IC Live Users Manual, ICL-F & ICL-F-DUAL
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 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. To explore this unique Iconyx feature, click on the drop down arrow associated
with Beams. This will produce the following screen.
Notice that on the IC-16L you can select up to a maximum
of 8 lobes. It’s up to four on the IC-8L. For now, select 2 to
add a second beam to the graphic.
At first glance it may appear that nothing happened since
the program 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.
Notice that the second beam 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.
Take a few minutes now to become acquainted with the many design possibilities 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.
The graphic below was made using three beams in a room with a balcony.
