Optical
Using an optical fi ber cable for digital signal input/output from 
DVD, CD, etc., provides better sound quality for playback or 
recording compared to analog. Only possible with equipment 
that has an optical terminal.
PCM (Pulse Code Modulation)
This is one of the methods that enable analog 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 
(analog 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 the 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 
the 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 speakers.
Images recorded with x.v.Color or Deep Color 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.Color
This is a name of products compliant with ISO Standard for 
wider color space: “xvYCC”. This system supports x.v.Color.
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 Color
This system can reproduce greater color gradation (4096 steps) 
when connected to a compatible TV and recorder, etc.
You can enjoy exceptionally rich, natural-looking colors, with 
smooth, detailed gradation and minimal color 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 theaters. 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.
