A. The auto calculation routine will tend to aim the top cabinet slightly beyond
the coverage stop distance to give maximum vector summation at the furthest
listening position. This is physics at work and is not a shortcoming of the W8 Series
line arrays.
One benefit of this overshoot is that it can act as a hedge against coverage shortfalls
caused by temperature and wind gradients bending the projected sound downwards.
See W8L Series Applications Guide for further information about temperature and
wind gradients.
Reducing reflections and overspill
ViewPoint
tm
's auto calculation routine is based on a combination of theoretical
modeling* and practical experience and aims to give the most consistent frequency
response over the audience surfaces as well as an even SPL distribution. We strongly
recommend using ViewPoint
tm
's recommendations before attempting radically
different schemes.
If there are highly reflective surfaces (or level sensitive neighbours) immediately
beyond the
Coverage stop point you may wish to reduce the level and overshoot at
that point. This may be done by reducing the coverage stop distance until the top
cabinet ray coincides with the highest/furthest audience area.
