CIRCUIT ARRANGEMENT FOR TRANSMISSION OF LOCAL BROADCASTING STATION SIGNAL THROUGH DISTRIBUTION NETWORK OF CABLE TELEVISION

摘要

The present invention is characterized in that output of an input microphone (9), representing a part of an input stage circuitry is connected to a low-frequency signal modulator (3) with a pilot frequency for conversion of an output audio signal of a public address system to a modulated high-frequency signal with a pilot frequency. Its input is further connected to the input stage circuitry source (1) and at the same time to a module (2) of controlled discharge of the input stage circuitry. Said modulator (3) is connected to a main station (4) of television cable distribution system (TKR), where signal conditioning and transmission thereof in the television cable distribution system network. Said main station (4) output is then connected within the TKR network to at least one TKR amplifier (5). A module (6) for controlled charging of a power amplifier stage, representing a part of the power amplifier stage circuit i.e. a user's station is connected to said TKR amplifier (5) output. Th
