3. DSP PRESET PARAMETERS AND REMOTE CONTROL

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 behavior, 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 behavior 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 L208 modules can be optimized, thanks to the control
functions managed by the DSP. The interface for use is simple and user-friendly: it uses two rotary controls
of the "DSP Preset" section (4) and refers to the explanatory label on the side of the amplifier:
• 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:
• A - 2 to 6 speakers
• B - 7 to 8 speakers
• C - 9 to 10 speakers
• D - 11 to 12 speakers
• E - 13 to 14 speakers
• F - 15 speakers or more
• G - to enhance the low frequencies (front fill
or stand-alone use)
• Position the rotary "HIGH FREQUENCY COMPENSATION"
according to the installation type and angle set in the line array.
This rotary acts on the mid-high frequency range and must be
set in the position:
