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 chal-
lenges. 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 microphone 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 IC8-R-II you can select up to a maximum of 4 beams. It’s up to
eight on an IC16-R-II, 12 on an IC24-R-II and 16 on an IC32-R-II.
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 identified with a dark blue aiming point.
The Center field and the drop down arrow and slider associated with it allow you to
move each beam’s acoustic center up and down the length of the array.
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 maintain consis-
tent high to low/mid frequency balance throughout the room.
Take a few minutes now to become
acquainted with the many design possibili-
ties 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 number of beams increases, the
output level of the individual beams
decreases.
