What Is The Difference Between Speaker Cables And Audio Cables?

Speaker cable, is mainly used for the connection of amplifiers to main speakers and surround speakers in home theatres. Compared to video and audio cables, it has a relatively large current signal in circulation and because of the large signal amplitude, speaker cables are often unshielded. For this kind of wire, the key is to reduce its resistance, because the output resistance of modern amplifiers is very low, the requirements of the speaker wire are increased, you can use a large cross-sectional area or multi-strand stranded speaker wire.

Speaker Cables, Audio Cables

Speaker cables pass directly through the power signal, because of the high current passing through, the copper core of the line will be thicker, in order to ensure that high frequencies pass through and reduce resistance attenuation, mostly silver-plated, gold-plated or oxygen-free copper wire.

What Is The Difference Between Speaker Cables And Audio Cables

Generally oxygen-free copper is the positive pole and tinned copper is the negative pole. The double skin is red in colour, both sides are brass coloured. The positive side of the oxygen-free copper core is marked with a red line. Speaker cable consists of the corresponding number of copper cores, the higher the number of copper cores, the better the result and the higher the price, but if it is use for family or ordinary speaker, the choice of 200 to 300 is enough.

Audio cables are used to transmit electro-acoustic signals or data, through small currents and low power signals, due to the high impedance and susceptibility to interference, so are generally shielded cables, the wire diameter is generally thin. The types of audio cables can be divided into two main categories, “audio electrical signal cables” and “audio optical signal cables”. In the market is commonly used is the audio signal cable. The general specifications are: 3.5mm male to male audio extension cable, 3.5mm male to female audio extension cable, double lotus head audio cable, etc.

The Difference Between Speaker Cables And Audio Cables

Speaker cables mainly transmit power signals, so they are required to have excellent conductivity and high quality transmission. For the time being, oxygen-free copper speaker cables, also known as metallic yarn, are more mainstream and have a lower resistance. Audio gold and silver wire is usually unshielded because the current signal circulating in it is greater than that of audio and video wire, and the signal has a high amplitude. The most important thing is to reduce the resistance of the wire, the impedance of the amplifier when it is transmitted there is very low.

Audio cables pass through low power and low current signals and have high impedance, making them susceptible to interference, so they are usually shielded and the wire is thin. Audio cables are usually shielded, but speaker cables are often unshielded, and the key is to reduce resistance.

The audio electric signal cable can be used as a connection cable between the equipment connecting the music output signal of mobile phones, CD players and MP3 to the amplifier. Speaker cables are mainly used for all types of speakers, PA projects, home cinema connections and public space broadcasting systems.
