In daily life, we have seen and listened to a lot of wonderful music, they can make people happy, can make people sad, can make people dance unconsciously. It can soothe our wounds in times of pain, and give people hope in times of despair. The power of music is infinite, so have you really considered how music is transmitted? Today we will briefly understand what an audio connector is.
Audio connectors are a set of connectors used for audiovisual applications-RCA and phono. It is used in all aspects of our lives, and there are many types. Although these cannot really be considered to belong to the same series, all kinds of USB connectors are like this, and we will think that they are all the same. USB products have evolved from version 1.0 to version 3.1. During this period, there are some processes, and there is no signal loss in the process of collecting and recording the echo. The new specification is compatible with the previous version. However, the new interface requires new cables and connectors, as well as transmission distance data throughput. The development process of the video surveillance system has gone through three different stages: the collection, transmission, and storage of video and audio signals are all in analog form with the highest quality. A video compression card and corresponding DVR software are installed in the video surveillance system. Different types of video cards can be connected to 1/2/4 video channels to support real-time video and audio.
You might immediately recognize the 1/8" version of this connector as a plug at the end of a pair of headphones. These connectors are actually available in three common sizes: 1/4 (6.35mm), 1/8 (3.5mm), and 2.5mm 1/4 size connectors have many uses in the professional audio and music world. Most electric guitars and amplifiers have 1/4 tip sleeve (TS) jacks and 1/8 tip ring sleeve (TRS) as MP3 players or Connectors for headphones or audio output signals on computers are very common. Some mobile phones will provide a 2.5 mm tip ring sleeve (TRRS) jack for connecting headphones. The headphones also include a microphone for hands-free communication.
The availability of these connectors and cables makes them very suitable for general-purpose connection applications. For example, before USB, Texas Instruments’ graphing calculators used 2.5mmTRS connectors as serial programming connectors. It should be remembered that the tip sleeve connector type is not designed to carry the power supply; during the insertion process, the tip and the sleeve may be shorted together instantly, which may damage the power supply. The lack of shielding makes it unsuitable for high-speed data, but low-speed serial data can be transmitted through these connectors.
The RCA connector has been the first choice for household stereo connectors for decades and was introduced by RCA in the 1940s for household phonographs. It was replaced by HDMI in the audio and video field, but the widespread use of connectors and cables makes it an ideal choice for home systems. There is still a long time before it becomes obsolete.
The female RCA connector can usually be found on the device, but an extension cord or conversion cord with a female jack can be found on it. Most RCA connectors are connected to one of four signals: mainly component video (PAL or NTSC, depending on where the device is sold), composite video, stereo, or S/PDIF audio.
Motherrca connector for the video signal. Usually, NTSC or PAL video signal connectors are yellow. You can usually find male RCA connectors and male RCA plugs on cables. Red and white are commonly used in audio applications, and red indicates the "correct" audio channel.
