System is applied to a school, the functions can be realized are as follows:

School background music broadcast
Timing of realization of different partitions programmed to play different music in the school’s
classroom, restaurant, dormitory and public areas Area, making students feel at home.

School fire linkage function
Integrate with school fire protection system, according to pre-set fire alarm mode, the teachers
and students can evacuate accurately, to avoid maximum casualties and property losses.

Remote paging
At the school reception, staff can broadcast to specific zones or all zones.

Multi-source selection function
In the school’s restaurant, dormitory, classrooms and other areas, set up a local source,
can switch to the network and select background music.

Sub-control Function

IP Audio System is based on TCP/IP protocol. It transfers audio signal and control signal via network cable. As it can use the existing network system of the building, it can save cable laying and it is more convenient to arrange zones.
DSPPA has 2 IP PA Systems, one is MAG6182 IP Network PA System, which can link up to 250 zones or even more; the other is DSP9100 IP Network Audio System, which can link up to 200 zones. They are optical PA solutions for medium and large PA projects like airports, railway stations, shopping malls, supermarkets, parks, schools, hospitals, churches, mosques, etc.
MAG6182 IP Network PA System is specially designed for large Public Address System and General Alarm System (PAGA System). It can work within LAN network and can work across different networks. The default zone control of this system is 250, and it can be extended to unlimited zones via VPN network. The console of this system is MAG6182, and end user can set up the whole network system using the main software MAG6180, without the console MAG6182. It supports computer remote control via software MAG6100.
MAG6182 adapts modularized technology, while all kinds of functions can be extended via different modules, like Audio Inputs, Monitor, Fire Alarm, TEL Input, etc.
DSP9100 IP Network Audio System is specially designed for medium PA System. It supports console off-line operation and auto running after the system is set up. The remote control and paging station DSP9101 can even control each terminal and make remote paging after the console is off-line. The console of this system is DSP9000, and end user can set up the whole network system using the main software DSP9000, without the console DSP9100.
Both MAG6182 IP Network PA System and DSP9100 IP Network Audio System have a whole set of terminals, like IP Amplifier, IP Speaker, IP Remote Paging Station, POE Speaker, etc.

Digital wireless microphone system provides high quality transparent audio. This is largely due to the absence of a “compression expander” for digital wireless microphone system, which is a circuit for all analog wireless microphone systems to reduce noise and maximize dynamic range. Audio signals are compressed through transmitters to accommodate the limited dynamic range during FM transmission, and then expand in receivers.

Although the compression and expansion process is relatively small in most excellent analog systems, there will still be some artificially audible sounds (such as the wheezing effect) that will make the sound of wireless microphones slightly different from that of wired microphones. Since the use of digital wireless microphones, the transmission of audio signals no longer requires compression and expansion, and the received signals restore the precise characteristics of the original audio.

Compression expander (variable)

A digital wireless microphone system can reach the whole audible audio range with a flat frequency response curve.

Digital wireless system converts analog audio into digital signal by modulating radio carrier in several steps. The digital audio signal reach the receiver without the influence of electromagnetic noise. Any RF noise below the threshold does not affect audio quality. The receiver simply ignores anything that is not 1 or 0. Everything else is discarded. Only digital signals can be identified.

Longer battery life

Usually, the electronic wireless microphone system has a 30% to 40% longer battery life than the same analog system. The digital signal transmitter can run for 11 hours with two AA alkaline batteries.

Better spectral efficiency

By allowing tighter channel spacing, digital wireless systems can simultaneously use more effective compatible frequencies within a certain frequency band. This feature is particularly important in the increasingly crowded UHF TV bands operated by many wireless microphones. With the help of manufacturers and models, digital wireless systems can usually deliver twice as many frequencies as analog wireless systems can use.
