In CCTV system, sometimes it requires one signal of video source(camera) to be sent to multi-terminal device (such as monitor, recorder, etc.).But parallel connection will cause impedance mismatch, signal attenuation, image distortion, circuitry unstable. For the same reason,audio signal transmition faces the same problem. So video audio distribution is needed.Video distribution can amplify 1 channel of video signal into multi-channel uniformly and the video signal from distribution is same with before , that is ......
Video amplifier canamplify 1 channel video signal into multi-channel uniformly, video signal fromamplifier is same to the video signal before amplifier, that is 6Mhz, 1Vp-p,75Ω.
12 series can amplify 8,16 or 32 groups of video signal, every group is 1ch signal input and 2ch or 3ch same signal output.
