9.3 aRRaY ConfIGURaTIons

In this configuration the cluster behaves as a vertical line array. The coverage along the vertical axis 
depends on the number of speakers flown and is digitally adjustable via software.

FLOOD

Coverage 100°

SPOT
Coverage is the number of speakers 
dependent and digitally adjustable.
