The TVCA-4/1200 Video Signal Amplifier is designed to amplify four video signals transmitted via coaxial cables, allowing video transmission over distances up to 1200 meters. The adjustment knobs enable simultaneous control of both amplitude (gain) and frequency response (correction). As the gain increases, the correction value also increases proportionally. The amplifier should be installed at the end of the transmission line, near the monitors. It is recommended to protect the equipment from surges caused by lightning discharges using surge arresters (e.g., OPV-4).
