With the popularization of audio devices and the development of the music industry, audio cables have become an indispensable part. They are the main medium for transmitting audio signals and play an important role in connecting different devices. This article will introduce the basic knowledge and application fields of audio cables, as well as how to choose audio cables that are suitable for your own needs.
1、 Basic knowledge of audio cables
What is an audio cable?
An audio cable is a type of cable used to transmit audio signals. It usually consists of multiple wires (usually copper wire), each of which is wrapped in a layer of insulation material, which is then wrapped in a layer of insulation material and finally protected by a protective sheath.
Type of audio cable
There are many types of audio cables, but the most commonly used types are balanced and unbalanced cables.
A balanced cable is composed of three wires, two of which transmit audio signals and the other wire is used for shielding. This type of cable can reduce the impact of interference signals, so it is more commonly used in high-quality audio transmission.
Non balanced cables only have two wires, one for transmitting audio signals and the other for shielding. It is simpler than a balanced cable, but it is susceptible to interference.
Characteristics of audio cables
The characteristics of audio cables mainly depend on their type and material. Generally speaking, a good audio cable should have the following characteristics:
(1) Low noise: An excellent audio cable should minimize the impact of external interference signals on the audio signal as much as possible.
(2) Low distortion: A good audio cable should be able to transmit high fidelity audio signals without additional distortion.
(3) High fidelity: excellent audio cables should be able to accurately transmit audio signals without signal deformation due to signal loss.
(4) High reliability: Audio cables should be able to be used for a long time and will not fail due to material aging or external interference.
