3. DSP PRESET PARAMETERS AND REMOTE CONTROL

Using a line array entails a series of advantages in various contexts, in particular:
• homogeneous SPL along the front vector of the speakers, an effect that is particularly appreciated
at medium to long distances
• directing acoustic behavior, which allows to precisely focus the sound on the audience, avoiding
unnecessary losses in areas where acoustic coverage is not required
Possible optimization of the line array takes into account the behavior of the system according to the
frequency:
• increasing the distance from the line array increases the air attenuation. This especially affects high
frequencies
• increasing the angulation between elements of the line array decreases mid-frequency phase coupling
• as the number of modules of the line array increases, low frequencies will add together in an
acoustically coherent fashion
The acoustic configuration in a line array of the VIO L210 modules can be optimized, thanks to the control
functions managed by DSP. The user interface is simple and straightforward: it employs two rotaries of the
"DSP Preset" (4) section and refers to the explanatory label placed on the side of the amplifier:
• Place the "SPEAKER COUPLING" rotary depending on the
number of modules used in the line array. This rotary acts
on the low frequencies and should be set to the position:
• A - from 2 to 6 speakers
• B - from 7 to 8 speakers
• C - from 9 to 10 speakers
• D - from 11 to 12 speakers
• E - from 13 to 14 speakers
• F - more than 15
• G - to enhance the low frequencies (front fill
or stand-alone use)
