Bosch LAS-BEAM-L

The LAS-BEAM-L, measures 911 mm (35.9”) tall and is equipped with eight 3.5” full range drivers each powered by a built-in, dedicated 100 W amplifier channel with enhanced processing by an on-board DSP module. This configuration produces 1 or 2 steerable audio beams with a typical throw of 25 metres.

To extend coverage from a single position, the LAS-BEAM-L can be stacked using the LAS-BEAM-E extender kit, enabling stacking of up to five LAS-BEAM-L columns.
This configuration increases sound pressure level (SPL) and beam shaping power, providing coverage of up to 70 metres and enabling the creation of up to four beams.

The beam can be digitally adjusted in real time using configuration software.

LAS-BEAM loudspeakers are engineered for acoustically complex spaces like airports, houses of worship, and commercial buildings, delivering crystal-clear sound, reliability, and flexibility for speech, music, and announcements.

The LAS-BEAM series integrates seamlessly with PA/VA systems like PRAESENSA and supports dual 100 V audio inputs and/or dual line-level input channels. Innovative monitoring options are available via the 100 V line. Various redundancy wiring configurations, including A+B wiring and Class A loop wiring, can be implemented. In the event of an error, an alarm can be triggered in the PA/VA system through the 100 V line, with full support for PRAESENSA End of Line technology.

With a frequency range of 70 Hz to 18 kHz, the LAS BEAM-L delivers superior audio performance that exceeds life safety requirements, making it suitable for commercial applications such as spherical messaging and background music.
