DVA Composer is an easy-to-use software program for configuring and aiming dB Technologies DVA Series of active line array and subwoofer modules. A useful tool to aid audio engineers plan and deploy the dB Technologies system, the software is designed for intuitive handling, determining the optimum angles and system presets based on the array height, desired range and number of DVA components entered by the user; provides all the mechanical data, frame angle positions and flybar settings; and determines the proper DSP EQ presets.
In the initial Composer section, the user is able to insert facility measurements to effectively determine coverage. Settings include flybar position and height of system, stage dimensions, trussing framework, gap width of L-R arrays, as well as coverage start and end positions, and whether audience is standing or seated. It also allows the user to modify the angle of the ground, and add up to three balconies. From that data input, the user can then view a graph and see the actual prediction of the system including coverage with SPL readings in both graph and prediction views, with the ability to review SPL measurements at different frequencies and distances.
The user is also provided the ability to choose among three different shape modes – J shape, curved array, and hybrid – may be selected to further adapt the system to suit the given venue.
DVA Composer also computes subwoofer configurations and determines the directivity of low frequencies based on the type of setup and number of units. The subwoofer simulation provides the user to choose between six available ground stacked configurations – left-right, center, left-center-right, line, cardioid and endfire. Each configuration also allows the choice of subwoofer dispositions (i.e. vertical or horizontal) and provides the ability to arrange the subs differently for left/right channel and center channel. The subwoofer data determines crossover frequency, delay, phase, position of the subs frontline and the gap between subs as necessary.
DVA Composer 4.0 “is far superior to the original DVA Shape Designer,” says RCF USA technical engineer Tarik Solangi.
