Explanation terms

B
Bit rate
This expresses the read amount per 1 second of
video/audio data recorded in a disc.
D
Dynamic range
The difference between the maximum undistorted
sound level and the minimum sound level that is
discernible above the noise emitted by the device.
F
Finalize
This is processing that enables playing back of disc
of CD, which was recorded using a recorder, by
other players.
M
MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data
compression scheme, using the "MPEG-1" video
compression standard. It compresses the data
volume to about one eleventh its original size while
maintaining sound quality equivalent to a music CD.
MPEG (Moving Picture Experts Group), MPEG-2,
MPEG-4
These are the names for digital compression format
standards used for the encoding of video and audio.
Video standards include "MPEG-1 Video", "MPEG-
2 Video", "MPEG-4 Visual", "MPEG-4 AVC". Audio
standards include "MPEG-1 Audio", "MPEG-2
Audio", "MPEG-4 AAC".
P
Protection circuit
This is a function to prevent damage to components
within the power supply when an abnormality
such as an overload, excess voltage occurs or
temperature for any reason.
In this unit, the power indicator blinks and the unit
enters standby mode when an abnormality occurs.
24
S
Sampling frequency
Sampling involves taking a reading of a sound wave
(analog signal) at regular intervals and expressing
the height of the wave at each reading in digitized
format (producing a digital signal).
The number of readings taken in one second is
called the "sampling frequency". The larger the
value, the closer the reproduced sound is to the
original.
Speaker impedance
This is an AC resistance value, indicated in Ω
(ohms). Greater power can be obtained with this
value smaller.
W
WMA (Windows Media Audio)
This is audio compression technology developed by
Microsoft Corporation.
WMA data can be encoded using Windows Media ®
Player Ver.7, 7.1, Windows Media ® Player
for Windows ® XP and Windows Media ® Player 9
Series.
To encode WMA fi les, only use applications
authorized by Microsoft Corporation. If you use
an unauthorized application, the fi le may not work
properly.
