The apparatus is designed for recording video programs on several VCRs simultaneously. This video splitter - active, and excludes the mutual influence of VCRs at each other.
Matching modules made on chips BA7604N. They are designed for switching video signals to the interface units and VCRs TVs at a low frequency. Each chip contains two identical amplifier, designed for 75-Ohm-ing the load. With this load they have unity gain. The inputs of the amplifiers is sufficiently high resistance that allows you to one 75-Ohm output, such as a VCR to connect a virtually unlimited number of such modules.
Video and audio signals received through the connectors "Input. video" and "BX. audio" respectively. These jacks are connected to the inputs of all chips. Weekend resistance output modules - 75 Ohm. Nominal input level and the output video signals - 1, frequency response is linear in the range of 0.05...6000 kHz (with the unevenness of 1 dB).
Eats videoresolution from the source voltage of 5 V using a current of about 1 A.
