Technology
System for transmitting sound over three channels, with 2 channels reproducing medium and high range frequencies and 1 channel reproducing bass frequencies.
Speaker
Unit reproducing an acoustic wave from an electrical signal which vibrates one or more membranes, the movements creating a sound wave.

Line input
Analog audio input designed to receive an unamplified sound signal. There are 2 line levels: the general public line level, at -10dBv: this is the signal output level of a Hi-Fi component connected to an amplifier via a connector known as a line input. The professional line level, at +4dBu, is much more powerful, and is used to connect studio or public-address (PA) equipment.

Headphone plug
Stereo audio output allowing for the connection of stereo headphones. A headphone plug uses a connector in 3.5mm mini-jack format.

Satellite
Satellite is the name given to a speaker which does not reproduce bass frequencies: this speaker is therefore the satellite to a subwoofer. In a X.1 kit (2.1, 4.1, 5.1 , 6.1 or 7.1), the digit before the point 1, i.e. the 2, 4, 5, 6 or 7, represents the number of satellites in the speaker kit.

Stereo
Abbreviation of stereophonic. A stereophonic signal is a signal transmitted over 2 channels: one channel on the left and one channel on the right, whereby the sound transmitted is different on each channel.

Dome-shaped driver
Speaker driver with a dome shape for enhanced sound distribution.

Driver
A driver is a device which transforms a signal into another signal: a speaker is a driver which transforms an electrical signal into a sound signal.

Watts Peak Power
Watts Peak Power represents the peak electrical power delivered by an amplifier to speakers.
