Optical

Using optical ﬁ bre cable for digital signal input/output from DVD,

CD, etc., provides better sound quality for playback or recording

compared to analogue. Only possible with equipment that has

an optical terminal.

PCM (Pulse Code Modulation)

This is one of the methods that enable analogue sounds to be

converted to digital sounds without compression.

This method is used for music CD, etc.

Sampling frequency

Sampling is the process of converting the heights of sound wave

(analogue signal) samples taken at set periods into digits (digital

encoding). Sampling frequency is the number of samples taken

per second, so larger numbers mean faithful reproduction of the

original sound.

Standby through function

When this system and TV and Blu-ray Disc player/DVD recorder

etc. are connected with HDMI cables, image/audio from

Blu-ray Disc player/DVD recorder etc. can still be transmitted to

TV through this system even though the system is turned off.

This is useful when you want to enjoy late night viewing only

with the television’s speakers.

Images recorded with x.v.Colour, Deep Colour or 3D are also

supported.

Surround signal

Audio signal made up with front speakers, center speaker

and surround speakers. For this system, surround signal is

automatically played by Dolby Virtual Speaker.

WHISPER-MODE SURROUND

Even when the sound volume level is low, you can enjoy

dynamic surround playback similarly as during normal playback.

This is convenient when listening at night.

x.v.Colour

This is a name of products compliant with ISO Standard for

wider colour space: “xvYCC”. This system supports x.v.Colour.

1080p

This is one of the digital hi-vision images.

1080 is the number of effective scanning lines that constitute

the actual screen. This enables every detail to be beautifully

expressed. Images are less ﬂ ickered with progressive method

that scans in order from the top. This system supports 1080p.

5.1-channel surround

Monaural and stereo use one channel and two channels

respectively to reproduce sound, but 5.1-channel surround

uses 5 speakers and 1 subwoofer. The 5 channels are: 1 center

speaker, 2 front speakers, and 2 surround speakers at the

side of or to the rear of the sitting position. Sound output of the

subwoofer is much narrower than the other speakers, and so

is considered as 0.1. This is called 5.1-channel surround when

played through all 5.1 channels, and with this system you can

achieve a similar effect with Dolby Virtual Speaker.

7.1-channel virtual surround

When playing back 7.1-channel LPCM signals with this function,

you can enjoy wider sound ﬁ eld effects as if another speaker is

added.

ARC (Audio Return Channel)

This function was added to HDMI Ver.1.4.

This sends digital audio signals from the HDMI input terminal of

the TV, etc. to the HDMI output terminal of this system.

CPPM (Content Protection for Prerecorded Media)

This is the copyright protection technology which prevents ﬁ le

copy of DVD audio.

Decoder, Decode

Decoder is the device to enable us to hear audio data that is

encoded on DVD, etc., as a normal audio signal. This process

is called Decode.

Deep Colour

This system can reproduce greater colour gradation (4096

steps) when connected to compatible TV and recorder etc.

You can enjoy exceptionally rich, natural-looking colours, with

smooth, detailed gradation and minimal colour banding.

Dolby Digital

Digital sound compression technology developed by Dolby

Laboratories.

Compatible with surround sound as well as 2-channel stereo

sound. With this technology, you can keep massive amount of

audio data in a disc efﬁ ciently.

Dolby Pro Logic

This system can process not only Dolby Surround, but also

other 2-channel sources to produce a 5.1-channel sound for

a more realistic sound ﬁ eld. It is also possible to enhance old

movies recorded in stereo with this dynamic 5.1-channel sound.

This system uses Dolby Pro Logic to add surround effects to

stereo sources such as video cassettes and CDs.

Dolby Virtual Speaker

This system allows you to enjoy a surround effect with two

front speakers. This is not merely a “virtual surround” effect, but

rather uses the optimal speaker arrangements and listening

positions for 5.1-channel sound.

Down-sampling

This is the process of resampling by reducing the sampling rate

of a signal that was sampled at a certain rate.

DTS (Digital Theater Systems)

Surround system used in most movie theatres. Separation

works well between channels, resulting in realistic surround

effects.

Dynamic range

Dynamic range is the difference between the lowest level of

sound that can be heard above the noise of the equipment and

the highest level of sound before distortion occurs.

HDMI (High Deﬁ nition Multimedia Interface)

HDMI enables you to transmit digital audio and video signals

using a single cable.

You can also transmit control signals using HDMI connections.

Multi-channel LPCM (Linear PCM)

This is the uncompressed audio signal encoded digitally. Multi-

channel LPCM signals used for Blu-ray Disc, DVD audio, etc.

offer playback with higher-sound quality.

Up to 7.1-channel LPCM signals can be input to this system.
