WMA (Windows Media Audio)
One of the compressed digital audio formats developed by Microsoft Corporation. With
psychoacoustic technologies, this compression method achieves a high compression rate.
Reportedly, it is capable of compressing data quantity by about 1/20 maintaining a certain level of
audio quality.

Glossary of audio information other than audio
decoding format
This is a glossary of the technical terms related to audio information used in this
manual.
Bi-amplification connection (Bi-amp)
A bi-amplification connection uses two amplifiers for a speaker. When you use the bi-amplification
connection, the unit drives the tweeter and woofer in a speaker with the discrete amplifiers. As a
consequence, the tweeter and woofer provide clear audio signal without the interference.
LFE (Low Frequency Effects) 0.1 channel
This channel reproduces low-frequency bass signals and has a frequency range from 20 Hz to
120 Hz. This channel is added to the channels for all bands with Dolby Digital or DTS to enhance
low frequency audio effects. This channel is labeled 0.1 because it is limited to only low frequency
audio.
Lip sync
Video output sometimes lags behind audio output due to the complexity of signal processing
caused by an increase in video signal capacity. Lip sync is a technique for automatically
correcting the timing lag between audio and video output.

Glossary of HDMI and video information

This is a glossary of the technical terms related to HDMI and video information used in
this manual.
Composite video signal
With the composite video signal system, color, brightness, and synchronization data signals are
combined and transmitted with a single cable.
Deep Color
Deep Color is a technology that HDMI specification supports. Deep Color increases the number of
available colors within the boundaries defined by the RGB or YCbCr color space. Conventional
color systems process the color using 8 bits. Deep Color processes the color with 10, 12, or 16
bits. This technology allows HDTVs and other displays to increase from millions of colors to
billions of colors and eliminate on-screen color banding for smooth tonal transitions and subtle
gradations between colors.
HDMI
HDMI (High-Definition Multimedia Interface) is the world-wide standard interface for digital audio/
video signal transmission. This interface transmits both digital audio and digital video signals
using a single cable without any loss. HDMI complies with HDCP (High-bandwidth Digital Content
Protection) and provides a secure audio/video interface. For further information on HDMI, visit the
HDMI website at "http://www.hdmi.org/".
x.v.Color
"x.v.Color" is a technology that the HDMI specification supports. It is a more extensive color
space than sRGB and allows the expression of colors that were not hitherto possible. While
remaining compatible with the color gamut of sRGB standards, "x.v.Color" expands the color
space, and thus can produce more vivid, natural images.

Glossary of Yamaha technologies

This is a glossary of the technical terms related to Yamaha technologies used in this
manual.
CINEMA DSP (Digital Sound Field Processor)
Since the surround sound systems were originally designed for use in movie theaters, their effect
is best experienced in a theater that has many speakers designed for acoustic effects. Since
home conditions (such as room size, wall material, and number of speakers) can differ so widely,
it is inevitable that there are differences in the sound that you hear. Based on a wealth of actually
measured data, CINEMA DSP, Yamaha's original DSP technology provides the audiovisual
experience of a movie theater in your own home.
Compressed Music Enhancer
The Compressed Music Enhancer feature compensates for missing harmonics in compression
music formats (such as MP3). As a result, this technology provides improved performance for the
overall sound system.
SILENT CINEMA
Yamaha has developed a natural, realistic sound effect DSP algorithm for headphones.
Parameters for headphones have been set for each sound program, so that accurate
representations of all the sound programs can be enjoyed on headphones.
Virtual CINEMA DSP
Virtual CINEMA DSP allows the system to virtually reproduce the sound field of the surround
speakers with front left and right speakers. Even if the surround speakers are not connected, the
unit creates the realistic sound field in a listening room.
YPAO (Yamaha Parametric room Acoustic Optimizer)
The Yamaha Parametric room Acoustic Optimizer (YPAO) function detects speaker connections,
measures the distances from them to your listening position(s), and then automatically optimizes
the speaker settings, such as volume balance and acoustic parameters, to suit your room.
