B
Bass
15 Glossary
The lowest three octaves of the audio band.
Low bass is the bottom octave (20-40Hz), mid-
bass is the middle octave (40-80Hz), and upper
bass is the 80-160Hz octave.
A
AAC (Advanced Audio Coding)
An audio compression scheme defined as part
of the MPEG-ꢀ standard (also known as MPEG-
2 AAC or MPEG-2 NBC, or Not Backwards
Compatible). It offers better sound and a
compression ratio that is superior by roughly 30
percent compared to the MPEG-1 MP3 format.
Bit / bits
A bit is a binary digit, taking a value of either 0
or 1. For example, the number 10010111 is 8
bits long.
Bit rate
Bit rate is the number of bits that are conveyed
or processed per unit of time.The bit rate is
usually measured in some multiple of bits per
second (kilobits per second: kbps).The term
bit rate is a synonym for data transfer rate (or
simply data rate).
AC (alternating current)
An alternating current is an electrical current
whose magnitude and direction vary cyclically,
as opposed to DC (direct current), whose
direction remains constant.The usual waveform
of an AC power circuit is a sine wave, as this
results in the most efficient transmission of
energy. However certain applications use
different waveforms, such as triangular or square
waves.
Bluetooth
A short-range wireless protocol that is meant
to allow mobile devices to share information
and applications without the worry of cables or
interface incompatibilities.The name refers to a
Viking King who unified Denmark. Operates at
ꢀ.4 GHz. For more information, see bluetooth.
com.
Amplifier
A device, either a single stage or a large scale
circuit with multiple stages for creating gain, i.e.
it makes small signals larger.
Antenna
C
A device, such as a rod or wire, which picks up
a received radio frequency signal or radiates a
transmitted RF signal.
CBR (constant bit rate)
With CBR the encoder spends the same
amount of bits on each frame, regardless of
how much it may really need. Disadvantage
of CBR: Bits are wasted in case of absolute
blackness of a picture or complete silence in an
audio frame.And pictures or audio frames with
a lot of elements may need those bits.
Audio output
High-level (speaker) or line-level (RCA) signals
sent from one system component to another;
or the high-level signal from an amplifier to the
system speakers.
AUX
CD (Compact Disc)
Auxiliary input that allows you to connect
portable audio devices.
Format developed by Phillips, Sony, and Pioneer
for conveying music and data. CDs record
information by deforming the inner metal foil
on the disc with tiny micro pits burned in by a
laser.

CDDB
Digital
A centralized database of CDs, CD tracks, and
artists on the Web, now known as Gracenote.
The audio player or burner program can log on
to CDDB. It uploads the ID of the CD being
played, and then downloads the title, artist, and
track list.
A method to encode information using a binary
code of 0s and 1s. Many wireless phones and
networks use digital technology.
Digital Audio
Digital Audio is a sound signal that has been
converted into numerical values. Digital sound
can be transmitted through multiple channels.
Analog sound can only be transmitted through
two channels.
Coaxial
A single copper conductor, surrounded with
a layer of insulation, covered by a surrounding
copper shield and finally, an insulating jacket.
An unbalanced transmission line with constant
impedance. In audio, this type is commonly used
for low level, line signals terminated in RCA
connectors.
Duplex (half/full)
•
Full duplex is the ability to send and
receive data simultaneously. Duplex is
synonymous with full duplex. Example:
when a modem operates in full-duplex
mode, it can transmit data in two
directions simultaneously. In half-duplex
mode it can transmit data in two directions,
but not simultaneously.
Compression
In audio terms, this is a process of temporarily
or permanently reducing audio data for more
efficient storage or transmission.A temporary
reduction in file size is called ‘non-lossy’
compression, and no information is lost.A
permanent reduction in file size (such as with
MP3 files) is called ‘lossy’ compression, and
involves discarding unnecessary information
which is irretrievably lost.
E
Eco (Eco Standby)
Eco Standby is the most ‘economic’ mode of
the WAC7500 and consumes less than 1W. It is
‘economic’ and environmentally friendly to use
this mode during longer times of non-usage of
the WAC7500.
D
EQ (Equalizer)
dB (Decibel)
A unit of measure used to express relative
difference in power or intensity of sound.
A class of electronic filter circuits designed
to augment or adjust electronic or acoustic
systems. Equalizers can be fixed or adjustable,
active or passive. Many equalizers divide the
spectrum into 3 to 1ꢀ bands.This allows each
section to be either increased or decreased in
amplitude without changing the response of
the rest.
D
DC (direct current)
Direct current or continuous current is the
constant flow of electric charge.This is typically
in a conductor such as a wire. In direct current,
the electric charges flow in the same direction,
distinguishing it from AC (alternating current).
F
Fidelity
DHCP
A term used to describe the accuracy of
recording, reproduction, or general quality of
audio processing.“High Fidelity” (Hi-Fi) is the
goal of every designer.
DHCP stands for Dynamic Host Configuration
Protocol. It is a protocol for assigning dynamic
IP addresses to devices on a network.

FM (Frequency Modulation)
Incredible Surround Sound (Incr.Surr.)
An improved system that creates realistic, three-
dimensional sound fields.These sound fields are
usually achieved with multiple speakers that are
arranged around the listener.
In radio broadcasting: a method of modulation
in which the frequency of the carrier voltage
is varied with the frequency of the modulation
voltage.
Frequency
Input sensitivity
The property or condition of occurring at
frequent intervals. In sound, this simply refers
to the regular occurrence of compression and
rarification of air that we experience as sound.
SPL (sound pressure level) a speaker produces,
given one watt of power, measured from a
one-meter distance at a typical input frequency
(usually 1kHz unless otherwise noted on the
speaker).
Frequency Response
Is the range of frequencies that a speaker
reproduces, lowest frequency to the highest.
While the optimal normal is ꢀ0-ꢀ0,000 Hz
(Hertz), the range of human hearing for
individuals is often much more restricted.
A good full-range speaker system however,
reproduces as much of this range as possible to
cover all variations. Individual drivers are limited
to reproduce only that part of the spectrum
for which they were made, so their response is
limited, but still a necessary point to consider
when designing a complete sound system.
Interface
A device or protocol which facilitates the linking
of any two devices or systems; or when used as
a verb (‘to interface’), the process of linking.
IP address
An IP (Internet Protocol) address is a unique
computer address that enables electronic
devices to communicate with and identify each
other.
K
Kbps
H
Kilobits per second.A digital-data-rate
measurement system which is often used with
highly compressed formats such as AAC, DAB,
MP3 etc.The higher the amount, the better the
quality generally is.
Hi-Fi (High Fidelity)
A method of sound reproduction that
emphasizes the highest possible adherence to
the exact character of the original sound.This
is a principal that must be paramount in every
stage of the recording, transportation, and
recreation of the signal to be fully operational. It
is usually the listener’s equipment wherein this
objective is most seriously compromised.
K
kHz (kilo Hertz)
1000Hz or 1000 cycles per second.
Hz (Hertz)
L
Cycles per second, named after Heinrich Hertz.
LCD (Liquid Crystal Display)
Probably the most common way to show
visual information on non-computer electronic
equipment.
I
Impedance
The resistance to the flow of an electric current
in a circuit.This is effectively the electrical load
that a loudspeaker presents to the amplifier
which drives it and is measured in ohms.
38 EN
Download from Www.Somanuals.com. All Manuals Search And Download.
Lossless compression
O
Ohm
A system for reducing the number of data bits
(density) in a musical signal without corrupting
the original.
Measure of resistance to current (impedance).
The lower the impedance of a speaker, the
harder it is to drive.
M
M4A
P
The audio file format used by Apple in their
iTunes Music Store often appears on your
system with the ‘.m4a’ filename extension. M4A
can produce better audio quality than MP3
using less physical space for the files.
PCM (Pulse Code Modulation)
Pioneering form of digital recording.
R
MHz (Mega Hertz)
One million cycles per second.
RDS (Radio Data System)
RDS tuners can automatically tune in stations
according to the types of music (or talk) they
broadcast. RDS also enables a receiver to
display text messages and even graphics (usually
call letters and format information) that many
FM stations include on a sub-carrier signal
within their normal broadcast signal. Some RDS
equipped tuners can even override with traffic
alerts or emergency broadcasts, during playback
of other media - CD MD, or cassette.There are
other useful features too, many of which are
offered by the growing number of RDS stations.
Midrange
The middle three octaves (more or less) of the
audio band, where the ear is most sensitive,
usually between 160Hz-3kHz.
Mono (monaural)
The operation of an amplifier in one channel
for both input and output. Can refer to an
amplifier with only one channel of amplification
or operating in bridged mode. For low-
frequency amplification applications, it provides
better phase coherence and less distortion than
stereo operation.
RF (radio frequency)
An alternating current or voltage with a
frequency (or carrier wave) above about
100kHz. It is called radio frequency because
these frequencies have a capacity to be radiated
as electromagnetic waves by radio (and
television) stations.
MP3
A file format with a sound data compression
system. MP3 is the abbreviation of Motion
Picture Experts Group 1 (or MPEG-1) Audio
Layer 3.With the MP3 format, one CD-R or
CD-RW can contain about 10 times more data
than a regular CD.
Rip (ripping)
Using a software program that “grabs” digital
audio from a compact disc and transfers it to a
computer hard drive.The integrity of the data
is preserved, because the signal does not pass
through the computer sound card, and need
not be converted to an analog format.The
digital-to-digital transfer creates a WAV file that
can then be converted into an MP3 file.
Mute
A control found on receivers, and some mixers
or signal processing units that silences (mutes) a
signal path, or output.
EN 39

RMS (Root Mean Square)
Stereo
A formula that provides a reasonably accurate
means to measure and compare continuous
AC power.The use of this measure is preferred
when matching system components, like
amplifiers and receivers.
Literally means solid. Usually taken to refer to
two channel stereo, though developments in
digital audio facilitate multichannel stereo.
Streaming
A technique for transferring data such that it
can be processed as a steady and continuous
stream. Streaming technologies are often used
on the Internet because many users do not
have fast enough access to download large
multimedia files quickly, so the client browser or
plug-in can start displaying the data before the
entire file has been transmitted.
S
S/PDIF (SPDIF) (Sony/Philips Digital Interface)
A standard audio-file transfer-format that was
developed jointly by Sony and Philips. S/PDIF
allows the transfer of digital audio signals from
one device to another, without the need to
convert first to analog.This prevents the quality
of the digital signal degrading during transfer to
analog.
Subwoofer
The extra-low frequency drive-unit
(loudspeaker) that can be used to augment
both stereo and surround system.
Sampling rate
The precision with which a digital file describes
the analog sound it represents. Basically, a lower
rate produces files that sound worse and take
up less drive space than those with a higher
rate. CDs have a sampling rate of 44.1kHz,
and DAT machines have a sampling rate of
48kHz. MiniDisc player/recorders with a built-in
sampling rate converter can handle both rates.
T
Treble
High frequencies at the top end of the audio
band i.e. above 3kHz.
Tweeter
The drive unit (loudspeaker) that reproduces
high frequency sounds.
Sensitivity
Volume that a speaker offers for a specific
voltage input, expressed in decibels per watt
(dB/W).
U
UPnP (Universal Plug and Play)
Shuffle
Universal Plug and Play is a networking
architecture developed by a consortium of
companies to ensure easy connectivity between
products from different vendors. UPnP devices
should be able to connect to a network
automatically, handling identification and other
processes on the fly.The standards developed
by the UPnP Forum are media-, platform-, and
device-independent.
A feature that plays audio files (tracks) in
random order.
Signal to noise ratio
Represents the difference between the level of
the audio signal, and any interference.The larger
the figure, the purer the sound.
SPL (sound pressure level)
An acoustic measurement of sound energy.
1 dB SPL is the smallest increment in sound
level to which the average human is sensitive.
Theoretically, 0 dB SPL is the threshold of
human hearing while approximately 120 dB is
the threshold of pain.
USB (universal serial bus)
A hardware interface used to connect devices
such as computer audio players, digital cameras,
and more. USB is UPnP enabled (also called
hot-swappable), meaning that a computer does
not need to be turned off when new devices

are plugged in and the devices do not need to
be configured. USB supports data transfer rates
of up to 60MB per second (in USB 2.0).
offer complete security and is usually used in
conjunction with other security measures such
as EAP.
Wi-Fi
Wi-Fi (Wireless Fidelity) is a wireless
technology brand owned by the Wi-Fi Alliance
intended to improve the interoperability of
wireless local area network products based
on the IEEE 80ꢀ.11 standards. Common
applications for Wi-Fi include Internet andVoIP
phone access, gaming, and network connectivity
for consumer electronics such as televisions,
DVD players, and digital cameras.
V
VBR (variable bit rate)
WithVBR, the encoder takes as much bits as
it needs. So black pictures get few bits and
complex pictures get as much as they need.
While this provides the best quality the final
size cannot be predicted at all.
Volume
Volume is the most common word used to
specify the control of relative loudness of
sounds. It also pertains to the function on many
electronic devices that is used to control the
loudness.
Wireless
Telecommunications using electromagnetic
waves rather than wires or cable to transmit
information.Wireless communication can be
used for free-ranging mobile systems such as
cell phones and global positioning systems
(GPS), which use satellite technology.Wireless
systems can also be fixed, such as LANs that
provide wireless communications within a
limited area (such as an office), or wireless
peripherals such as mice and keyboards.
W
W (wattage)
A measurement of power. In speakers, wattage
is a term that indicates power-handling
characteristics in dealing with electrical voltage
inputs from the amplifier.
WMA (Windows Media Audio)
An audio format owned by Microsoft, is a
part of Microsoft Windows Media technology.
Includes Microsoft Digital Rights Management
tools,Windows MediaVideo encoding
technology, and Windows Media Audio
encoding technology.
WAP (Wireless Application Protocol)
Global protocol used in some wireless devices
that allows the user to view and interact with
data services. Generally used as a means to
view Internet web pages using the limited
transmission capacity and small display screens
of portable wireless devices.
Woofer
The drive unit (loudspeaker) that reproduces
the bass (low) frequencies.
WAV
A format for sound files developed jointly by
Microsoft and IBM. Built into Windows 95 to XP,
which made it the de facto standard for sound
on PCs.WAV sound files end with a ‘.wav’
extension and works with nearly all Windows
applications that support sound.
WPA /WPA2 (Wi-Fi Protected Access)
A Wi-Fi standard that was designed to improve
upon the security features of WEP.The
technology is designed to work with existing
Wi-Fi products that have been enabled with
WEP (i.e. as a software upgrade to existing
hardware), but the technology includes two
improvements over WEP.
WEP (Wired Equivalent Privacy)
All 802.11b (Wi-Fi / wireless) networks use
WEP as their basic security protocol.WEP
