DANTE AES67 Public Address Solutions

Because the sound energy of natural sound sources (such as voice speech, singing, musical instrument playing, sound reproduction, etc.) is very limited, the sound pressure level decreases with the increase of propagation distance, and the influence of environmental noise limits the propagation distance of sound sources. Therefore, in public places, it is necessary to use electronic technology-sound amplification system to amplify the sound source signal. Greater, improve the sound pressure level in the audience area to ensure that each audience can get the appropriate sound pressure level.

Public Address system is a systematic engineering, which requires close cooperation of many disciplines, such as electronic technology, electroacoustic technology, sound construction technology and acoustic art. The sound effect of public address system is not only related to the comprehensive performance of the electroacoustic system, but also closely related to the sound transmission environment, architectural acoustics and the use of on-site tuning. Therefore, the final effect of public broadcasting system needs to be correct and reasonable. The best combination of the design and debugging of electro-acoustic system, good sound transmission conditions and correct on-site tuning technology is indispensable to each other. In the system design, the above problems must be considered comprehensively. On the basis of choosing the electro-acoustic equipment with good performance, through careful system design, careful system debugging and good sound construction conditions, the electro-acoustic pleasant and natural sound effect can be achieved.

1. Traditional Public Address System Traditional public address mainly includes several functions, such as timing programming, zonal paging, telephone broadcasting access, and fire-fighting strong plug-in. Fire alarm access and business area broadcasting have been the focus, and no emergency, to achieve background music broadcasting, create a warm environment, foil an atmosphere.

2. Intelligent Matrix System Most intelligent public broadcasting systems are managed by a general PC (or an industrial control management host) and controlled by a general keyboard. The other links in the system are still routine, only computer interfaces are added. Others are more specialized series, which are operated directly on the host screen by a dedicated host (and, of course, a computer) that virtualizes all the links in the system except the power amplifier (including the sound source playback link). The main differences between the system and the conventional system are: small size, high integration, including the conventional series of zoning, timing, alarm, strong interpolation, paging, telephone, monitoring, voice file solidification, CD playback and other functions; the function is more flexible and perfect than the conventional system. If different programs need to be broadcast in different broadcast zones at the same time, most of them use the audio matrix system. Matrix systems can be allocated to different broadcast partitions through matrix partitioners. These programs can be broadcasted at the same time or at the same time. The programmable timer can run automatically according to the pre-programmed program, and can also intervene manually at any time. At present, there are many applications. Generally, the audio module is used to form a digital matrix, which can be divided into time zones, and multi-partition and multi-source input at the same time. Generally used in schools and hotels.

3. Digital Networking The interior of modern intelligent building requires the establishment of data network, video network and audio network. The network of public broadcasting transforms the traditional public broadcasting network into a data network, which connects the broadcasting terminal, VOD terminal, voice source acquisition/paging terminal, remote control terminal and other terminals, so that it is not only convenient to install and operate, but also can share resources in different places. MONISMS is also the industry's first high-tech enterprise to develop DANTE/AES67 audio protocol transmission, the earliest from teaching audition, teaching digital audio, to public broadcasting, digital conference, professional audio industry, have been in-depth application and promotion.
