Whether it is a large enterprise, a small enterprise or a government agency, the conference room cannot lack audio equipment. According to the function and size of the conference room, there are different equipment. Other products, these conference room audio equipment have different functions and prices. The following is a brief introduction Several kinds of audio equipment commonly used in conference rooms.

The microphone is indispensable in the conference room and is an important sound collection device. You can use a microphone to collect participants' voices and broadcast them to speakers to amplify the sound. There are many types of microphones, from general meeting room applications to desktop conference microphones.

Microphones are commonly used devices in conference room applications, also known as goose microphones. The microphones are usually opened hand in hand. All microphones are connected in series to the conference host, which sends the audio to mixers, power amplifiers, telephone couplers, etc.

There are many types and brands of microphones. You can also use wireless microphones, omnidirectional microphones, and ceiling microphones for conferencing applications. Their brands and prices are also very large, ranging from tens of yuan to several thousand yuan, and users can choose reasonably priced microphone products according to the project budget. conference room audio

Amplifiers are easy to understand. The amplifier amplifies the sound collected by the microphone and sends it to the speakers for distribution in the venue. It also achieved the purpose of deploying audio equipment in the conference room. I can't hear my speech clearly in the large conference room. I want to amplify it through sound equipment.

There are also many brands of power amplifier products for conference room audio equipment at various price points. The connection method is relatively simple. The audio source that needs to be amplified can be connected to the audio input interface of the amplifier. These audio sources can come from microphones, music players, video conferences, and more. Connect audio input and speakers.

Conference room audio equipment Speaker is a common audio equipment, we usually see more computer audio. The speakers used in the conference room are similar, but the sound of the conference room is amplified, and the selection of speakers is various. Brand and price are just one factor. Choose the right power supply product according to the size of the conference room. You can also use floor standing speakers or ceiling speakers depending on how you deploy. Configure the speakers according to the overall design requirements of the conference room.

Noise control solution for functional sound reinforcement system

Multifunctional audio equipment sound reinforcement system, the main consideration is that the sound reinforcement system conveys clear, easy-to-understand, clear and warm music without noise interference. At the same time, it is necessary to ensure that it has an excellent frequency response width and a small distortion response under the condition of a uniform sound field. So the choice of speaker system is very important.

In the multifunctional audio equipment system of the functional audio solution, all signals except the target signal are noise, but the signal and the noise exist at the same time and complement each other. When the signal is in different places, it definitely creates noise, but the noise doesn't have to be caused by the different places. To remove noise in an acoustic amplification system, let's first look at the relationship between ground and signal:

Grounding and signaling are often referred to as references and topics. The signal ground is the reference of the signal, and the ground usually refers to the connection with the ground, but in the sound reinforcement system, it has nothing to do with the ground. is the reference set in the system, and grounding is essential. It looks simple, but it's actually quite complicated. According to its different functions, it can be divided into functional grounding and protective grounding. Functional ground includes the following four types.

(1) Working grounding, also known as system grounding, is to ensure the normal operation of the system, prevent system oscillation, and ensure the reliability of equipment in the system. Grounding is usually required at the appropriate location where the multifunction audio equipment unit operates. As a common 220V power supply, the ground wire is the neutral point of the transformer.

(2) To obtain a stable reference potential, set the logic ground, also known as DC neutral.

(3) The shield ground is a ground installed to prevent the influence of electromagnetic induction on the system. It is the complex grounding of all grounding systems because it prevents others from interfering with each other at the same time. The higher the interference frequency, the denser the metal mesh used for shielding, otherwise the effect will not be achieved.
