A2DP is one profile of Bluetooth defined for 

in-car devices or AV devices that use wireless 

communication instead of a cable.

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 sends (plays) contents recorded in iTunes 

or on an iPhone/iPod touch/iPad to a compatible 

device via the network.

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 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® to provide well-balanced sound 

for every listener at any volume level.

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 MultEQ®

MultEQ® 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® 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.

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.

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.

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.

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. This delivers a thrilling 

surround sound experience in the home.

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 TrueHD is a high definition audio technology 

developed by Dolby Laboratories, using lossless 

coding technology to faithfully reproduce the sound 

of the studio master.

This format provides the facility to support up to 

8 audio channels with a sampling frequency of  

96 kHz/24 bit resolution and up to 6 audio channels 

with a sampling frequency of 192 kHz/24 bit 

resolution. Dolby TrueHD is adopted for applications 

that put very high importance on sound quality.

This function converts the number of channels of 

surround audio to a lower number of channels and 

plays back according to the system’s configuration.

This is an abbreviation of Digital Theater System, 

which is a digital audio system developed by DTS. 

DTS delivers a powerful and dynamic surround 

sound experience, and is found in the world’s finest 

movie theaters and screening rooms.

DTS 96/24 is a digital audio format enabling high 

sound quality playback in 5.1 channels with a 

sampling frequency of 96 kHz and 24 bit quantization 

on DVD-Video.

DTS Digital Surround is the standard digital surround 

format of DTS, Inc., compatible with a sampling 

frequency of 44.1 or 48 kHz and up to 5.1 channels 

of digital discrete surround sound.

DTS Express is an audio format supporting low bit 

rates (max. 5.1 channels, 24 to 256 kbps).

This audio technology provides higher sound quality 

and enhanced functionality than the conventional 

DTS and is adopted as an optional audio for Blu-ray 

Disc. This technology supports multi-channel, high 

data transfer speed, high sampling frequency, and 

lossless audio playback. Maximum 7.1-channels are 

supported in Blu-ray Disc.

DTS-HD High Resolution Audio is an improved 

version of the conventional DTS, DTS-ES and 

DTS 96/24 signals formats, compatible with 

sampling frequencies of 96 or 48 kHz and up to 

7.1 channels of discrete digital sound. High data 

bit rate performance provides high quality sound. 

This format is fully compatible with conventional 

products, including conventional DTS digital 

surround 5.1-channel data.

DTS-HD Master Audio is a lossless audio format 

created by Digital Theater System (DTS). This 

format provides the facility to support up to 8 audio 

channels with a sampling frequency of 96 kHz/ 

24 bit resolution and up to 6 audio channels with 

a sampling frequency of 192 kHz/24 bit resolution. 

It is fully compatible with conventional products, 

including conventional DTS digital surround 

5.1-channel data.

DTS NEO:6™ is a matrix decoding technology 

for achieving 6.1-channel surround playback 

with 2-channel sources. It includes “DTS NEO:6 

Cinema” suited for playing movies and “DTS 

NEO:6 Music” suited for playing music.

The difference between the maximum undistorted 

sound level and the minimum discernible level 

above the noise emitted by the device.
