RCAビデオアイソレータ監視ビデオ干渉

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

製品概要:

グランドループビデオアイソレーター, also known as ground loop audio video isolator, 主にCCTVビデオへの干渉を排除するために使用されます (またはオーディオ) グランドループ電圧によって発生する信号. 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.

通常は, シールド層の電圧は0Vです. When the local circuit/ground loop phenomenon exists, レベルは0Vを中心に変動します, 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. 映像信号の伝送距離を超える場合 100 メートル, it is easy to generate high ground loop voltage. グランドループ電圧が高すぎる場合, 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. 同時に, 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.

監視ビデオなどでよく使われています, home audio, コンピューター室, recording rooms, 車 バックの画像, KTVs, バー, car audio, and other image interference caused by common interference, ストライプなどの, 雪片ノイズ, horizontal lines, 画像のジッター, メッシュ, image tearing, and a series of common ground interference.
