Is there a function to reduce Noise Elimination?
 The IP paging mic is built with the Noise reduction algorithm.
Can it work in cases where the server has network problems?
The IP paging mic supports offline calling without server software.
Support recording all incoming and outgoing call information. Including calls that have missed calls?
Yes, it supports
What should I do if other SPON® IP audio devices cannot be identified by the built-in web server of SPON® IP paging console?
  • Please check if the communication protocol of other SPON® IP audio devices has been set to NAS protocol, since the built-in web server can only identify other devices via NAS protocol.

Which Audio Formats are supported by SPON IP public address system? How much bandwidth is used?
  • The audio formats of IP Public Address are: MP2, MP3, AAC, etc. (MP2 and AAC are the standard designated audio formats of national DAB )

  • Compare of used Bandwidth: MP2: 256K-512K MP3: 64K-128K

Practical features of the IP PA system when applied to highways?
  • Background Music and Announcements: The system can play music, Emergency Broadcasting.

  • Situation Reports: It can announce daily activity schedules, provide key points about significant events, and give updates about essential convoys passing through.

  • Emergency Interjections: The system can be used to urgently intercept vehicles violating rules, grant access to special vehicles, and command on-site order during chaotic situations.

  • Emergency Paging: If a toll booth encounters an unexpected situation, operators can use a one-touch emergency call to the control center or neighboring toll stations for immediate assistance.

Where can digital IP public address systems be applied?
  • Schools, especially those equipped with campus networks.

  • Highway Toll Stations

  • Chain Supermarkets

  • Large Enterprise.

  • Office Buildings and Skyscrapers.

  • Rural Connectivity Projects.

  • Any location with network connectivity can benefit from the IP public address system.

How does SPON's IP public address system set itself apart from traditional PA systems?
  • High Audio Quality: The system offers pristine fidelity through its full digitalization, utilizing CD-like quality data file formats, which are perfectly consistent with computer output.

  • Personalization: Built on an Internet protocol, each audio endpoint can freely choose any channel for playback, with adjustable progress, allowing for point-to-point personalized programming.

  • Network Integration: From teachers' courseware production and arrangement to speeches and scheduled program broadcasts, everything can be operated remotely over the network.

  • Remote Functionality: The system supports remote broadcasting across different cities and even countries. As long as there's an internet connection, broadcasting can be initiated.
