What is the difference between speaker cable and audio cable?

First, the purpose of the audio cable

An audio cable is a connection between audio devices. Audio equipment includes CD players, microphones, computers, DJ equipment, mixers, peripheral equipment, power amplifiers and other electronic or digital products. The connection between them, such as a CD amplifier, a microphone to a mixer, and an audio processor to a power amplifier, requires the use of audio cables. The audio line passes through a small current and low power signal, the impedance of the line is high, easy to be disturbed, so it is generally a shielded line, and the wire diameter is generally relatively thin.

There is a shield inside the audio cable. There are two approaches to shielding. One type is winding shielding, and the other is braided shielding. What are the uses of these two types of shielding?

The wound shield has a better anti-interference effect than the braided shield. However, in repeated use of the winding shield, especially in the rental of audio performances, the winding shielding cable inside is easy to loosen, so the winding shield is often fixed and installed.

Braided shield wire can be used in fixed installation sound engineering and sound rental mobile shows. The braided shielded audio cable is tensile and drag-resistant, has high strength, and the winding shielded microphone cable is softer, which is suitable for repeated retraction and high requirements for wire bending.

Second, the use of the speaker line

The speaker cable is the connection line between the amplifier and the speaker in the audio system.

During the transmission process of the speaker line, the current signal circulating internally is greater than the audio line, the amplitude of the signal is relatively large, and the resistance of the line is required to be low, because the signal is strong, so the speaker line is not shielded. The cross-sectional area of the wire, the thicker the wire resistance will be smaller, that is, the speaker line should be thicker

Speaker cables are divided into sheathed and unsheathed speaker cables. The sheath plays a role in protecting the internal structure of the cable, and the user has beautiful, elastic, soft, smooth, dirt-resistant and easy to care for and other requirements, and outdoor use also has waterproof, antifreeze and other requirements. Unsheathed speaker cables, commonly used in fixed installation projects.

Third: the use of audio line and speaker line of audio system

Usually a professional sound system consists of five parts:

A: Sound source (CD, VOD jukebox, microphone, DJ equipment)

B: Mixer (digital mixer, analog mixer)

C: Peripheral equipment (feedback suppressor, equalizer, audio processor)

D: Power amplifier (analog power amplifier, digital power amplifier)

E: Speakers (line array speakers, column speakers, coaxial speakers, point source speakers, crossover speakers)

The audio cable is used for the connection of A-B-C-D, and the speaker cable is used for the connection of D-E.
