Differential Video Line Amplifier /DA | Kramer Electronics 123V

!105V - (1:5 Video Distribution Amplifier) can be serially connected between the output of the amplifier and several acceptors for video distribution. The 105V splits a single video input source into five identical outputs. The 105V uses an external 12VDC power source, and therefore is suitable for fieldwork as well. The 105V uses state of the art technology and microchip design, boasting a signal bandwidth of over 200MHz, thus making it suitable for the most demanding applications.

!SP-11- (Video/Audio Processor) can be serially connected between the output of the 123V and the acceptor for video control/correction. The machine provides camera control and luminance/white balance correction. It is also capable of performing composite to Y/C conversion and bi- directional Transcoding. The machine allows full control over the video signal: video gain down to full fade, log or linear definition control, log or linear contrast control, color saturation control, black level control, red, green and blue controls and a screen splitter control for “before-after” comparison. The input control is "audio-follow-video".

!VIDEO TESTER - A new, unique, patented, indispensable tool for the video professional, the Video Tester is used to test a video path leading to/from an amplifier. By pressing only one touch switch it can trace missing signals, distinguish between good and jittery (VCR sourced) signals, and identify the presence of good signals. Whenever a video signal is missing, because of bad connections, cable breaks or faulty sources, the Video Tester is all you need.

5.1Getting to Know Your 123V

The KRAMER 123V, one of the KRAMER TOOLS, is a high quality, state-of- the art Differential Video Line Amplifier designed for studios, retail outlets, showrooms and other demanding applications. The 123V splits a single input source into three identical outputs while almost completely isolating the input from the outputs. The 123V uses special differential amplifying circuitry, eliminating noise and hum problems commonly found in long video lines. The 123V uses an external 12VDC power source, and is therefore suitable for fieldwork as well. The machine has trimmers for easy adjustment of output video levels and cable equalization.
