Vari Base Unit Bosch LA3-VARI-BL

Bosch LA3-VARI-BL is a white active vari-directional array speaker. It utilises integrated digital signal processing and high efficiency class-D amplifiers. Using a PC configuration program the array can be adapted to the venue where it is used and its sound output optimally aimed at the audience, creating a maximum direct to ambient sound ratio, for best intelligibility given the circumstances.

The modular concept allows you to choose three different array lengths for different sizes of premises. Using separate array elements to simplify transportation; it is also possible extension of the array.

Optional CobraNet module allows you to combine an array of the network receive digital audio via CobraNet and control the operating status of the speaker. The array is suitable for providing background music or speech for transmission.
