Available on back-order

The Grandstream GSC3506 V2 SIP Intercom Speaker is a high-power SIP/Multicast public address speaker designed for large-scale paging, announcements, and emergency broadcast systems in commercial, industrial, and institutional environments. It delivers crystal-clear HD audio through a 30W high-fidelity acoustic chamber, making it suitable for loud, wide-area sound distribution.

It supports integration with SIP systems, IP PBXs, and multicast paging networks, allowing organisations to deploy scalable voice announcement and security alert systems across multiple zones or buildings.

Ideal For

  • Office and enterprise paging systems
  • Schools and universities
  • Hospitals and healthcare facilities
  • Warehouses and factories
  • Retail and hospitality environments
  • Public safety and emergency alert systems

Benefits

The GSC3506 V2 is built for high-volume, high-clarity audio broadcasting, making it ideal for environments where messages must be heard clearly over background noise.

Its SIP and multicast paging capabilities allow flexible deployment across large networks without complex analog PA infrastructure. Priority override ensures urgent alerts can interrupt ongoing broadcasts when needed.

Because it integrates into SIP ecosystems, it can be centrally managed alongside other Grandstream devices such as IP phones, intercoms, and access control systems.
