Speaker Wire is mainly used to connect power amplifiers and main speakers and surround speakers in home theaters, that is, to connect power
amplifiers and speakers. Compared with video cable and Audio Cable, its current signal is relatively large. Due to the large signal amplitude,
Speaker Wire often has no shielding layer.
For this kind of wire, the key is to reduce its resistance, because the output resistance of modern power amplifiers is very low, so the requirements
for the Speaker Wire will also increase, such as the use of large cross-sectional area or multi-stranded wire. What is the difference between
Speaker Wire passes the power signal directly. Because the current is large, the copper core of the wire is usually thick. In order to ensure high
frequency passage and reduce resistance attenuation, most of them are silver-plated, gold-plated or oxygen-free copper wires. Speaker Wire is
Generally, oxygen-free copper is the positive electrode, and tin-plated copper is the negative electrode. The color of the double skin is red, both
sides are brass-colored, and the oxygen-free copper core is marked with a red line on the positive side. Speaker Wire is composed of the
corresponding number of copper cores. Generally, the more copper cores, the better the effect and the higher the price. However, if it is a
household wire or ordinary speaker wire, 200 to 300 is actually enough. Up.
Audio Cable is a wire used to transmit electro-acoustic signals or data. It passes signals with low current and low power. It has high impedance
and is easy to be interfered. Therefore, it is generally a shielded wire, and the wire diameter is generally relatively thin.
At present, the oxygen-free copper speaker wire, also known as gold and silver wire, is more mainstream and has a lower resistance. Gold and silver
The most important thing is to reduce the resistance of the line. The impedance of the power amplifier is very low when it is output.
Audio Cable passes low-power and small-current signals, and has high impedance, which is easy to be interfered. Therefore, it is generally a shielded wire and
mainly used in various types of speakers, PA projects, home theater connections, and public space broadcasting systems.
