Abstract
The invention provides an addressing broadcast terminal controller with a forced switching function. In the invention, a mechanical switch for forcibly connecting a speaker is installed on an addressing broadcast terminal controller; in the amplifying activities (such as college entrance examination) with relatively high safety requirement, an emergency switch on the terminal controller is pressed to directly force connection between a broadcast line at the front end and the speaker, and the amplification is not influenced by the fault of the addressing function.
Description
Technical field
The present invention relates to Public Address system, relate in particular to the addressable constant-voltage Public Address system.
Background technology
Public broadcasting is widely used in public places such as school, square, hospital, plant area, army, airport, residential quarters, and the loud speaker of public broadcasting all can be installed in each classroom of school, each room of office block etc.And the function of existing Public Address system also from strength to strength, like addressable broadcast of each independent loud speaker being carried out from the broadcast main control chamber etc.
The control mode of existing constant-voltage addressable broadcast does, loads a terminal control unit at the front end of loud speaker, accepts the control of front end studio and opens or closes the output channel to loud speaker.And the demand for security that amplifies in some particular importance occasions is high especially; Like college entrance examination, Leading Speaches etc.; Do not allow in the process that amplifies, to exist any fault maybe, numerous like this terminal control units just becomes the fault hidden one by one maybe point, has reduced broadcast safe property.
Therefore, provide the higher constant-voltage addressable broadcast equipment of a cover fail safe to seem anxious for urgent.
Summary of the invention
In sum, the invention provides a kind of addressable broadcast terminal control unit with forced cutting function.
For realizing above-mentioned purpose; The present invention has installed a mechanical switch that is used to force to connect loud speaker on the addressable broadcast terminal control unit; To safety requirements during than the higher activity that amplifies (like college entrance examination) press being connected between program circuit that emergency switch on the terminal control unit can directly force to connect front end and the loud speaker, and guarantee can not influence to amplify because of the fault of addressing function.

Embodiment
As shown in the figure; The present invention provides a kind of addressable broadcast terminal control unit with forced cutting function to comprise a mechanical switch C who is used to force to connect loud speaker; The position of switch C is installed in the addressable broadcasting control terminal B; Be communicated with the audio power signal of front end public broadcasting control room A output and the circuit of loud speaker, key is to skip the control section of addressable broadcasting control terminal B, when pressing switch C; The audio power signal that can force to connect front end public broadcasting control room A output is connected with the circuit of loud speaker, reaches the purpose of forcing broadcast.
Claims (1)
1. be with the addressable broadcast terminal control unit of forced cutting function, it is characterized by: the addressable broadcast terminal control unit of described band forced cutting function comprises a mechanical switch that is used to force to connect loud speaker.
