Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups1 that are clearly defined by function.
Overview 3 Overview The Kramer 123Vxl Differential Video Line Amplifier is a highperformance line amplifier for composite or SDI video signals. It splits an input source to 3 identical outputs and includes controls and circuitry to compensate for signal losses and noise inherent in long cable runs.
Overview 3.1 Quick Start This quick start chart summarizes the basic setup and operation steps.

Connecting the 123Vxl Differential Video Line Amplifier 5 Connecting the 123Vxl Differential Video Line Amplifier To connect the 123Vxl, as the example in Figure 2 illustrates, do the following: 1. Connect the video source (for example, a video player) to the CV IN BNC connector. 2. Connect the CV OUT BNC connectors1—OUT 1, OUT 2 and OUT 3—to the appropriate video acceptors (for example, video display 1, video display 2, and video display 3). 3.
Connecting Differential Video Line Amplifier Units 6 Connecting Differential Video Line Amplifier Units You can connect up to five 123Vxl Differential Video Line Amplifier units, to provide up to 15 outputs, as Figure 3 illustrates. To connect up to five 123Vxl Differential Video Line Amplifier units: 1. Connect the video source to the CV IN BNC connector on the first unit. 2. Connect the LOOP BNC connector on each unit to the CV IN BNC connector on the next unit in the line, respectively1. 3.
