RCA Video Isolator Monitoring Video Anti interference AV Video Filter Eliminating Strong Electric Horizontal Snowflake Noise Suppressor
Обзор продукта:
Видеоизолятор контура заземления, also known as ground loop audio video isolator, в основном используется для устранения помех видео видеонаблюдения (или аудио) сигналы, вызванные напряжением контура заземления. 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.
Обычно, напряжение экранирующего слоя 0В. When the local circuit/ground loop phenomenon exists, уровень будет колебаться около 0В, 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. Когда расстояние передачи видеосигнала превышает 100 метры, it is easy to generate high ground loop voltage. Если напряжение контура заземления слишком высокое, 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. В то же время, 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.
Его часто используют в видео наблюдения., home audio, компьютерные залы, recording rooms, «автомобиль задним ходом»: изображения, KTVs, бары, car audio, and other image interference caused by common interference, такие как полосы, шум снежинки, horizontal lines, дрожание изображения, сетка, image tearing, and a series of common ground interference.
