1 INTRODUCTION Congratulations on your purchase of this Kramer Electronics Sync processor. 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.
Vertical sync, often referred to as the field sync (see Figure 2), is also a negatively directed set of pulses, found at the beginning of each video field (60 field/sec. in NTSC, 50 fields/sec. in PAL). Vertical sync is a more complicated signal than horizontal sync, which tells the monitor: “be prepared, a new field of data is coming”. Vertical sync also resides in the blanking area, and is not visible on the screen. Figure 2: Vertical Sync 1.1.
Another twist to this format is that in most cases the logic-level syncs are separated and run each in its own channel, but there are cases where the logic-level syncs come composite – joined together in the same mix of directions. In the digital world – SDI, DV, MPEG and other formats, the synchronization signals either travel in a special digital sync channel or, in most cases, are embedded in the digital signal.

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 Sync Processor package are listed below.
5 SYNC PROCESSORS This section describes all the controls and connections of your machine. Understanding the controls and connections helps you realize the full power of your machine. 5.
5.2 Getting to Know Your SG-7 Sync Transcoder The KRAMER SG-7 Universal Sync Transcoder interfaces between the widely used professional video sync formats - Composite sync, Horizontal sync, Vertical sync - Analog and TTL levels. In many video studios and professional applications there is a need to convert from one format to the other, and the KRAMER SG-7 is the perfect choice - as it operates simultaneously in all directions. Front/Rear panel features of the SG-7 are described in Figure 4 and Table 3.
5.3 Getting to Know Your SG-9 Video Black Burst Restorer The KRAMER SG-9 Video Black Burst Restorer replaces corrupted or missing horizontal and vertical syncs as well as color burst from a video signal with standard synchronization and color signals. In many cases the KRAMER SG-9 can replace or enhance a TBC operation. The SG-9 generates standard sync and color information from internal high quality, genlocked, sync and color generators.
5.4 Getting to Know Your SG-11 Sync to Green Adder/Stripper The KRAMER SG-11 Sync to Green Adder/Stripper interfaces between the two most widely used professional Component Video formats - RGB with Sync On Green and RGBS. In many video studios and production centers there is a need to convert from one format to the other and the KRAMER SG-11 is the perfect choice - as it operates simultaneously in both directions. Front/Rear panel features of the SG-11 are described in Figure 6 and Table 5.
5.5 Getting to Know Your SG-6003B Black Burst/Color Bar Generator The KRAMER SG-6003B is a broadcast level Black Burst/Color Bar Generator for video studio applications. The SG-6003B provides three identical Black Burst outputs, a color Subcarrier output, a Color Bar output and two 1 kHz, crystal stabilized audio outputs. State-of-the-art technology is used throughout the SG-6003B - crystal controlled sync and Chroma oscillators, accurate internal sync/Subcarrier genlock, both with long term stability.
6 6.1 INSTALLATION Rack Mounting The SG-7 and the SG-6003B can be rack mounted in a standard 19” (1U) EIA rack, and include rack “ears” at the ends of the front panel. To rack mount these machines, simply place the unit's ears against the rack rails of your rack, and insert standard screws through each of the four corner holes. The SG-6N, SG-9 and the SG-11 can be rack mounted using a special adapter (see section 4.1).
removed in the same way by performing proper clamping. To clamp the DC level to -1V or 0V select the desired level using the -1V/0V switch located on the machine's rear panel. 8 TAKING CARE OF YOUR PROCESSOR Do not locate your processor in an environment where it is susceptible to dust or moisture and temperature and humidity may be excessive. All of these may damage the electronics, and cause erratic operation or failure. Do not clean your processor with abrasives or strong cleaners.
9.2 Black Burst/Bar Generator Connections Figure 9 describes typical usage of a Black Burst/Bar Generator, where the SG-6003B functions as a test and alignment tool for the audio and video acceptors and can provide black or color reference bar for cameras that need a stable reference. A Subcarrier signal is also provided to a Chroma Keyer/Mixer for special effects operation.
Figure 10: Restoring Black Burst and Image Stability 9.4 Transcoding Various Sync Formats Transcoding between various video sync formats can be performed by the SG-7, as described in Figure 11. Perform the following steps (as necessary): 1) 2) 3) 4) 5) Connect a composite sync source to the C Sync In BNC connector of CHANNEL 1. If looping is not needed, switch the termination switch to "75ohm" position. Connect TTL level H & V syncs into the inputs of CHANNEL 2.

10 TROUBLESHOOTING 1. 2. NOTES Please note that if the output signal is disturbed or interrupted by very strong external electromagnetic interference, it should return and stabilize when such interference ends. If not, turn the power switch off and on again to reset the machine. If the following recommended actions still do not result in satisfactory operation, please consult your KRAMER Dealer. 10.1 Power and Indicators Problem No Power 1. 2. 1. 1. 2. 3.

Remedy Confirm that your source and output devices are powered on and connected properly. The input of your machine should be of an identical signal format at the output of your source. Signals at the output of your machine should be of an identical signal format as at the input of your display.
