Aesthetically non-intrusive vertical column that is readily adaptable to any environment: Vertus MLA 608a for Mid/Low frequencies (60hz-2KHz) and Vertus MLA 801a for High frequencies (2KHz-20KHz).
This is a column system with a fully controllable vertical directional feature that can be adjusted by the user in terms of radiation lobe pointing, lobe shape and width. It is possible to emulate the directivity of a classic "J"-shaped line array, either curved or straight.
The operating principle of MLA is based on a combined Mechanical/Digital directivity control. The Vertus MLA system incorporates the advantages of both types of control, while at the same time overcoming their limitations. With digital control, it is possible to control the directivity up to 4kHz, associating different delays and filters with each transducer. Meanwhile, with mechanical pointing, it is possible to control directivity from 4 to 15 kHz, taking advantage of this method to create systems characterized by high SPL and precision. This allows for full-range directivity control.
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.
The MLA system features an RS-485 network connection for total control through PC. In mainly live situations, it is possible to manage steering, lobe width and equalization through three switch controls available on the back panel of the MLA column.
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 VERTUS MLA on the subwoofers. The extruded aluminum cabinet with powder coating ensures maximum strength and durability.
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.
