They are used to transmit sound signals from audio amplifiers to speakers. Like the normal wires that we are used to in our everyday lives, are speaker wires dangerous as well? Can speaker wires shock you? Most people cannot tell with certainty the true extent of electrical hazards posed by speaker wires.
Speaker wires cannot shock you. The amount of current that passes through speaker wires is very low and not strong enough to cause an electric shock to humans beings. There is voltage in speaker wires. Any medium that carries or transports electricity has some amount of voltage inside it.
In speaker wires, the amount of voltage that runs through them is dependent on the amplifier power. Speaker wires carry whatever level of voltage that comes out of the amplifier they are connected to. For a watt amplifier that is driving an 8 Ohm speaker, the voltage that will be transmitted through the speaker wires would be about 30 volts. This voltage is entirely dependent on the power rating of the amplifier.
This means an amplifier with a higher power rating will drive a relatively high voltage through the speaker wires connected to it. So yes, a speaker wire connected to a powered amplifier has some voltage running through it. With speaker wires, the voltages involved are very low.
This voltage is usually quite small that most people would not feel it. Thus, electric shock is rare from appliances and wires with low voltages passing through them. Speaker wires are not plugged into a wall socket or an extension socket. Due to this, they do not carry the same high level of current as normal power cords. Generally, audio signals that run through speaker wires are not strong enough to be dangerous when touched. However, this is not enough reason to be complacent when handling speaker wires.
Speaker wires are made of two stranded wires, usually made of copper. These copper wires are heavily insulated by plastic such as PVC, and as such, as long as the currents stay inside the wires, it poses no danger to people. With electricity being confined within the speaker wires at all times, there is little risk of electrocution. With that being said, due to the low current that passes through speaker wires, even when the naked speaker wires come in contact with the human body, it will not pose any harm.
There is a belief that, whenever wires and human beings come together, there is always the potential for injury or harm to occur. This potential for injury can be from trailing wires or electrical shock.
In the case of speaker wires, this danger results from trailing wires and no risk of electrical shock. This results in a diminished sense of bass response as you have essentially created no signal. This effect is not as noticable at higher frequencies because of the shorter wavelenghth of the signal as it ascends in frequency. To check if your system is in phase with itself do this: place the two speakers we're talking stereo here not home theater multichannel equal distance apart, and not more than eight feet apart; put your FM tuner on a frequency where you will find a single announcer's voice if this is not possible[?
If the speakers are in phase with one another you will hear a distinct position where the signal is centered between the two speakers. Do not change any connection. If the sound seems to come from no distinct position but instaed seems to come from everywhere, the speakers are out of phase. Reverse the connection at one speaker only and repeat the test. Neither condition will damage your amplifier unless you have shorted the wires together in the process.
Dave Well-Known Member. The difference is that the thicker gauge wire 16 can be used for a longer run. In a round shape, it can be used more aggressively in the same manners as the gauge above, and in a square shape gauge can be used to make frames and wire settings for smaller cabochons and faceted stones. It is also used to make individual jump rings and head pins, as well as wrapping the tops of briolettes.
It pertains to the diameter of the wire. The lower the AWG, the more current capacity it can carry. The lower the gauge number, the thicker the wire.
