3 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 a 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 Line Amplifier package are listed below. Please save the original box and packaging materials for possible future transportation and shipment. �� Line Amplifier �� AC power cable (where applicable) or 12VDC power supply �� User Manual �� K ...

4 5 LINE AMPLIFIERS This section describes all the controls and connections of your line amplifier. Understanding the controls and connections helps you realize the full power of your line amplifier. 5.1 Getting to Know Your VM-9S Amplifier The KRAMER VM-9S Video/Audio Line Amplifier is a high quality amplifier which compensates for video and audio signal losses when long cables are used. In any video/audio setup requiring considerable distances between video/audio source and acceptors, signal loss and thus depreciation in the quality of both picture and sound is a real problem. To prevent this phenomenon, a VM-9S amplifier is ...

5 5.2 Getting to Know Your VM-9YC Amplifier The KRAMER VM-9YC Y/C Line amplifier is a high quality amplifier which compensates for Y (Luma) and C (Chroma) signal losses when long cables are used. In any video setup requiring considerable distances between video source and acceptors, signal loss and thus depreciation in the quality of picture-becomes a real problem. The VM-9YC allows the user to compensate for cable losses by changing the level of the Y signal and its frequency response, as well as and the level of the C signal and its phase. The machine has a looping input with termination switch and two outputs, thus serving a ...

6 5.3 Getting to Know Your 103YC line Amplifier The Kramer 103YC is a high performance line amplifier which combines the functions of a distribution amplifier and line driver. It accepts a single S-video (Y/C) input and provides three identical buffered outputs that are affected by gain and equalization controls located on the top panel. The gain and equalization controls are designed to compensate for signal loss inherent in long cable runs. Separate overall gain controls for Y (Luma) and C (Chroma) are provided, and the EQ. control boosts the upper frequencies of the Y component most susceptible to loss. Bandwidth exceeding ...

7 5.4 Getting to Know Your 104L line Amplifier The 104L is a high performance line amplifier, which combines the functions of a distribution amplifier and line driver. It accepts a single composite video input and provides four identical buffered outputs, which are affected by gain and equalization controls located on the top panel. The gain and equalization controls are designed to compensate for signal loss inherent in long cable runs. The gain control adjusts the overall signal level, and the EQ. control boosts the upper frequencies most susceptible to loss. Bandwidth of 430MHz ensures that the 104L remains transparent ev ...

8 6 INSTALLATION 6.1 Rack/Table Mounting The VM-9S and the VM-9YC amplifiers may be rack mounted in a standard 19” (1U) EIA rack assembly using special adapters (see section 4.1 "mechanical adapters"). These adapters allow 1or 2 machines to be installed on each adapter, depending on the model. The 103YC and the 104L can be table mounted using the two brackets enclosed in the box or installed in rack adapters that can accommodate 3 or 8 machines. To mount any of the amplifiers into the rack, follow the instructions in the installation guide enclosed with the adapter. These devices do not require any specific spacing above or b ...

9 9.3 C Phase Control (VM-9YC only) When long cables are used in any video setup, phase shift occurs due to stray capacitance and inductance as well as for other cable related reasons, resulting in signal distortion and thus depreciation in the quality of picture. The colors may be wrong and the color information may be delayed more than the black and white information, causing a "misprinted" image. The inputs and the outputs of the machine in use should match perfectly to the cables used in order to avoid all sorts of unwanted phenomena, which deteriorate the final image. The cables leading to and from the amplifier should be ...

10 incoming video signal, an oscilloscope should be connected to amplifier’s output and the Gain/Level trimmer/knob adjusted until a satisfactory sync level and hence proper picture are achieved. 9.9 Typical Line Amplifier Setup Figure 4 illustrates a typical setup of the line amplifiers described in this manual. Perform the following steps: 1) Connect the output of the video source to the inputs of a line amplifier (VM-9S in the example). Always locate the line amplifier as close as possible to the video source. 2) Connect the output of the line amplifier via the long cable to the input of the DA. 3) Use the looping option ...

11 10 TAKING CARE OF YOUR LINE AMPLIFIER Do not locate your line amplifier in an environment where it is susceptible to dust or moisture. These may damage the electronics, and cause erratic operation or failure. Do not locate your line amplifier where temperature and humidity may be excessive. Do not clean your line amplifier with abrasives or strong cleaners. Doing so may remove or damage the finish, or may allow moisture to build up. Take care not to allow dust or particles to build up inside unused or open connectors. 11 TROUBLESHOOTING NOTES 1. Please note that if the output signal is disturbed or interrupted by very strong ...

12 11.2 Video Signal Problem Remedy No video at the output device 1. Confirm that your source and output devices are powered on and connected properly. The input of your amplifier should be of an identical signal format at the output of your source. Signals at the output of your amplifier should be of an identical signal format as at the input of your display. 2. Confirm that any other device in the signal path has the proper input and/or output selected. 3. Use the Video Tester to test the video path leading to/from your amplifier (see section 4.1" Video Tester") Video level is too high or too dim. 1. Verify that the lines are ...
