Grandstream GSC3506-V2 SIP/Multicast paging Speaker
Clear, powerful paging meets flexible SIP communication in the Grandstream GSC3506 V2, a 30W SIP paging speaker built with an HD acoustic chamber for high-fidelity voice broadcasting. Supporting multicast and group paging, push-to-talk (PTT), and PoE/PoE+/PoE++ networking, it fits public address and security communication setups that require clear audio and flexible deployment.
The Grandstream GSC3506 V2 provides high-fidelity SIP paging for offices, schools, hospitals, apartment complexes, and other facilities that require clear voice announcements. Its 30W coaxial speaker and integrated HD acoustic chamber are supported by full-band and wideband audio codecs, including Opus and G.722, for detailed speech reproduction. The speaker supports SIP paging, multicast paging, group paging, and push-to-talk (PTT), while call-waiting with priority override helps manage announcements alongside active communication.
Connectivity and peripheral integration are handled through a 10/100 Mbps network port with PoE, PoE+, and PoE++ support, along with an auxiliary 24V DC power input. The GSC3506 V2 also provides a USB 2.0 port for external storage, a 2-pin switch-in interface, a 2-pin alarm-in input, and a differential line-out connection for flexible installation requirements.
