What is speaker level hookup?
top Speaker level signal has been amplified to provide the voltage and current necessary to power the speaker. In a basic stereo system there will be a left and right channel, each of which will consist of a positive and negative connection. Many receivers add a second set of outputs for extension speaker use. A Dolby Pro-Logic Receiver has five speaker outputs for left, right, center and two rear speakers. Newer multi-channel systems utilize even more channels. 7.1 for example consists of left-center-right, two sides and two rears plus subwoofer (LFE) channel. Because the speaker cables are carrying an amplified signal, they must be of sufficient thickness to carry the signal without excessive resistance. The longer the cable run, the more resistance. Cable thickness is measured in gauge, with the lower numbers indicating thicker wire. 18gauge cable is the thinnest that is recommended for speaker use. If the wire has too much resistance, the amplifier will not have as tight a control
