Key Features:

The Kramer VP-123 and VP-123V are high performance 1:3 distribution amplifiers for graphics and component video signals. Both machines use 5 BNC connectors for each output. The VP-123 uses 5 BNC connectors for the inputs, while the VP-123V uses a inchVGAinch - HD15F connector for the input. The VP-123/V have three high bandwidth analog channels - Red, Green and Blue that may be used, if needed, for other video formats - such as Composite, Y/C, Component etc. The two other channels are H Sync and V Sync channels which are digital / logic channels, and include special circuitry for sync reconstruction and shaping. In addition to a typical RGBHV application, the three analog channels can operate independently, allowing the machine to be used as three separate 1:3 DA's for composite video or other formats. Bandwidth of over 450MHz ensures that the VP-123/V remains transparent even in critical broadcast or high resolution applications. The machines are housed in a rugged, professional, rack mountable enclosure requiring only one vertical space in a standard 19inch rack, and are fed from a 12VDC source, making them ideal for fieldwork as well.
