    What is the longest transmission distance of the VGA cable

    The history of the VGA interface can be traced back to 1987. The blue plug is generally used, and it is also the most recognizable interface. The VGA interface has 3 rows of pins, 5 in each row, totaling 15 pins. Our childhood memories—Big head monitors use VGA ports. The VGA interface transmits analog signals with weak anti-interference ability and supports a maximum resolution of 1080P. The transmission distance of the 3+4/6 VGA cable is 15-30m. The oxygen-free copper VGA cable with thick conductor and good shielding can reach a transmission distance of 30m, and the inferior VGA cable over 15m will cause image quality problems such as smear and blur.

    Classification and Main Functions of Home Audio

    Home audio is usually divided into pure audio and home theater audio. Pure audio is also called HI-FI audio, which is composed of pure power amplifier (only two channel output), speakers and disc player, and is generally used to listen to music and songs. Home theater audio is also called AV combination audio, which can play music and songs in two channels, as well as multi-channel discs. “Audiophiles” generally play pure audio, and mainly listen to Western classical music. Therefore, a good audio cable is essential for connecting speakers and players, and vention audio cable is your best partner.

    The Necessity Of Choosing A Reasonable AV Cable For Audio

    The AV cable, which is responsible for the audio transmission signal, plays an important role in the entire audio system. A good audio cable and a poor audio cable not only have different materials, but also have different internal structural principles. Therefore, there are certain differences in signal transmission performance and resistance to external electromagnetic interference. High-end audio is equipped with high-end audio cable, mid-range audio is equipped with mid-range audio cable, and low-end audio is equipped with low-end audio cable. This is the most reasonable investment principle to ensure the best performance of audio. Someone bought a high-end audio, but chose a low-end audio cable to save money. This is no different from driving a Mercedes-Benz to a gas station and adding the cheapest 90# gasoline. On the surface, it saves money, but the actual effect is not good. The best performance of the car. Usually in the high-end audio configuration, the investment ratio of the audio line is 15%~30%. Even for ordinary audio, you cannot use a too low-grade AV cable, because this will not only attenuate the signal, but the transmitted signal is susceptible to external electromagnetic interference, which will eventually cause sound distortion.

  • Precautions For AV Cable Use And Maintenance

    Precautions For AV Cable Use And Maintenance

    If you can pay attention to the following aspects of the AV cable in use, it will not only improve the sound performance, but also extend the service life of the cable: 1. Cables with different functions cannot be mixed at will, for example, audio cables cannot be used instead of coaxial cables; 2. When using the AV cable, try not to bend it and keep it away from the power supply; 3. The AV cable should be as short as possible if it is sufficient, the excess length will only increase the signal loss; 4. The size of the speaker cable should be selected according to the size of the audio power. If it is too small, the signal transmission will be delayed, and the speaker will not produce good sound; if it is too large, the signal loss will increase, and the burden on the power amplifier will increase, and the speaker will also not produce good sound; 5. The connection between the AV cable and the outside must be tight. If the contact is poor (such as collapse, etc.), it will cause noise from the speaker, and in serious cases, it will cause the components to burn out; 6. After the AV cable is used for a certain number of years, the metal terminals and the metal core may be oxidized (ie “aging”), which will affect the sound effect, and should be replaced according to the actual situation.

    The Relationship Between Optical Fiber Cable, Coaxial Cable And Decoder And Power Amplifier

    Disc players can “read codes” and “decode”, but in order to reduce costs, their decoding functions are generally relatively primitive. To increase the level of “decoding” and make the sound more beautiful, it is necessary to be equipped with an independent decoder and a power amplifier with decoding function. Optical fiber cables are needed between the disc drive and the decoder, and between the disc drive and the decoding power amplifier. It is connected with a coaxial cable and is responsible for transmitting the digital audio signal “read” from the discplayer to an independent decoder or a power amplifier with decoding function to “decode” it into an audio signal. This transmission method is often used in high-end audio systems.
