboratories that allows users
to enjoy in their homes the “DOLBY DIGITAL
SURROUND EX” audio format jointly developed by
Dolby Laboratories and Lucas Films.
The 6.1 channels of sound, including surround back
channels, provide improved sound positioning and
expression of space.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal
format that is compatible with up to 7.1 channels
of discrete digital sound and also improves sound
quality thanks to extra data bit rate performance. It is
upwardly compatible with conventional Dolby Digital,
so it offers greater flexibility in response to the source
signal and the conditions of the playback device.
Dolby Pro Logic
g
Dolby Pro Logic g is a matrix decoding technology
developed by Dolby Laboratories.
Regular music such as that on CDs is encoded into
5 channels to achieve an excellent surround effect.
The surround channel signals are converted into
stereo and full band signals (with a frequency
response of 20 Hz to 20 kHz or greater) to create
a “three-dimensional” sound image offering a rich
sense of presence for all stereo sources.
Dolby Pro Logic
gx
Dolby Pro Logic gx is a further improved version of
the Dolby Pro Logic g matrix decoding technology.
Audio signals recorded in 2 channels are decoded
to achieve a natural sound with up to 7.1 channels.
There are three modes: “Music” suited for playing
music, “Movie” suited for playing movies, and
“Game” which is optimized for playing games.
Dolby Pro Logic
gz
Dolby Pro Logic gz introduces a new dimension to
Home Entertainment through the addition of a pair
of front height channels. Compatible with stereo,
5.1-channel and 7.1-channel content, Dolby Pro
Logic
gz provides enhanced spaciousness, depth
and dimension to movies, concert video and video
game playback while maintaining the full integrity
of the source mix.
Dolby Pro Logic
gz identifies and decodes spatial
cues that occur naturally in all content, directing
this information to the front height channels,
complementing the performance of left and right
surround sound speakers. Content that is encoded
with Dolby Pro Logic
gz height channel information
can be even more revealing, with perceptually
discrete height channel information bringing an
exciting new dimension to home entertainment.
Dolby Pro Logic
gz, with front height channels is also
an ideal alternative for households that cannot support
the placement of back surround speakers of a typical
7.1-channel system but may have bookshelf space
available to support the addition of height speakers.
