Acoustic steering is a feature that allows you to guide a speaker's sound beam through the interaction
of several loudspeakers. The full potential of this technique can truly be maximized only when there is
a system that allows you to precisely and independently control each element of the array. A powerful
software that can optimize all the parameters in order to obtain the desired acoustic result is required.
With this capability, each KH7 has an onboard DSP designed to load FIR filters to achieve the best
and most accurate steering results. FIR coefficients can be easily calculated with EASE Focus, the
most accurate acoustic simulation software available in the market. Based on input data describing
location geometry and sound sources, the software computes optimal filter transfer functions that can
be automatically converted to FIR filters.
EASE Focus software and its User Guide can be downloaded from the AFMG website: focus.afmg.eu
