A (Amp/Ampere)

The Ampere (abbreviations: Amp or A) is the unit of electric current, or amount of electric charge per second.

AAC (Advanced Audio Coding)

An audio compression scheme defined as part of the MPEG-2 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.

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.

Album art

Album art is a feature of the WAC7500 that displays the artwork (cover picture) of a music album.This display enables the user to quickly identify a music album.The artwork files for music albums can be downloaded from the Internet.

Amplifier

Bass

 

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.

 

BestBuy®

 

BestBuy® is a membership-based digital music

 

service that allows listeners to subscribe to

 

music through the Internet at a monthly rate,

 

rather than to purchase the music.

 

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).

 

Bluetooth®

 

Bluetooth® is 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 2.4 GHz. For more information, see
