Background
After over twenty months of expansion and renovation, Mohe Gulian Airport, China’s northernmost airport, officially resumed operations, restoring the aerial route to the “Chinese Arctic.” As a 4C-level domestic tourist airport, it is the first airport built in a permafrost zone and the highest latitude airport in China.
Introduction
Operating in extreme cold requires equipment with high stability and reliability. To meet these needs, SPON Communications deployed its IP Matrix Public Address (PA) System at Mohe Gulian Airport. Known for resilience in low-temperature environments, the system ensures clear, reliable communication for both passengers and airport staff, maintaining operational efficiency under harsh conditions.
Design
The SPON IP Matrix PA System is designed for maximum reliability and safety. Its fault self-check and backup redundancy design detect anomalies such as under-voltage, power overload, amplifier malfunctions, or speaker line short circuits. When a fault occurs, the system immediately issues an alarm, displays the anomaly, and activates backup units automatically, reducing broadcast failure rates to near zero.
In addition, the system features automatic volume adjustment based on environmental noise, ensuring clear and pleasant announcements. Key hardware includes the XC-9508 IP Integrated Amplifier, which supports multiple audio inputs, individual volume control, offline broadcasts during network disruptions, and remote updates. The NAC-2305 30W 100V Wall-Mounted Speaker delivers waterproof, high-quality audio, with flexible installation options to provide optimal sound coverage for the airport’s public areas.
Why Choose SPON?
Transport hubs such as airports, subways, and railway stations require 24/7 broadcasting and command systems to manage massive passenger flows. SPON’s IP PA and intercom solutions support large-scale deployment with cross-regional management, offering low-latency, interference-resistant transmission. Even in noisy environments, messages remain clear and intelligible. Widely applied in passenger guidance, travel information, emergency evacuation, and control room operations, SPON ensures safe and efficient transport management.
