• A - 1 to 2 speakers
• B - 2 to 4 speakers
• C - 5 to 6 speakers
• D - 7 to 8 speakers
• E - 9 to 10 speakers
• F - 11 to 12 speakers
• G - 13 speakers and beyond
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 areas where acoustic coverage is not required
• 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 decreases mid-frequency phase coupling
• as the number of line-array modules low frequencies add together in an acoustically coherent fashion
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” (4) 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:
