Superior technology for superb acoustics Hard construction materials, applied in buildings such as railway stations, airports, places of worship and conference centers, lead to disturbing reverberation. Vari-directional Arrays from Bosch overcome this challenge to deliver unmatched acoustical performance in difficult environments. Thanks to digitally controlled directivity, sound is only sent where it is needed, producing an optimal sound field with perfect speech intelligibility. The sleek, unobtrusive design looks great in any environment, and the modular units can be mounted flat against the wall or even flush-mounted. Supervision, backup power, and optional support for CobraNet™ extend the options even further.
