On the other hand, the present invention is not limited only to the above-described exemplary embodiments, it can be carried out in various ways without departing from the maintenance of the present invention in a variety of improvements, modifications, substitutions or additions of ordinary skill in the art Anyone who has a can understand it easily. If such improvement, change, substitution or addition is carried out within the scope of the following claims, the technical idea should also be regarded as belonging to the present invention.

Accordingly, in the present invention implemented as described above, when a sound source is generated through each microphone 101, CDP 102, deck 103, tuner 104, VTR 105, the sound source is electronic free. The input signal to the amplifier 110 is adjusted (amplified), and is adjusted (amplified) by a volume control volume of a separately connected computer or a front panel (not shown), and the adjusted (amplified) signal is then converted into the program converter 120. Will be printed.

At this time, the electronic preamplifier 110 simultaneously executes the preamplifier function installed in the existing analog equipment, and installs the A / D converters 111 and 112 at the audio input and the audio output, respectively. Detects and converts an input audio signal and an output audio signal and transfers the same to the first CPU 13.

At the same time, the first CPU 113 is used because an input volume and an output volume are used as electronic volumes, and an audio bus and an electronic switch are used. It can be easily controlled through.

Accordingly, the electronic preamplifier 110 may control the remote control, which was not possible in the existing analog equipment, through the UART 114, and program the first preliminary CPU 113 to operate in conjunction with the existing fire method. By using it for public address broadcasting, the operation of the public address broadcast is made more efficient.

In addition, since the first contact converter 115 and the first IR converter 116 are additionally connected to the first CPU 113, the first contact converter 115 and the first IR converter 116 may be flexibly coped with various situations that may occur in the public address broadcast. .

When the signal output through the electronic preamplifier 110 is input to the program converter 120, the program converter 120 uses the emergency 121, the timer 122, the RM1 123, and the RM2 124. Broadcast priority is determined in the order of BGM 125.

In this case, the sound sources whose broadcasting priority is determined are output from the program converter 120 and input to the sound power amplifier (POWER AMP) 130, and are then converted into a signal having a sufficiently large power.

The signal converted by the power amplifier 130 needs to be divided into detailed regions to be broadcasted. This is divided into relay regions (RELAY GROUP) 140 to each region to drive a relay in a desired region and then passes through the terminal plate 160. The sound source is transmitted to each region through the speaker 170, and the broadcasting priority can be changed according to each characteristic.

It is possible to prevent the broadcasting from being cut off.

As described above, the electronic matrix 150 simultaneously performs the mechanical contact operation of the matrix installed in the existing analog equipment, converts the mechanical contact into a digital signal by the third A / D converter 151, and then converts the mechanical contact into a digital signal. The CPU 153 transmits the result.

In this case, the signal transmitted through the third A / D converter 151 is analyzed by the second CPU 153, and the analyzed signal outputs a digital signal to the outside through the second UART 154. The digital signal transmitted through the second UART 154 transmits the signal to a computer or other digital equipment, which can use the digital signal in various forms.

In addition, a digital signal output from an external computer or other digital equipment is transmitted to the second CPU 153 through the second UART 154, and the transmitted digital signal is transmitted to the second CPU 153. The signal is analyzed and then converted into an analog signal by the D / A converter 152 to drive existing mechanical contacts.

Accordingly, it is possible to analyze the mechanical contact signal, which is a control signal for the existing public address system, and to control the mechanical contact signal, and to use the digital system of public address system while using other equipment such as analog equipment. It can be realized.

In addition, since the second contact converter 155 and the second IR converter 156 are additionally connected to the second CPU 153, the second contact converter 155 and the second IR converter 156 may be flexibly coped with various situations that may occur in the public address broadcast. .

For example, the second IR converter 156 may be used to drive equipment using another remote controller, and the second contact converter 155 may also drive other equipment not using an IR method. will be.

As described above, the control signals are commonly transmitted to the electronic matrix 150, the electronic matrix 150 converts the contact signal into a communication signal to transfer all of these situations to the computer, all of the above situations The computer can receive the current status graphically so that the user can directly check the current broadcast status.

In addition, when the computer directly transmits a command (control) to the electronic matrix 150 through communication, the electronic matrix 150 converts a communication signal into a contact signal to drive broadcast devices that are existing analog equipment. will be.

As such, even when the computer cannot be used due to a computer abnormality or a virus, the electronic matrix 150 can use the existing contact method as it is, so that manual operation of the existing analog method is easy and thus the overall broadcast operation can be performed. The dual security scheme is enabled, and even if an error occurs in an electronic component such as a microprocessor installed in the electronic matrix 150, even if an error occurs, the existing operating method for analog broadcasting can be continuously used.

The volume can be changed by external communication, and the analog PA system can be operated more efficiently through the analog method even when an internal processor or an external computer is connected. What can be operated by the system to be.

Following this, the present invention realizes automated broadcasting by making the best use of the analog broadcasting apparatus, thereby enabling digitalization of the broadcasting at a minimum cost, and at the same time, a broadcasting accident that may occur when a semiconductor device, which is an electronic component such as a microprocessor, malfunctions. It is possible to prevent stable and accurate broadcasting is possible.
