The digital control part is activated by discrete amplification channels (one for each  transducer) and DSP which operates in signal processing management sent to each speaker and driver.

 

The mechanical part is entrusted to 8 hybrid stepped motors, each of which is dedicated to

 

the rotation of wave guide by 0,01° steps on the horizontal axis. It is thus possible to activate any radiation pattern in the maximum rotation range of the wave guide which goes from +35 to -35 with respect to the horizontal axis.

 

The MLA system features a RS-485 network connection for total control through PC (with FBT USB-RS485 Converter) and dedicated software with which it is possible to simulate the environment to sound reinforce, select the appropriate dispersion pattern for the audience, transfer all the aiming parameters of the system through the network with a single button. Various types of autoplay routine enable a totally automatic configuration of the system, without precluding for the possibility of aiming ‘fine-tuning’ in manual mode.

 

In mainly Live situations, when time is limited and it isn’t possible to connect to a PC, it is  possible to manage steering, lobe width and equalization through 3 switch controls available on the back panel of the MLA column.

 

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...
