EZ-VDA3B

Video Distribution Amplifier

TYPICAL APPLICATION

The EZ-VDA3B is a composite video distribution amplifier with three outputs. The input and outputs are all 75 Ωon BNC connectors.

If the outputs are connected to long coaxial cables (typically 100 to 1000 feet) the front-panel gain and equalization trimmers

may be adjusted to restore picture clarity. The wide amplifier bandwidth supports high quality video distribution. The EZ-VDA3B

is used in stores, houses of worship, restaurants, clubs, security and commercial A/V systems.
