Kramer SV-5N is a professional video distribution amplifier (DA) designed to take one composite video or S-Video source and split it into multiple identical outputs without signal loss.

In simple terms:
1 video in → 4 or 5 identical outputs out (depending on version/config)

It was used in broadcast studios, surveillance systems, editing rooms, and AV installations.
