Key benefits

  • Two-way SIP speaker with built-in MEMS microphones supports real-time talk-back in compact spaces.

  • In-ceiling installation offers a clean, unobtrusive appearance and easy integration into existing ceilings.
  • White finish blends with standard ceilings for a discreet look in offices, classrooms, and stores.
  • SIP and multicast talk-back enable scalable conversations and quick room-wide updates.

Notes on usage and installation: the in-ceiling form factor reduces cable clutter, while the MEMS microphones are designed for everyday voice capture. Performance will vary with room acoustics and speaker placement, so consider pairing with appropriate room design for best results. Designed for practical deployments, the GSC3516 is compatible with standard SIP networks and multicast groups, simplifying administration in mixed environments. The integrated design reduces the need for separate microphones and external amplifiers, while the white aesthetic supports a variety of interior styles.
