LA1 UW36?x is an affordable, universal 36w voice string for indoor applications that require direction, such as religious venues, venues, meeting rooms and dining halls. It is equipped with a standard rotating wall bracket, providing 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 rear panel is equipped with convenient and easy to use four-pole push - in junction box, suitable for field connection. The junction box is connected by a 100v transformer pick-up power tap in the sound column. The user can choose the rated full power, half power, or quarter power (increase by 3 dB).
