DSPPA MAG6000 IP PA System

Solution Overview

As a large-scale transportation base, the airport is composed of four major building structures: the main building, connecting building, corridor and elevated corridor, with total area of 300,000 square meters. It is an important transportation hub, connected to many domestic and international air routes. In response to the needs of our customers, it can broadcast the flight dynamics, business information, special announcements and emergencies of the airport in the public areas and office areas of the airport terminal.

Project Design Requirements

DSPPA MAG6000 network PA system integrates background music, public address, information release broadcasting, and emergency broadcasting to meet the needs of the airport for public address system. In addition, the system can automatically adjust the sound pressure level of broadcast sound reinforcement according to the changes in the environment noise of the sound reinforcement site. It is a highly integrated and intelligent public address system based on computer network technology and distributed construction, which makes it the first choice for airport public broadcasting.

Combined with the physical location area of the airport and the functional area, it is divided into several zones: outside the terminal building, the waiting hall, check-in area, ticket area, and office area. Configure network decoding terminal, power amplifier, main and standby power amplifier switcher, environmental noise self-sensing probe, network speaker line detector, and loudspeaker in each functional zone.

System Features:

1. Host dual-backup design: The system adds a standby host to ensure the normal operation of the system as the standby host can automatically go online when the host fails in an emergency.

2. Background music playback and zone management: In order to create a relaxing and comfortable flight and working environment, the public areas of the airport should play appropriate music to match the environment and increase comfort and intimacy. It can broadcast flight information and time as well as airport precautions to all zones or a specific zone.
3. Timing and paging broadcast function: The airport can broadcast the project promotions, release information about inbound and outbound flights, preset a schedule for one day and one week, and broadcast voice information and advertisements regularly. You can also use smart paging station for broadcast paging to different zones, such as paging to find people, paging friendly reminders and warm greetings to some specific zones.
4. Automatic switching function of system main and standby amplifier: Considering the importance of airport voice broadcasting, it is not allowed to have information release stagnation in the broadcasting system, and each broadcasting zone is equipped with a main and standby power amplifier switcher. When the main power amplifier fails, the main and standby power amplifier switcher will automatically detect and automatically switch to the standby power amplifier to ensure the normal operation of the airport network broadcasting system.
5. System speaker line automatic detection function: Each zone is equipped with a network speaker line detector MAG6424, which can detect the working status of each speaker line in real time on the host. Because most airports use buried wiring when installing equipment and wiring, once there is a problem with the speaker line, it is extremely difficult to troubleshoot the fault due to large amount of work, but the line detector can be used to detect each speaker line in real time. Once a fault occurs, it will appear the error prompt sound, which is more intelligent, convenient and fast.
6. Automatic adjustment of the broadcast sound pressure level when the environment noise changes on the sound reinforcement site: In order to make the voice broadcast information can be heard by each passenger and staff, the environmental noise self-sensing probe POE1028 is configured in the waiting hall, ticket hall, and check-in gate, for broadcast tracing, flight information broadcast, product promotion, safety tips, etc. As there are a lot of people in the airport and the airport space is large, there will be high environmental noise, and the broadcast information will be unclear due to the interference of environmental noise if the sound pressure level is too low. Therefore, the automatic sound pressure level adjustment function is indispensable for business broadcasting in public places while protecting the acoustic environment, which effectively guarantees and improves the efficiency of information dissemination.
7. Fire linkage and emergency broadcasting: The system can be linked with the fire center through the fire linkage terminal. When encountering a special accident or fire, the terminal will feed back to the host after receiving the alarm signal from the fire center to force the system to cut off the background music and business broadcast and enter the alarm working status to broadcast emergency information through the emergency broadcast microphone or fire pre-recorded evacuation voice broadcast, so as to guide passengers and all persons to leave the scene safely, prevent chaos on the scene, and reduce losses to a minimum.
