TroubleshootingExplanation terms

Bit rate

This expresses the read amount per 1 second of

video/audio data recorded in a disc.

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.

Finalize

This is processing that enables playing back of disc

of CD, which was recorded using a recorder, by

other players.

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”.

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.

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.

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.
