IC Live Users Manual, ICL-F & ICL-F-DUAL
Now that we understand the basics of using BeamWare 2, it's
time to investigate one of the unique tools BeamWare 2
includes to even further speed the design process. It's called
Auto-Focus and it is available as a design aid whenever you
choose to use 2 or more beams. You'll find it in the IC
Configuration section next to Beams.
Clicking on Auto-Focus will open the setup window shown to
the right.
Since ICL-F arrays have a fixed acoustic center only the Max
Coherence is operative. Approve its use by clicking on OK
and the program will automatically determine for you the best
focus point for each of the beams.
Auto-Focus will also warn you if the location you have chosen
for the steerable array isn't ideal.
You can override this warning if you want and the program will
still attempt to properly focus all the beams. You may, however,
want to try moving the array up or down to see if you can find
a better location for the Iconyx array or use more or fewer
beams to see it you can eliminate this warning prompt.
So far we have been exploring the capabilities of BeamWare and not focusing on practical applications. The graphic below shows a typi-
cal setup for a small room (50 feet deep) with the bottom of the array placed 6.46 feet above floor level, approximately the height of an
array mounted on a subwoofer sitting on a stage or at altar level. Note that a single ICL-F array was selected and an opening
angle of 30° chosen.
A center frequency of 3150 Hz was also selected for the simulation as it better depicts what the listeners will be hearing than the lower
1000 Hz center frequency we used in previous simulations.
