5. DSP PRESET PARAMETERS

The use of a line array has a number of advantages in different contexts, in particular:
• Homogeneous SPL along the front line of the speakers, an effect that is particularly noticeable over
medium to long distances
• directional acoustic behaviour, which allows the sound to be accurately focused on the audience,
avoiding unnecessary dispersion in areas where sound coverage is not required.
The achievable optimization of the line array takes into account the behaviour of the system with respect
to frequency:
• increasing the distance to the line array increases air attenuation. This has an effect especially on the
high frequencies.
• as the angle between the line array elements increases, the mid-frequency phase coupling decreases.
• As the number of line array modules increases, the low frequencies will add up in an acoustically
consistent manner.
The line array acoustic configuration of the VIO L212 modules can be optimized, thanks to the control
functions managed by the DSP. The local user interface is simple and immediate: it uses two rotary of the
"DSP Preset" section:
• Parameter calculation is carried out with dBTechnologies Composer. It is possible to select locally said
parameters on the VIO-L212 panel and use the remote control through AURORA NET.
• Position the rotary "SPEAKER COUPLING" according to the number of modules used in the line array.
This rotary acts on the low frequencies and must be set in the position:
• All these parameters can be adjusted with the remote control, once the RDNet connections have
been properly made, using the free AURORA NET software. When using the remote control, the local
controls on the panels of the VIO-L212 modules are by-passed.
