The LA1-UM40E-1 is a professional metal column loudspeaker designed to deliver excellent speech intelligibility and high-quality background music reproduction in environments where controlled sound direction (beaming) is essential. Housed in a robust yet elegantly designed white aluminum enclosure, this slim-line speaker is suitable for both indoor and outdoor applications, including passenger terminals, places of worship, conference venues, theme parks, swimming pools, factories, and exhibition areas. A swivel wall mounting bracket is supplied as standard, allowing precise positioning for optimal sound coverage.

Engineered for voice alarm applications, the LA1-UM40E-1 is designed to meet regulatory requirements for public address and emergency systems. It features built-in protection to ensure that, in the event of a fire, damage to the loudspeaker does not cause failure of the connected circuit, thereby maintaining overall system integrity. The unit is equipped with a ceramic terminal block, thermal fuse, and heat-resistant high-temperature wiring for enhanced safety and reliability. It also provides the option for internal mounting of a line/loudspeaker supervision board.

The built-in matching transformer offers four primary power taps, with output power easily adjustable via a rotary vary-tap switch located at the rear of the enclosure. An additional 8-ohm setting is included for flexible system integration. Combining durability, safety compliance, and focused sound performance, the LA1-UM40E-1 is an ideal solution for professional installations where clarity, reliability, and directional audio control are required.
