1. INTRODUCTION 1.1 Congratulations on your purchase of this Kramer Electronics amplifier. Since 1981 Kramer has been dedicated to the development and manufacture of high quality video/audio equipment. The Kramer line has become an integral part of many of the best production and presentation facilities around the world. In recent years, Kramer has redesigned and upgraded most of the line, making the best even better.

3. HOW DO I GET STARTED? The fastest way to get started is to take your time and do everything right the first time. Taking 15 minutes to read the manual may save you a few hours later. You don’t even have to read the whole manual. If the section doesn’t apply to you, you don’t have to spend your time reading it. 4. UNPACKING AND CONTENTS The items contained in your Kramer VM amplifier package are listed below.
VS-4E - (A precision mechanical 4x4 video/audio switcher) Several video/audio sources may be connected to its inputs for switching. The machine may be used in every application where easy and fast video and audio source selection is needed and for high isolation between inputs. All unselected inputs are internally terminated with 75-Ohm resistors. The VS-4E switches video, SDI and any other high frequency signals. The VS-4E is housed in a small enclosure, occupying very little desk space.
5. VM SERIES AMPLIFIERS This section describes all the controls and connections of your amplifier. Understanding the controls and connections helps you realize its full power. 5.1 Getting To Know Your VM-80V The Kramer VM-80V is a broadcast quality distribution amplifier designed primarily for composite video signals on BNC connectors. Using a simple rear panel switch, it can be configured either as a single 1:8 DA, or as two separate 1:4s.

5.2 Getting To Know Your VM-10AN Amplifier The Kramer VM-10AN is a compact, high quality 1:10 distribution amplifier using BNC connectors for composite video, and RCA connectors for stereo audio signals. It accepts one set of inputs, provides correct buffering and isolation, and distributes it to up to ten identical outputs designed to drive monitors, projectors, and other receiving devices. Bandwidth exceeding 70MHz ensures transparent performance with typical video and audio sources.
7. CONNECTING TO VIDEO DEVICES Video sources and output devices (such as amplifiers or recorders) may be connected to the amplifier through the BNC connectors located at the back of the machine. Please keep in mind that the output signal format must match that of the input signal format. 8. CONNECTING TO AUDIO DEVICES Audio sources and output devices (such as amplifiers or recorders) may be connected to the amplifier through the RCA type connectors (VM-10AN) located at the back of the machines. 9.
9.5 Operating the VM-80V Connect a cable from the video sources to the input sockets of the VM-80V. If a 1:8 operation is needed, press the rear button marked 1:8. If looping is needed, release the rear termination switch. If looping is not needed, press the switch in to the 75Ohm position. If 1:8 operation is selected, one of the termination switches should always be in "Hi-Z" state (released) and the other according to looping requirements. Connect up to 8 acceptors to the OUTPUT sockets.
11.1 Power And Indicators Problem No Power Remedy 1. Confirm that the rocker switch is in the “ ON” position, and that the light is illuminated. 2. Confirm that power connections are secured at the amplifier and at the receptacle. Make sure the receptacle is active, outputting the proper mains voltage.
11.3 Video Signal (VM-80V, VM-10AN) Problem No video at the output device, regardless of input selected Video level is too high or too low Noise bars "roll" up or down in the output image or: Low frequency hum in the output signal Remedy 1. Confirm that your sources and output device are turned on and connected properly. Video signals connected to the input of your amplifier should be of an identical signal format at the output of your source.
