The campus IP network PA system is completely different from the traditional PA system, the FM addressing PA system and the numerical control PA system. Shenzhen OBTPA Technology Co., Ltd. campus IP network PA system is built on a common network platform and incorporates technologies such as digital audio. It has unique advantages in many aspects:
Functional aspects: Each terminal can be independently controlled to play different content. Not only can fully realize the functions of the traditional PA system (such as: regular ringing, zone play, fire alarm, etc.), but also has the functions of free on-demand terminal and two-way intercom between terminals, which can achieve good communication between teachers and leaders.
Sound quality: The output quality of the terminal is close to the CD level, which meets the requirements for high sound quality, such as the college entrance examination, the listening test of CET-4 / 6, and the daily foreign language listening training in the classroom. Each pronunciation can be clearly distinguished, no Troubled by the ambiguous sound;
Reliability: The network master of the server and campus IP network PA system provides double insurance. If one party fails, the other party can take over all terminals to ensure the basic functions of the system are running normally. Both the main control unit and the terminal use industrial-grade chips, which work 24 hours a day and are completely immune to viruses. With the help of mature Ethernet hardware, the entire system does not require additional line maintenance. After several years of experience and efforts, the OBTPA campus IP PA system has now reached a fairly stable state, and there is basically no sudden disconnection. .
Transmission: The audio transmission distance is infinitely extended. It can run on the LAN and Internet of the gateway across the gateway, supporting a wide range of important applications, from the main campus to the campus to centrally control the announcement, from the company headquarters to the regional announcement of the regional divisions, so as to achieve fast and reliable information communication.
The OBT campus IP network PA system can realize the purpose of announcing audio signals through the switch, and can realize two-way intercom, announcement, real-time collection, program timing announcement, leader online speech, online radio announcement, audio automatic trigger terminal equipment, fire alarm and many other features. The emergence of OBT campus IP network PA system once caused a sensation in the public address system field, setting off a wave of IP network PA system. Over the years, in line with the concept of “creating value for customers”, OBT campus IP network PA system is being favored by more and more schools!
