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.

Functions
The robust, solid MDF (Medium Density Fiber board) enclosures are covered with a durable, easy-to-clean vinyl in a choice of black or white. The ABS fronts are covered with fine woven cloth in matching color. These powerful column loudspeakers are fitted with four dual-cone, high-sensitivity, loudspeaker drivers.

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.

Installation/configuration notes
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 quarter-power radiation (in 3 dB steps).
