Bosch Vari-directional ArrayBosch’s new Vari-directional Array active line array claims to ‘set new standards for speech intelligibility and overall audio quality in commercial audio’, using digitally-controlled directivity to provide pattern control and distribution for ranges of up to 50m.

The array’s configuration software uses a database of pre-programmed room settings to fit different acoustical environments – an installer enters the room dimensions and requirements and the software makes the necessary calculations for set-up. It is also possible to customise audio processing and set supervision parameters. All amplifier and loudspeaker components (including drivers) are fully supervised, faults logged, and a 24V DC backup power supply can be connected. The system is also fully EVAC compliant for use in voice-alarm applications.

The modular-design of the range consists of a base and extension units that are connected together. The configuration software can automatically detect a connected extension unit, reducing configuration time. The base unit alone can cover up to 15m and the addition of an extension increases range up to 30m. Adding two extensions provides coverage up to 50m.

The array can be wall-mounted using mounting bracket supports that can be turned up to 80°, and have front amplifier cooling so flush-mounting in walls is also possible. The system is effective in counteracting the reverberant effect of hard construction materials in spaces such as airports of houses of worship.
