DANTE Digital Network Public Address System
DANTE Digital Network Public Address System (PA system)
The digital network public address system uses DANTE technology to transmit audio signals in a standard IP packet over a local area network and a wide area network. It is a two-way audio sound system that transmits pure digital networks. It completely solves the problems of poor sound quality, complicated maintenance management and lack of interactivity in the traditional public address system. The system equipment is simple to use, easy to install and expand, and only needs to connect the digital audio terminal to the computer network to form a powerful digital public address system. Each access point does not need to be separately wired, and truly realizes computer network, digital video monitoring, public address (PA). Multi-network integration.
Multifaceted superiority editor
The IP network public address system (PA system) is a product completely different from the conventional public address system, the FM addressing broadcasting system, and the numerical control public address system. Because it is built on the common platform of IP network and incorporates multiple digital audio technologies, it has its inherent advantages in many aspects:
Each terminal can be independently controlled to play different content (for example, 200 terminals in the local area network simultaneously play 200 channels of programs). Not only can fully realize the functions of the traditional broadcasting system (such as: regular ringing, zone play, fire alarm, etc.), but also has functions such as free on-demand terminal and two-way intercom between terminals;
The audio transmission distance extends infinitely and can run on the LAN and Internet network across the gateway, supporting a wide range of important applications, from the main campus to the campus to centrally control the broadcast, from the company headquarters to the local branch of the simultaneous broadcast, to achieve fast Reliable communication of information.
The sound quality of the terminal output is close to the CD level (44.1K, 16bit), and the frequency response is 20-16khz, which meets the requirements for high sound quality, such as the entrance examination, the college entrance examination, the listening test of the college exams, and the daily foreign language listening training in the classroom. Each pronunciation can be clearly discerned and no longer plagued by ambiguous sounds.
The server (Windows operating system) and the main controller (embedded operating system) provide double insurance. If one party fails, the other party can take over all terminals to ensure the basic functions of the whole system are running normally; the main control unit and the terminal use industrial grade chips. Working 24 hours a day, and completely immune to viruses; the instability of traditional broadcasting depends on the quality of the transmission line, IP network public address with the help of mature Ethernet hardware, each terminal is equivalent to a simple PC connected to the network, no extra Maintenance.
