The principle behind the operation of MLA is based on the combined mechanical/digital control of directivity. Digital allows for the control of directivity up to around 4KHz; mechanical, assisted by digital, from 4KHz to over 15KHz. This enables the system to reach the following targets:

• An aesthetically non-intrusive vertical column that is readily adaptable to any environment
• Control of full-range directivity from the lower frequencies (depending upon the length of the column) up to and over 15KHz
• Elevated SPL, thanks to the usage of a compression drivers e wave guide at high frequencies
• LImited number of transducers and therefore DSP channels and amplifiers associated with “no compromise” systems of exclusively digital steering with drastic reduction of cost.

The modularity of the system allows for the construction of a column composed of a  maximum of two MLA801a modules and 3 ML608A modules for a total of 4000W and a minimum frequency control of 100hz!

For usage in fixed installations, bars are provided for the close-fitting installation adjacent to walls. For live usage, an accessory is available for positioning on the 118Sa and 121Sa subwoofers of the FBT MITUS series.

VERTUS MLA is a column speaker system with vertical directional characteristics  fully controllable by the user both for the steering of the radiation lobe and for the width and form of the lobe itself.

The characteristics of the lobe radiation directional controls, the high SPL, the Hi-Fi frequency range, the elegance and overall dimensions, make the MLA system particularly suitable for high quality sound even in acoustically difficult environments, reverberating and very large, given the capacity of the wavefront to soften of about 3 dB upon doubling the distance from the source. Thus, it is ideal in large churches, theatres, auditoriums, large convention and multimedia halls, as well as in public places such as airports, railroad stations, etc...
