The purpose of this circuit is to provide the distribution of analog video signals between several televisions without loss of intensity. An application would be in hotels or schools where the same CD player can generate signals for several televisions at the same time. The potentiometer P1 adjusts the gain of the operational amplifier and, therefore, the signal strength at the outputs. Both inputs and outputs must be shielded using appropriate cables. The primary winding of the transformer must be in accordance with the local network.
