Precautions Safety Instructions • English This symbol is intended to alert the user of important operating and maintenance (servicing) instructions in the literature provided with the equipment. This symbol is intended to alert the user of the presence of uninsulated dangerous voltage within the product's enclosure that may present a risk of electric shock. Caution Read Instructions • Read and understand all safety and operating instructions before using the equipment.
The IN3252HR is an ultrahigh resolution RGBHV video distribution amplifier (DA) with gain and peaking controls. It accepts RGBHV, RGBS, RGsB, RsGsBs, component video, S-video, as well as high resolution monochrome video and composite video baseband signals, and distributes the signals to two separately buffered outputs and one passive loop-through. The DA is powered by an external power supply, which is included with the unit.
IN3252HR Installation The IN3252HR can be placed on a desktop or shelf, or mounted in a convenient location using optional mounting brackets (IN9128). 1. Turn all equipment off and ensure that the source device, the DA, and the output devices have been disconnected from the power source. 2. Place or install the unit in the desired location. 3. Connect the video signal source (input) device to the input connector. 4. Connect the output devices to the output connectors. 5.
Peaking control — Rotate to adjust the amount of high frequency boost added to the video signals to compensate for long cable runs. R G B H/S V Input coupling jumpers (J1, J4, and J6) To insure the best picture quality, inputs are DC coupled as a factory default. If the source device has a high DC offset that causes picture distortion and/or instability, change the jumpers to AC coupling.
IN3252HR Without an oscilloscope 1. Feed a grayscale signal from an Extron VTG 300/400 or other A/V test generator to the input of the IN3252HR DA. 2. Adjust the green gain control potentiometer until the picture from the display device appears to have the correct brightness and contrast. 3. Adjust the red and blue potentiometers until the grayscale picture appears to be gray only; no color is present. 4.
