The use of a line-array provides multiple benets in various contexts; in particular:
• Homogeneous SPL along the speaker front direction; the effect is particularly noticeable over medium
to long distances
• directive sound behaviour, allowing to accurately focus the sound on the audience, avoiding
unnecessary dispersions in large and reverberating environments
The line-array optimisation takes into account the system behaviour with respect to the frequency:
• as distance from the line-array increases, air attenuation increases as well. This particularly applies to
high frequencies.
• as the angle of the line-array components increases, the effects associated with soundwave
attenuation at medium frequencies increase as well.
• as the number of line-array modules increases the low frequency components becomes dominant
The DSP-managed control functions allow to optimise the line-array sound conguration of the DVA K5
modules. The user interface is simple and intuitive. It includes two rotary encoders installed in the “DSP
Preset” (7) section and the reference label shown below:
CONFIGURATION AND OPTIMISATION WITH DSP IN LINE-ARRAY
• Turn the “SPEAKER COUPLING” rotary encoder to set the number
of modules included in the line array. This rotary encoder
affects the low frequencies and must be turned to the following
position:
