RCA视频隔离器监视视频反干扰

RCA Video Isolator Monitoring Video Anti interference AV Video Filter Eliminating Strong Electric Horizontal Snowflake Noise Suppressor

Product Overview:

接地环路视频隔离器, also known as ground loop audio video isolator, 主要用于消除对CCTV视频的干扰 (或音频) 接地环路电压引起的信号. Ground loop/ground loop interference is an electronic interference phenomenon mainly caused by the different potential between the two terminals of a video cable. Due to the selection of different video signal reference ground potentials for video cables, the interference caused by AC current circuit mainly occurs in the shielding layer of video cables and the shell of video equipment.

通常情况下, 屏蔽层的电压为0V. When the local circuit/ground loop phenomenon exists, 水平将在0V左右波动, and more seriously, it will cause serious distortion and tearing of the video signal, accompanied by interference phenomena such as horizontal lines, mesh lines, and snowflakes. 当视频信号传输距离超过 100 米, it is easy to generate high ground loop voltage. 如果接地环电压太高, it may even cause the equipment to be burned.

Single channel video ground circuit isolation anti-interference device, which can handle balanced audio or balanced video signals that need to be isolated from the input and output calmly. 与此同时, it also integrates a common mode interference filter internally to eliminate interference signals from the transmission cable. The converted non balanced signals can be directly connected to the unbalanced input end of audio and video.

它经常用于监视视频, home audio, 电脑室, recording rooms, 逆转图像的汽车, KTVs, 酒吧, car audio, and other image interference caused by common interference, 例如条纹, 雪花噪音, horizontal lines, 图像抖动, 网, image tearing, and a series of common ground interference.
