Now, let’s investigate the multiple beam capabilities of Iconyx.
In many installations, a single beam is the ideal solution for the room’s
acoustical challenges. In some cases, however, multiple beams are needed to
provide the desired coverage. Rooms with a balcony are a good example; in
most cases a single beam can’t cover both the main floor and the balcony.
One solution is two line arrays, one for the floor and the other for the balcony,
but this is expensive. In other cases, architectural considerations or micro-
phone placement dictate that the column be mounted higher than is ideal and
it’s impossible to cover the audience area with a single beam.
Iconyx solves these problems by offering multiple beams, with each beam
having its own movable acoustic center. To explore this unique Iconyx
feature, click on the drop down arrow associated with the field showing the
number of Beams.
Notice that on the ICL-FR you can select up to a maximum of 4 beams. It’s
up to eight on a Dual ICL-FR. For now, select 2 to add a second beam to the
graphic.
At first glance it may appear that nothing happened since the program may
have placed the second beam on top of the first beam. One way to tell that a
second beam has been added is that the left side of the window now includes
a Beam Parameter Center 2 section. In the graph, the second beam is identi-
fied with a dark blue aiming point.
The Center field and the drop down arrow and slider associated with it are not
active in IC Live arrays as their acoustic center is fixed and cannot be moved.
Notice that the second beam also includes a Relative Level field. This allows
you to reduce the level of this beam relative to the first beam, a useful feature
when the second beam is covering the front of the audience area.
The High Pass at [Hz]
section lets you add high
frequency content to main-
tain consistent high to low/
mid frequency balance
throughout the room.
Take a few minutes now to
become acquainted with
the many design pos-
sibilities offered by Iconyx
steerable arrays by playing
around with the number
of beams, their opening
angles, their aiming and
their relative levels.
One of the things you will
notice is that as the num-
ber of beams increases,
the output level of the indi-
vidual beams decreases.
