Point Source Array Modules
Most vertical line arrays are not assembled in a
straight line as their name implies. Instead they
are constructed in either a curved or a J shape
or a combination of both shapes to obtain the
proper sound coverage.
The shape of the array is typically determined
by the flying hardware and the splay between
the cabinets can easily be different than what is
optimum from an acoustical standpoint.
The VARIA approach is based on the use of 3
different shape cabinets each having a vertical
coverage pattern that is complementary to the
cabinet shape. Thus, the VA/VAX101-7 has 7.5º
sides and 7.5º vertical coverage. As a long throw
cabinet, its normal position is at the top of multi-
cabinet arrays.
The subwoofers can also be used as a platform
for flying the full range modules beneath them.
Up to 6 full range modules and two subwoofers
can easily and safely be flown in this fashion.
Please refer to page 3 for a list of connecting
bars.
VARIA also offers a choice of horizontal cover-
age patterns; 90º is standard, but 60º is offered
for when the audience are is long and narrow
and 120º for when a broader pattern is needed.
Please refer to pages 17, 19 and 21 for listings
of available coverage patterns.
VARIA also recognizes that in many cases a
trapezoidal pattern is needed; one wider in the
front of the room and narrower in the rear and
offers waveguides that transition smoothly from
60º to 90º and from 90º to 120º.
Subwoofers aren’t ignored either and the VA/
VAX15S subwoofer that served as a base for
ground stacked arrays can also be used as a
suspension platform for flown arrays
