for low level, line signals terminated in RCA connectors.
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
D
dB (Decibel)
A unit of measure used to express relative difference in power or intensity of sound.
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).
DHCP
DHCP stands for Dynamic Host Configuration Protocol. It is a protocol for assigning dynamic IP addresses to devices on a network.
Digital
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.
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
mode, it can transmit data in two directions simultaneously. In
E
Eco (Eco Standby)
Eco Standby is the most ‘economic’ mode of the MCi300 and consumes less than 1W. It is ‘economic’ and environmentally friendly to use this mode during longer times of
EQ (Equalizer)
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 12 bands.This allows each section to be either increased or decreased in amplitude without changing the response of the rest.
F
Fidelity
A term used to describe the accuracy of recording, reproduction, or general quality of audio processing. “High Fidelity”
FM (Frequency Modulation)
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
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.
Frequency Response
Is the range of frequencies that a speaker reproduces, lowest frequency to the highest. While the optimal normal is
