Windows standard audio file format, which defines the method of recording the digital data
obtained by converting audio signals. By default, the PCM method (no compression) is used, but
you can also use other compression methods.
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.

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
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 (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” 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.

SSID (Service Set Identifier) is a name that identifies a particular wireless LAN access point.
Wi-Fi (Wireless Fidelity) is a technology that allows an electronic device to exchange data or
connect to the Internet wirelessly using radio waves. Wi-Fi offers the advantage of eliminating the
complexity of making connections with LAN cables by using wireless connection. Only products
that complete Wi-Fi Alliance interoperability tests can carry the “Wi-Fi Certified” trademark.
WPS (Wi-Fi Protected Setup) is a standard established by the Wi-Fi Alliance, which allows easy
establishment of a wireless home network.

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.
The actually measured sound field data contain the information of the height of the sound images.
CINEMA DSP 3D mode achieves the reproduction of the accurate height of the sound images so
that it creates the accurate and intensive 3D sound fields in a listening room.
