Even if AC / DC is used, DC + 24V And a priority is given to the operation of other external inputs by incorporating a broadcast function first.

In an audio configuration, an audio device in charge of amplification is called an amplifier or amplifier, and serves to amplify a small electrical signal into a large electrical signal. Therefore, the amplifier is the basis of all electronic circuits, and electronics also assigns an important weight to the analysis and design of the amplifier.

In audio equipment, amplifiers are divided into preamplifiers (pre amplifiers) and power amplifiers (power amplifiers). When these two amplifiers are in one device, they are called integrated amplifiers.

And if there is tuner in the integrated amplifier, it is called receiver.

The output of the audio device is once amplified in the preamplifier and added to other controls and sent to the power amplifier. In a power amplifier, a large amount of power is sent to the speaker to simultaneously amplify the voltage and current of the electrical signal. Audio quality depends a lot on the circuitry used in the amplifier, the quality of the material, and the type of amplifier.

Other devices may intervene between the two types of amplifiers described above, such as equalizers, dynamic expanders, and surround processors.

In particular, a power amplifier (power amplifier) is equipped with a DC 24V input terminal in case of a power failure so that it is suitable for emergency broadcasting.

Equalizers have been around for a long time since they emerged as the new leaders in audio systems. In recent years, its use is more and more dozens of types, boasting excellent in terms of performance and design. These products were a kind of accessory among acoustic devices only a few years ago, but they are now firmly established as part of the audio system.

In general, in the case of an audio device, an equalizer amplifier is a device having a function of increasing or decreasing the amplification level from 5 to 32 frequencies between 16Hz and 32kHz, which is low in the range.

In other words, the equalizer is capable of making sounds according to the tastes of the listeners.

The audio mixer (AUDIO MIXER), sound source playback device (DIGITAL TUNER, CASSETTE DECK, CD PLAYER) And so on.

Broadcasting equipment can be used by using an integrated type according to the specific characteristics and conditions of the site, or by assembling the above modules (panels) in an enemy combination and assembling them according to conditions.

The above example illustrates an example of a typical configuration, and various devices may be referred to as various names.

In the description of the present invention, a part of the coupling relationship between the respective module components is not explained in detail, but the coupling relationship system is commonly used. And the coupling relation between each module and each component is described.

In the following description of the present invention, a broadcasting apparatus system using a module having a basic configuration is referred to as a broadcasting apparatus because of the characteristics of a rack-type broadcasting apparatus in which each module is used in various forms in accordance with the circumstances of the site, A description related to the features of the invention among the broadcasting apparatus components will be specifically described.

Also, a set of modules required for broadcasting an emergency broadcast in the configuration of a broadcasting apparatus is referred to as an emergency broadcasting module.

Due to the nature of each situation, emergency broadcasting modules may be different, so that the detail modules can not be limited.

For example, an intercom 600 series rack system of the domestic company can be applied to an emergency module (model name ECS-616) having overall control functions related to emergency broadcasting, but it is possible to use an emergency switch module, a matrix module, a relay group module, a speaker selector module , And terminal board modules may be mounted in each rack.

For example, in the configuration of an A / V (Audio / Visual) device, the audio part constitutes a speaker, a microphone, an audio mixer, a power amplifier, a power supply, a sound reproduction device (DIGITAL TUNER, CASSETTE DECK, CD PLAYER) Lt; / RTI >

The main control unit is a main control unit for program control of the entire A / V equipment. It can control remote control or simultaneous control by the control server separately. The power supply unit supplies 220V commercial power and DC 48V at power failure, An acoustic signal, and an electronic sound signal generated through a sound source reproducing apparatus are tuned in an audio mixer, amplified through a power amplifier, and broadcast through a speaker.

For example, a public address rack configuration may include a speaker, a microphone, a power amplifier, a preamplifier, an emergency broadcast device, a tuning device, a power supply device, a sound reproduction device (DIGITAL TUNER, CASSETTE DECK, CD PLAYER) and main controller,

The main control unit is a main control unit that controls the whole broadcasting system. It can control remote control or simultaneous control by control server separately. The power supply unit supplies 220V commercial power and DC 48V when power failure. The generated electroacoustic signal is amplified through a preamplifier and a tuning device, amplified by a power amplifier, and broadcasted through a speaker. When a fire signal is received, an emergency broadcast occurs through an emergency broadcast device.

When two microphones are arranged close to one original sound or center original sound when the original sound is received through the microphone, the phase of the original sound may be resonated. That is, the phase of the sound is superimposed so that some phases disappear and some phases merge. Especially, when two microphones can not be installed at a sufficient distance from the original sound source, they are generated.
