FSR, Inc CVD-144
Composite Video Bridging Distribution Amplifier


FSR introduces the CVD - 144, the world's first configurable Distribution Amplifier (D/A). Four independent 1 x 4 D/A's are integrated within the 1RU chassis. What makes the CVD-144 unique is the ability to bridge adjacent 1x4 blocks to make a larger D/A.

In its default configuration, the CVD-144's four 1x4 D/A's operate independently. By simply flipping the bridge switches, adjacent 1x4 D/A's are bridged together and the input of the first block is sent to all of the bridged outputs allowing many different configurations to suit your signal distribution needs.

Possible configurations include: four 1x4 D/A's; one 1x8, and two 1 x 4 D/A's; two 1x8 D/A's; one 1x12, and one 1x4 D/A's; and one 1x16 D/A. To insure the highest possible signal quality, all outputs are fully buffered, and the measured bandwidth, from input to any output, is greater than 350MHz with a flat signal response.

The CVD-144's extended bandwidth makes it compatible with all analog video signals, including HDTV. In addition, each of the block's inputs may be used independently or in concert to distribute composite, component, and S-video. A universal power supply extends the CVD-144's compatibility to the world.
