Maintenance
Unplug the AC power supply cord from the household AC outlet and wipe the system using a soft and dry cloth.
•  When the system is very dirty, wring the cloth soaked in water thoroughly, wipe the dirt and wipe moisture off with a dry cloth.
•  Do not use solvents such as benzine, thinner, alcohol, etc. because they may cause casing to deform and coating to come off.
•  Before using chemically treated cloth, read the instructions that come with the cloth carefully.

Glossary
Optical
Using 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 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.Color or Deep Color are also 
supported.
Surround signal
Audio signal made up with front speakers, center speaker and 
surround speakers. When the front speakers are only used for 
this system, surround signals are 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, when the front speakers are 
only used for this system, you can enjoy the sound fi  eld effect 
with Dolby Virtual Speaker as if you are listening to 5.1-channel 
sources.
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.
Analog
Audio signals produced from L/R audio output terminals of 
general equipment is called analog audio.
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 compatible TV and recorder, etc.
You can enjoy exceptionally rich, natural-looking colors, with 
smooth, detailed gradation and minimal color banding.
Digital
Blu-ray Disc players, DVD recorders, DVD players, and CD 
players are usually equipped with digital output terminals. 
Connect through the digital terminal to enjoy digital surround 
sounds such as Dolby Digital and DTS.
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.

Product Service/Listening caution
Selecting fi  ne audio equipment such as the unit you’ve just purchased 
is only the start of your musical enjoyment. Now it’s time to consider 
how you can maximize the fun and excitement your equipment offers. 
This manufacturer and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of your 
equipment by playing it at a safe level. One that lets the sound come 
through loud and clear without annoying blaring or distortion-and, most 
importantly, without affecting your sensitive hearing.
We recommend that you avoid prolonged exposure to excessive noise.
Sound can be deceiving. Over time your hearing “comfort level” adapts 
to higher volumes of sound. So what sounds “normal” can actually be 
loud and harmful to your hearing. 
Guard against this by setting your equipment at a safe level BEFORE 
your hearing adapts.
To establish a safe level:
Start your volume control at a low setting. 
Slowly increase the sound until you can hear it comfortably and 
clearly, and without distortion.
Once you have established a comfortable sound level: Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or 
loss in the future. After all, we want you listening for a lifetime. •
