12" DSP Steerable Line Array
Series: Messenger
Model: Messenger M
- Fully digital sidelobe-free speaker array
- Triple-lobe feature for the ultimate accuracy in lobe design
- Tightly controlled beam, up to 5 degrees, which can be shaped in nine steps to meet each specific application/environment
- A-symmetrical and symmetrical arrangement by means of software control
- Integrated DSP control with 7 band parametric EQ, noise gate, delay rooms, peak limiter, VOX-control on priority input and level raising microphone for ambient noise sensing
Each Messenger array has a very tightly controlled beam, which can be shaped as required for specific applications or environments requiring symmetrical or asymmetrical, single, dual or triple lobe design. The availability of high powered DSP's such as the Texas Instruments™ which provides 24 channels of precise control by means of additional process channels, results in a very powerful array, where the SPL stays within +/- 3dB over a distance of 100m.
Messenger range is completely software controlled, this lobe control/variable acoustical centre can compensate for architectural requirements and can be easily adapted for specific types of application. Its flexible mounting height of between 1.2 and 4m above ground level ensures the array can be securely positioned out of reach. Messenger available in 5 different sizes Messenger M, Messenger L, Messenger XL, Messenger 2L and Messenger 2 XL.
