Certifications and Approvals All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 268-5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that they can withstand two times their rated power for short durations. This ensures extra reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and much less chance of failure or performance deterioration. Safety

Installation/Configuration Notes
Features ▶ Good speech intelligibility and background music reproduction
The column loudspeakers can be wall mounted using the supplied swivel bracket, allowing accurate positioning. A convenient, easy-to-use, four-pole push-in terminal block is present on the rear panel for on-site wiring. This terminal block has provision for power tapping on the 100 V, matching transformer in the cabinet. It allows selection of nominal full-power, half-power or quarterpower radiation (in 3 dB steps).
▶ For applications where directivity is important ▶ High sensitivity ▶ Swivel wall-mounting bracket supplied as standard ▶ Available in black or white ▶ MDF construction ▶ Complies with international installation and safety regulations
The LA1-UW24-x is a 24 W, general-purpose, cost-effective column loudspeaker for indoor use where beaming is desirable, such as places of worship, conference venues, meeting rooms, and canteens. A swivel wall-mounting bracket is supplied as standard. The column loudspeaker is available in black and white.

LA1‑UMx0E‑1 Metal Column Loudspeakers
Protection Both loudspeaker columns have built‑in protection to ensure that in the event of a fire damage does not cause failure of the connected circuit. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation. Connections and safety The loudspeaker columns have a ceramic terminal block, thermal fuse, and heat-resistant, high-temperature wiring. The column has a provision for internally mounting the optional line/loudspeaker supervision board.
4
Loudspeaker output power setting Four primary taps are provided on the built‑in matching transformer. Loudspeaker output power setting is done on the build-in transformer and connected to a rotary vary‑tap switch located in the back of the enclosure to allow simple output power setting. An 8 ohms setting is also provided on the rotary vary‑tap switch.
Certifications and Approvals Features ▶ Good speech intelligibility and background music reproduction ▶ For applications where directivity is important ▶ Slim-line weatherproof design ▶ Swivel wall mounting bracket supplied as standard ▶ Robust aluminum construction ▶ Switchable between 70/100 V line and 8 Ohms ▶ Provision for inside mounting of the optional line/ loudspeaker supervision board
