When distributing video signals through medium and large facilities, the VEA-681 will provide hum removal and equalization for long cable runs of up to 1000 ft. The VEA-681 features 30 MHz bandwidth, differential input and continuously variable equalization for up to 300 meters (1000 ft) of Belden 8281 coaxial cable. Optionally, the equalizer can be customized to accommodate other cable types. The VEA is also suitable for use in analog component/composite and analog HDTV signal distribution.
