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 Format interface package are listed below.
5 FORMAT INTERFACES 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. 5.1 Getting to Know Your FC-10 The KRAMER FC-10 Composite-YC Transcoder is designed to interface between the two popular video formats: Composite Video and YC (Super-Video).
5.2 Getting to Know Your FC-19 The KRAMER FC-19 is an industrial level RGB Decoder, which converts both Composite Video and Super-Video to their RGB components. Front/Rear panel features of the FC-19 are described in Figure 2 and Table 3. NOTE For operation instructions refer to section 9. Figure 2: FC-19 Front/Rear Panel Features Table 3: FC-19 Front/Rear Panel Features No. Feature Function Illuminated switch supplies power to the unit. 1. Power Switch 2.
5.3 Getting to Know Your FC-4041C The KRAMER FC-4041C is a full broadcast, state-of-the-art Genlock RGB/Component to Composite Video/YC Encoder designed for studio and other demanding applications. The FC4041C encodes RGBS or Component Y, R-Y and B-Y signals to Composite Video and SuperVideo signals. All inputs are looped through with termination switches, allowing for parallel connection to other RGBS/Component acceptors.
5.4 Getting to Know Your FC-4042 The KRAMER FC-4042 RGB-Component Transcoder interfaces between the two most widely used professional video formats: Component Video (Y, R-Y, B-Y) and RGBS. In many video studios and production centers there is a need to convert from one format to the other, and the Kramer FC-4042 is the perfect choice as it operates simultaneously in both directions. Front/Rear panel features of the FC-4042 are described in Figure 4 and Table 5.
5.5 Getting to Know Your FC-4043 The KRAMER FC-4043 CV/YC - Component Transcoder interfaces between Composite video and Y/C to the most widely used professional video format - Component Video (Y, R-Y, B-Y) bi-directionally. In many video studios and production centers there is a need to convert from one format to the other, and the Kramer FC-4043 is the perfect choice as it operates in the most common standards - PAL, SECAM and NTSC (both) – and bi-directionally.
5.6 Getting to Know Your FC-4044 The KRAMER FC-4044 Multistandard Decoder interfaces from Composite video and Y/C to the most widely used professional video formats - Component Video (Y, R-Y, B-Y) and RGBS. In many video studios and production centers there is a need to convert from one format to the other and the KRAMER FC-4044 is the perfect choice as it operates in the most common standards PAL, SECAM and NTSC (both). Decoding is microprocessor controlled via the internal I2C bus.
5.7 Getting to Know Your FC-4208 The KRAMER FC-4208 Balanced/Unbalanced Audio Transcoder is a bi-directional, versatile tool, converting between the two most commonly used audio standards. The machine allows gain or attenuation while transcoding, to compensate for the 14dB change between IHF audio levels and the newly adopted, balanced DAT input levels. Very low noise and distortion components are used throughout the machine.
6 6.1 INSTALLATION Rack Mounting The FC-19, FC-4041C, FC-4042, FC-4043, FC-4044 and FC-4208 may be rackmounted in a standard 19” (1U) EIA rack, and include rack “ears” at the ends of the front panel. To mount them, 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 FC-10 can be rack mounted using a special adapter (see section 4.1). These devices do not require any specific spacing for ventilation above or below the unit.
9.5 Audio Level Control (FC-4208 only) A balanced audio signal is made of two antiphase signals, traveling on two wires (sometimes with a third - a ground reference / shield wire). A balanced signal achieves better signal-to-noise ratio, and is more immune to noise and interference. On the receiving end there is a differential amplifier, which amplifies only the difference between the antiphase signals, thus canceling noise which is picked up along the way and which is common mode.
10.2 Using PC Graphics in YC Production Some scan converters, which convert VGA/XGA graphics to video, generate only a composite video signal. The FC-10 converts composite video signal to s-Video (YC), thus enabling usage of computer generated graphics in professional YC productions, as shown in Figure 9. Perform the following steps (as necessary): 1. Connect a composite video source to the CV IN BNC connector of the FC-10 2. Connect an YC acceptor to the YC OUT 4P connector of the FC-10. 3.
Figure 10: Typical PC/Presentation Product Connections 10.4 Integrating a Composite/RGB source Into a Composite/YC Switcher 31B It is sometimes necessary for pre-edit purposes, to switch a component video source alongside composite or Y/C sources. Some but not all of the component video sources include a composite or a Y/C output. In order to perform the above-mentioned task, a video encoder is needed in order to convert either YUV or RGB signals to composite and Y/C signals, as shown in Figure 11.
Figure 11: Integrating a Component/RGB Source Into a Composite/YC Switcher 10.5 Audio Format Conversion 32B Professional audio usually requires balanced audio signals that are less prone to interference due to the differential signal setup. When using unbalanced and balanced signals at the same setup, amplification or attenuation is needed to match the levels. An Audio Transcoder (FC-4208 in this case) can be used for this purpose and for signal conversion as well, as shown in Figure 12.
Figure 12: Audio Format Conversion 11 TAKING CARE OF YOUR MACHINE 10B Do not locate your machine in an environment where it is susceptible to dust or moisture. Both of these may damage the electronics, and cause erratic operation or failure. Do not locate your machine where temperature and humidity may be excessive. Doing so may also damage the electronics, and cause erratic operation or failure of your machine. Do not clean your machine with abrasives or strong cleaners.
12 TROUBLESHOOTING NOTES 1. 2. 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 do not result in satisfactory operation, please consult your KRAMER Dealer. 12.1 Power and Indicators Problem No Power Remedy 1. 2.
Figure 13: FC-10 Fuse Location 12.2 Video Signal Problem No video at the output device Remedy 1. 2. 3. Video level is too high or too dim. 1. 2. 3. 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.
Video Signal (continued) Problem Noise bars are "rolling" up or down in the output image or: Remedy Hum bars (ground loop) are caused by a difference in the ground potential of any two or more devices connected to your signal path. This difference is compensated by passing that voltage difference through any available interconnection, including your video cables.
