La-1 UW24?x is an affordable, all-purpose, 24-w voice string for indoor applications that require direction, such as religious venues, venues, meeting rooms and dining halls. It is standard with a rotating wall mount. Offers black and white styles of sound pillars. The MDF (medium density fiberboard) body, which is strong and durable in basic functions, is covered with durable and easy-to-clean vinyl film, providing both white and black styles. The front panel is made of ABS material and is covered with fine color matching speakers. These powerful sound pillars are equipped with four dual tone basins and high sensitivity speaker drive units. All Bosch speakers are certified to meet IEC 268-5 power handling capacity (PHC) standards and can operate continuously for 100 hours at rated power. Bosch has also conducted simulated acoustic feedback exposure tests to ensure they can withstand twice the rated power in a short period of time. This ensures high reliability in extreme conditions, improves customer satisfaction, extends service life, and significantly reduces the chance of failure or performance degradation. It is safe to install/configure the sound column in accordance with EN 60065 standard. The back panel is equipped with convenient and easy to use four-way pole push - in connector box, suitable for field wiring. The junction box provides a power tap connection for the 100 V matched transformer in the sound column. This allows the user to select the rated full power, half power rate, or quarter power radiation (increase by 3 dB)
