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. Speaker Unit reproducing an acoustic wave from an electrical signal which vibrates one or more membranes, the movements creating a sound wave. Stereo Abbreviation of stereophonic. A stereophonic signal is a signal transmitted over 2 channels: one channel on the left & one channel on the right, whereby the sound transmitted is different on each channel. Subwoofer The subwoofer is a speaker which reproduces bass frequencies, & 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) & 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. Watts Peak Power Watts Peak Power represents the peak electrical power delivered by an amplifier to speakers. Watts RMS Power in Watts RMS represents the continuous electrical power delivered by an amplifier to speakers.
