<b>Technology</b>

<b>Speaker</b>

Unit reproducing an acoustic wave from an electrical signal which vibrates one or more membranes, the movements creating a sound wave.

<b>2.1</b>

System for transmitting sound over three channels, with 2 channels reproducing medium and high range frequencies and 1 channel reproducing bass frequencies.

<b>Satellite</b>

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.

<b>Subwoofer</b>

The subwoofer is a speaker which reproduces bass frequencies, and is often larger than other types of speakers as bass frequencies require larger membranes than is the case with high or medium frequencies. A single subwoofer is most often included in a speaker kit: as bass frequencies are transmitted all around the membrane (omnidirectionally) and not just in front of the membrane, a single subwoofer is sufficient to provide rich bass sound all across an area, as long as it is powerful enough. In a X.1 kit (2.1, 4.1, 5.1, 6.1 or 7.1), the digit after the period, i.e. the 1, signifies that 1 subwoofer is included.

<b>Watts RMS</b>

Power in Watts RMS represents the continuous electrical power delivered by an amplifier to speakers.

<b>Watts Peak Power</b>

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

<b>Headphone plug</b>

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

<b>Line input</b>

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.

<b>Magnetic shielding</b>

Magnetic shielding shields against the magnetic field generated by speakers, for example. If a speaker is touching a CRT screen (television or computer), magnetic shielding is necessary to avoid disturbing the display.
