The red, white and yellow av wires are the audio interface (red and white wires, forming the left and right channels) and the video interface (yellow).
Since the AV output is still a video signal that mixes luminance and chrominance, the display device is still required to perform luminance and color separation, and decoding can be imaged. Such an approach will inevitably cause loss of image quality, so the quality of the AV interface is still not satisfactory. It is very simple to connect, just connect the AV cable of 3 colors to the interface of the 3 colors of the TV. In general, the AV interface realizes separate transmission of audio and video, and can avoid image quality degradation caused by mutual interference between audio and video in imaging. The AV interface is widely used in TV and DVD connections and is one of the necessary interfaces for each TV.
The problems that the AV cable should pay attention to during use:
1 Different functions of the wire can not be mixed at will, for example, can not use the audio wire to replace the coaxial wire;
2AV cable should be bent as much as possible during use, and it is better to stay away from the power supply;
The 3AV wire should be as short as possible on the premise that it is sufficient, and the extra length will only increase the signal loss;
The size of the 4 speaker cable should be selected according to the size of the audio power. Too small, the signal transmission is stagnation, the speaker can't make a good sound; too much, the signal loss increases, the burden of the power amplifier increases, and the speaker can't make a good sound.
The 5AV cable must be fastened to the outside. If the contact is bad (such as collapse, etc.), it will cause the sound of the sound, and serious components will burn out.
After the 6AV cable has been used for a certain period of time, the metal terminals and the metal core may be oxidized (ie, "aged"), which may affect the sound effect and should be replaced according to the actual situation.
Starte AV high-definition video wire conductors use high-purity oxygen-free copper to ensure signal transmission. High-density double-shielded protective layer is used to prevent external interference and keep the signal pure and noise-free. Made of oxygen-free copper and plastic, the body is soft and flexible. High-shielded fidelity design, strong anti-interference performance, good transmission signal effect. This product wire is wound and shielded for audio and video signal transmission and interconnection between various electrical appliances.
Starte AV audio and video cable, using soft rubber cable to reduce attenuation and extend plug life.
It adopts high-shielded fidelity design, strong anti-interference performance and good transmission signal effect. It is suitable for audio signal connection and interconnection between set-top boxes, video cameras, power amplifiers, VCDs, DVDs, video recorders, etc. and TV sets.
DVD-VIDEO is full of strong colors, strong light and dark levels and the highest level of image quality, ideal for HIVI enthusiasts.
