What kinds of audio cables are there?

Problem 1: Wires and jumpers of common audio systems. Which devices in the audio system must rely on their connecting tools to realize communication and transmission, namely wires and connectors? It plays a very important role in the whole audio system. Nowadays, there are many kinds of connecting wires and connectors used in professional audio systems. Here, Shenzhen Yihe Audio Company briefly introduces the common types of wires and connectors:

Wire classification of various common professional audio:

1, professional audio line

At present, the common professional audio cables have two cores, three cores, four cores and five cores, which can be used to transmit high-quality audio signals because of their good shielding effect. At present, professional microphones generally use wires with more than three cores, which has strong anti-interference ability and can be transmitted over a long distance. Of course, this wire can also transmit other signals, such as DMX5 12 control signal of computer lamp.

2. Coaxial cable

This kind of coaxial cable is generally used for video, and some of it is also used as audio cable. Because of its poor anti-interference ability and its design is not mainly used to transmit audio signals, it is not suitable for long-distance audio signal transmission.

3. Centralized cable

That is, multiple signal lines are wrapped in the same protection tube, which is usually used to connect the inside of the system to reduce the number of independent wires. Now it is also used in special fields such as TV ob vans and underground burial. This kind of thread is generally processed by professional manufacturers, and the quality is more guaranteed.

4. Optical fiber

Many CD, MD and other recording and playback devices often use transmission lines to transmit digital signals. With the popularization of digitalization, there will be more and more applications of optical fiber in sound system in the future.

5, MIDI line

Usually five-core wires are used to transmit information about MIDI, but now these wires are mostly used for keyboards, effectors and other devices. Usually, you can buy all kinds of commonly used MIDI lines to connect finished products; The transmission quality is also very good; So I won't go into details here.

6. Other categories

There are also some special wires, such as the multi-core network cable originally used to connect the network in the computer song-ordering system, which can also be used to transmit audio and video to realize the computer automatic on-demand function.

Classification of various common professional audio connectors:

1、XLR

Commonly known as cannon joint, this joint consists of three contacts, namely 1-ground; 2- hot end (+level); 3- cold end (-level), of course, some equipment stipulates that 3 is hot end (+level); 2 is the cold end (-level), which depends on the instruction manual of the equipment. Canon connector is the most widely used connector in professional audio system, which can be used to transmit various audio signals in audio system. Generally, the balanced input and output terminals are connected through Canon connectors. In a sense, the use of cannon connectors is also one of the characteristics that distinguish professional audio systems from civil audio systems. Its advantages are:

A, the balanced transmission mode has strong anti-interference ability, which is beneficial to the transmission of long-distance high-fidelity signals;

B, with spring locking device, reliable connection, not easy to pull off;

C, the connector specifies the signal flow direction, so as to prevent connection errors;

Cannon plugs can be divided into male plugs and female plugs, and sockets can also be divided into male plugs and female plugs. The contact of the male plug is a pin, and the contact of the female plug is a jack. According to the international practice, the male plug or socket is used as the input end of the signal; Take the female plug socket as the signal output end. Common XLR connectors are as follows:

2、RCA

Commonly known as lotus connector in China (because some types of RCA connectors look like lotus petals), it consists of two contacts, namely the hot terminal (+level); Cold-end grounding (-type), connected by coaxial cable, can also use multi-core audio cable, commonly used in general household audio equipment. Because its length is about 3.5cm, I usually call it a 3.5 cm plug.

RCA plugs can be divided into male plugs and female plugs; Common RCA connectors are as follows:

3、TRS

Generally called stereo connector, it consists of three contacts, namely: the head end (+level); Ring end (-horizontal); The ground wire is about 3.5cm in length when used in small headphones or notebook computers, and it is 6.35cm in length when most used in professional audio. At present, this kind of plug is mostly used for high-resistance input and plug-in socket of professional mixer, and it is also used in other audio equipment. Common TRS connectors are as follows:

4、TS

Usually called single tone (acoustic) connector, this connector consists of two contacts, namely ... >; & gt

Question 2: What kinds of audio lines are there? 2×30 branch 2×0.24 40 2×50 branch 2×0.4 70

2×70 branches 2×0.6 100 2× 100 branches 2×0.8 140.

2× 150 branches 2× 1.2 220 2×200 branches 2× 1.6 300

2×250 branch pipes 2×2.0 340 2×300 branch pipes 2×2.4 380

2×380 branch pipes 2×3.0 460 2×500 branch pipes 2×4.0 540

The wire diameter is directly proportional to the power of the speaker; The wire diameter is proportional to the distance from the power amplifier to the speaker, and the total impedance of the wire should not be greater than 5% of the speaker impedance.

Question 3: What types of audio cable interfaces do the most common audio plugs have? 3.5mm and showerhead, and general clips or terminals for connecting speakers.

Question 4: What are the types of audio cable connectors? 1. Two-core or three-core plug or socket.

There are three diameters: φ 2.5 mm, φ 3.5 mm and φ 6.5 mm, which are generally used for microphone input, external speaker output or earphone output. Two cores are used for mono or unbalanced connection, and three cores are used for stereo or balanced connection.

2.TX concentric plug socket

Also known as lotus plug, or electric disc plug, it is widely used at present.

3.YC type 5-core plug socket

Also known as German din standard plug and socket, it is generally used for the connection between cassette recorder and power amplifier, as well as the input and output lines of recorder.

4. Canon plugs and sockets

It is mostly used for input and output connection of mixers, peripherals and power amplifiers. Usually used to balance connections.

At present, only these four kinds are widely used. I looked through a lot of information and couldn't find the fifth one.

Question 5: What are the types and specifications of speaker cables? Hello, there are many transparent speaker wires, most of which are based on the ratio of pure copper to copper wire. Specifications are generally determined by the number of wires, such as 100 or 200. Refers to the number of copper wires, there are many kinds, such as pure copper, oxygen-free copper, crystalline copper and so on.

Question 6: What are the specifications and models of audio cable? The speaker cable has two cores and four cores, and the microphone cable has balance and imbalance.

Question 7: What kind of cable does the computer need to connect the stereo? Which jack is plugged in? 10 There is also a green jack behind the mainframe.

Question 8: Which speaker cable is better? 1. Two-core or three-core plugs or sockets with diameters of φ 2.5 mm, φ 3.5 mm and φ 6.5 mm are generally used for microphone input, external speaker output or earphone output. Two cores are used for mono or unbalanced connection, and three cores are used for stereo or balanced connection. 2.TX concentric plug socket, also known as lotus plug, or electric disc plug, is widely used at present. 3.YC 5-core plug socket, also known as din standard plug socket in Germany, is generally used for the connection between cassette tape recorder and power amplifier, as well as the input and output circuit of tape recorder. 4. Cannon plugs and sockets are mostly used to connect the mixer with peripherals and power amplifiers. Usually used for balanced connection, only these four kinds are widely used at present. I looked through a lot of information and couldn't find the fifth one.

Question 9: What's the name of this audio line? This is not like a connecting wire, it should be wire control. When the speaker is inconvenient to operate, or it is difficult to arrange keys on the speaker, the wire control mode is adopted.

In recent years, new products and similar products mostly use wireless remote control.

Question 10: What's the difference between speaker cable and ordinary cable? First of all, the material, it uses pure metal, relatively small resistance, relatively small audio current loss; Furthermore, insulation, generally speaking, the wires used to transmit audio current should be absolutely parallel, resulting in less electromagnetic interference.

Ordinary wires are not strict with the above requirements, and the requirements can be reduced according to the cost.
