Horn loudspeaker Bosch LHN-UC15W-SIP — 15W, wide angle, SIP network-compatible

Horn loudspeaker Bosch LHN-UC15W-SIP — 15W, wide angle, SIP network-compatible is a 15 W horn-type public address speaker designed to provide clear voice paging and background announcements in indoor and sheltered outdoor environments. The wide-angle acoustic design delivers focused coverage across a broad sector, helping to ensure intelligible speech in corridors, halls, warehouses and covered outdoor areas. SIP network compatibility allows the loudspeaker to connect to IP-based communication systems for centralized control and easy integration into existing SIP infrastructures.

Advantages

The Bosch LHN-UC15W-SIP combines a compact horn form factor with a 15 W output to balance reach and mounting flexibility. Its wide-angle dispersion improves speech intelligibility across a sector rather than a single point, reducing the number of devices required for coverage. SIP network compatibility simplifies installation and system integration, enabling remote audio distribution, control and monitoring via standard SIP endpoints. The construction is suitable for indoor and sheltered outdoor use, offering reliable operation for routine announcements, alerts and evacuation paging.

How to use

Mount the loudspeaker on a stable wall or ceiling surface within the area to be covered, orienting the horn to direct sound toward the intended listening zone. Connect the device to the building network and configure SIP settings according to the system administrator or SIP server instructions. Adjust audio levels from the SIP endpoint or central control system to achieve clear speech intelligibility without distortion. Follow local wiring and safety regulations during installation and ensure the device is protected from direct weather exposure if installed outdoors.

Usage recommendations

For optimal performance, position the speaker to avoid direct obstructions and mount at a height that supports even coverage. Use the SIP network features to centralize volume control and monitoring; perform periodic checks of audio clarity and network registration. For full area coverage, combine multiple units following a coverage plan rather than increasing single-unit output.
