Conference Audio Supplier
How to identify the sound quality of an audio system: the factor of quantity: quantity refers to the loudness of the sound. There is no loudness, the singer must be very difficult, how about the sound effect is good! Like cooking, the dishes are not cooked, how about the taste! The amount is not enough, in fact, objectively reflects the power problem of the audio system. Contact Us Therefore, sufficient power is required. Give the singer a sense of surrounding environment. Singing is more relaxing. Choose several elements of the sound system: the effect of the sound system; as the saying goes, it is difficult to adjust. The sound is the same as cooking, and the taste is different. The sound system should try to cater to the preferences of local consumers. The participating judges may have different opinions, as long as most of them agree.
The design of conference sound reinforcement system usually starts from the sound field, and then advances back to the power amplifier, sound processing system, mixer, and microphone and other sound sources. This step of design step by step backward is very inevitable. Because the sound field design is the basis to meet the system functions and sound effects, it involves dimmer power pack the selection of the speaker system, the sound supply scheme and the signal path. Only when the speaker system is determined can the calculation of the driving power of the power amplifier and the determination of the driving signal path be performed, and then the signal processing scheme and the selection of the mixer can be further determined according to the driving power distribution scheme.
The company’s main business: the sale of audio and video equipment such as professional audio, stage lighting, KTV audio, multimedia conference, public broadcasting, video conference, home theater, VOD song system, etc. And to undertake the indoor and outdoor lighting and sound engineering, KTV and club audio, multi-function hall audio, conference room audio, public broadcasting and other lighting and audio engineering design and construction.

The feedback suppressor of professional audio equipment. In the sound reinforcement system, if the volume of the microphone is greatly increased, the sound from the sound will be transmitted to the microphone. This phenomenon is acoustic feedback. The presence of acoustic feedback not only destroys the sound quality, but also limits the expansion volume of the microphone sound, so that the sound picked up by the microphone cannot be reproduced well; the deep acoustic feedback will also make the system signal too strong, which will burn the amplifier or sound (generally it is burned) Audio tweeter), causing losses. Therefore, once the sound feedback system appears sound feedback, we must find ways to stop it, otherwise, it will be endless.
Professional audio equipment improves loudness, compresses and limits the dynamic range of programs, which can suppress strong signals and enhance weak signals. Because the sound intensity felt by the human ear is the average sound level for a certain period of time, in the program with a lower average sound level, some high-level peak signals that occasionally appear do not sound like such peaks, But programs with higher average sound pressure levels are louder. The use of compressors has the following effects. After accessing the compressor, through its compression and limiting functions, it plays a protective role for the entire system. This is the main purpose of widely configuring compressors in theaters and dance halls.
Relying on reliable product quality and excellent after-sales service, Dongcheng Audio has many good partners in and outside the province. Now the company strictly abides by the customer-oriented management and continuously improves the product quality and service level.
Selection of digital wireless conference control system host. The BASETHINK digital wireless conference system is composed of a digital wireless conference control system host, a digital wireless conference unit, a digital wireless conference delegate unit, a power amplifier, a stereo, and desktop display equipment (such as a desktop intelligent terminal, liquid crystal display). , The role of sound reinforcement. The product uses digital wireless processing of audio signals and control signals without cumbersome wiring, built-in CPU multi-level error correction and encryption scrambling code, to prevent cross-frequency interference and anti-mobile phone electromagnetic interference.
Since entering the market, Fuyang Dongcheng Audio has cultivated a solid and well-trained engineering team through years of sales, design, construction, installation and commissioning of audio engineering and system integration, laying a good foundation for the company’s development. At the same time, the company has set up a special after-sales maintenance department. The technicians have rich maintenance experience. They are responsible for the maintenance of peripheral audio and video equipment such as amplifiers, speakers, mixers and other brands. While focusing on their customer service, they also provide different customer groups. Solved various difficulties and needs, won unanimous praise from customers and established a good brand awareness.
The selection of microphones in KTV audio equipment is very important. Early stage developers like to use professional microphones such as SHURE. Until recently, they realized the professional attributes of karaoke microphones. Karaoke microphones require the mesh head to be durable and resistant to wear and tear. The switch is durable and the lead is tough. This is a more basic requirement. What is more important is that the karaoke microphone needs to be less simple to feedback the whistle (flying mark), and the vocal should be specially optimized and enhanced to attenuate the surplus. Low frequency and ultra high frequency make the middle and high frequency of human voice more prominent, so-called simple sound.
Generally speaking, the above are the types of connecting cables that we often use in the system. Maybe we did n’t pay much attention to the connection of signal cables and speaker cables. Take the signal cable as an example: in fact, it is as important as the blood vessels in the body! From the perspective of stability and long-term, we must use high-quality wire and high-quality plugs, and ensure that they are welded with high quality and trouble-free. Now no matter how busy or tired I am in engineering, I am used to soldering all the signal cables in the system myself. If I use a signal cable that has been welded by someone else to connect to the system,
Dongcheng Audio has always been committed to the high-end product quality route. In order to better serve customers, we will work harder with high-quality products, humanized sales models and intimate and convenient pre-sale, in-sale and after-sale services. You jointly shape a brand new professional audio field. Fuyang Dongcheng Audio Engineering Co., Ltd. warmly welcomes calls from all walks of life to discuss consultation and cooperation and sincerely serve you!
Between the stereo and the tripod, try to use three small pieces of foam double-sided tape, and stick it to the bottom of the stereo in a triangular position, and then put it on the tripod, so that the stereo has a certain adhesion between the tripod. Otherwise, the speaker may be accidentally brought to the speaker during use. The speaker can easily slip out of the tripod and fall to the ground. The sound of the sound outlet on the front baffle does not need to worry about the reflection hole, even if it is placed on a low cabinet. The sound is extremely susceptible to the acoustic characteristics and placement of the room where it is placed. When the sound is placed in different space environments, its sound effect will be different.
At present, the industry-accepted sound quality standards are divided into four levels, that is, digital laser turntable CDDA quality, whose signal bandwidth is 10Hz20kHz; FM broadcast FM quality, its signal bandwidth is 20Hz15kHz; AM broadcast quality, its signal bandwidth is 50Hz7kHz; telephone For voice quality, the signal bandwidth is 200Hz3400Hz. It can be seen that the sound quality of the digital laser turntable is higher, and the voice quality of the phone is lower. In addition to the frequency range, people often use other methods and indicators to further describe the sound quality standards for different purposes.
