American Samoa International Airport by CMX DI-9700 IP system

As American Samoa's core aviation hub, Pago Pago International Airport requires high-standard PA system professionalism, stability and emergency response. CMX leverages its IP audio, EVAC and 5G conference expertise to customize the DI-9700 IPPA solution, fully meeting the airport’s terminal and peripheral broadcasting & scheduling needs.

The CMX DI-9700 IP PA system is based on IP network transmission, integrating audio encoding, intelligent broadcast control, real-time equipment monitoring and emergency linkage. The solution for the PPG airport follows the logic of Core Control - Signal Encoding - Voice Scheduling - Terminal Audio Output - Network Support, with all devices collaborating to build a highly adaptive IP PA system for airport scenarios:

• Core Control Layer: DI-9700SF software as the core, integrated with server, encoder, timer and monitoring functions; matched with DMT200 player and PA-100PR preamplifier to enrich audio input, optimize signal processing and support daily broadcasting and equipment monitoring.
  
• Signal Encoding Layer: DI-9710 encoder realizes analog-to-digital audio conversion for stable IP transmission, and connects with fire protection and other third-party systems to achieve emergency signal linkage.
  
• Voice Scheduling Layer: 5 sets of DI-9700TM remote microphones with 7-inch touch screens support multi-zone control, single/multi-zone broadcasting and two-way intercom, meeting the needs of cross-regional real-time scheduling and voice announcement.
  
• Terminal Audio Output Layer: Scenario-based deployment of terminal devices — 3 DI-97603 POE horn speakers for outdoor areas, 1 DI-97601 POE wall mount speaker and 3 DI-97501 POE ceiling speakers for indoor terminal areas. All POE speakers realize integrated data, control and power supply via a single CAT5/6 cable, with DI-9760 60W IP amplifier to enhance audio coverage.
  
• Network Support Layer: 16-port POE switch provides stable network and power supply for all terminals, built on the airport’s existing LAN/WAN network without separate dedicated wiring.
  

This solution fully fits the airport’s actual operational needs and provides three core supports:

1)Streamline Daily Operations & Improve Broadcast Efficiency

Intelligent timed broadcast and independent multi-zone management automatically complete flight announcements, background music and other daily tasks, reducing manual operations. Remote microphones enable real-time cross-regional voice scheduling, efficiently meeting daily communication and notification needs.

2)Strengthen Emergency Response & Ensure Operational Safety

Seamless connection with fire protection and emergency systems enables zoned/overall emergency announcement in critical situations for fast transmission of emergency information. All POE terminals are equipped with DC12V backup power, ensuring uninterrupted emergency broadcasting even during power outages.

3)Adapt to On-site Infrastructure & Reduce O&M Costs

POE power supply based on the existing IP network greatly cuts wiring and construction costs. Real-time equipment monitoring facilitates quick fault troubleshooting and lowers maintenance difficulty. The system supports flexible expansion of devices and zones, and can be upgraded agilely to match the airport’s evolving operational needs.

The implementation of the CMX DI-9700 IPPA system at PPG International Airport is a successful application of IP network public address systems in aviation hub scenarios. CMX will continue to develop scenario-oriented audio and video solutions, providing practical and reliable technical and product support for global transportation hubs and public venues.
