Loudspeaker Fanvil FH-S01 20 W

FH-S01 is a SIP ceiling loudspeaker designed for paging, multicasting, broadcasting and two-way talkback in conferencing and public address environments. The Fanvil FH-S01 20 W delivers clear voice intelligibility using G.722 and Opus codecs, supports standard SIP 2.0 (RFC3261) and related RFCs for wide compatibility, and can be configured for up to 10 multicast zones with priority control. The unit features a wired connection, 20 W RMS power, 8 Ω impedance, 100–20000 Hz frequency response and a white finish suitable for ceiling installations.

Advantages

The FH-S01 provides high speech clarity through support for G.722 and Opus codecs and offers multicast paging across up to 10 zones with prioritization. Compliance with SIP 2.0 (RFC3261) and related protocols ensures interoperability with standard VoIP and conferencing systems. Its 20 W RMS power and 89 dB sensitivity deliver reliable acoustic output for meeting rooms and public address applications, while the wired connectivity and 8 Ω impedance simplify integration into existing audio systems.

Suitable for

• Conference rooms and meeting spaces
• Office paging and announcements
• Public address in schools, hospitals or retail
• Multizone broadcasting and emergency paging

How to use

Mount the FH-S01 in the ceiling according to local building and safety regulations and connect it to your SIP-enabled network using the wired interface. Configure SIP account and network settings via your SIP server or management interface, assign multicast zones and set zone priorities as required. Adjust system-level gain and equalization from the conferencing or PA controller to achieve desired speech clarity and coverage. Test paging, broadcasting and talkback functions after configuration.

Recommendations

For optimal intelligibility, place the speaker centrally in the coverage area, set audio levels conservatively to avoid distortion at 20 W RMS, and use G.722 or Opus codecs when low-latency, high-quality voice is required. Verify multicast and priority settings during commissioning to ensure correct behavior in multizone installations.
