Audio/Video cables (A/V cables) are connecting wires used to transmit audio and video signals. Their core function is to ensure stable transmission of audio and video data from signal sources (such as TVs, computers, and audio systems) to output devices (such as monitors and speakers), avoiding signal loss or interference. Core Categories and Features According to the type of transmitted signals and application scenarios, common categories are as follows: Audio Cables: Specifically for transmitting audio signals 3.5mm Audio Cable: Universal type, connects mobile phones/computers to headphones/speakers, supporting stereo sound. RCA Audio Cable (Red/White Phono Cables): Commonly used for older devices, with red for right channel and white for left channel, transmitting analog audio. XLR Cable: Dedicated for professional audio equipment (such as microphones and stage audio systems), featuring strong anti-interference and stable transmission. Video Cables: Specifically for transmitting image signals HDMI Cable: Currently the most mainstream, supporting simultaneous transmission of high-definition/4K/8K video and audio. Suitable for TVs, projectors, game consoles, etc. VGA Cable: Commonly used for older computers and monitors, only transmitting analog video without audio, with limited image quality (max 1080P). DP Cable (DisplayPort): Commonly used for professional e-sports and high-end devices, supporting higher resolution and refresh rate with strong compatibility. All-in-One Audio/Video Cables: Transmit both audio and video simultaneously to reduce wiring hassle. HDMI cables and DP cables fall into this category.
