Description
Overview
The Macsys PAS-NBS20 is a cutting-edge communication device designed to deliver superior audio performance and flexibility. It employs a high-speed, industrial-grade dual-core chip combining ARM and DSP technologies, ensuring robust processing power for optimal performance. The device supports versatile voice encoding options, including both narrowband (G.711a/u) and broadband (G.722), providing crystal-clear voice paging for various applications.
The PAS-NBS20 is engineered to handle paging from SIP phones through 10 dedicated multicast addresses, enhancing its efficiency and scalability. Its multicast scalable function optimizes SIP account resources, making it a practical choice for expansive systems. Fully compatible with standard SIP protocols, the PAS-NBS20 integrates seamlessly with SIP PBX systems.
Additionally, the device supports multiple functionalities, including background music, emergency paging, and alarm signals, all managed through the Macsys management system. It features dynamic volume control that adjusts automatically based on ambient noise levels to ensure consistent audio quality. The PAS-NBS20 offers flexible deployment options with DC 24V, PoE and PoE+ interface support, making installation straightforward and adaptable. Furthermore, its Management is streamlined through web configuration, remote administration, and online firmware upgrades, while scheduling supports server-pushed tasks and HTTP push/SDK for serverless triggers. Integration extends to ONVIF pull with credentials, configurable RTSP, alarm I/O with action mapping, and acoustic loop self-check with server-side status display
