The AM604 is an extended range mid/high system which has  
been developed specifically for large scale install applications  
such as arenas and stadia. It can be used in either a bi-amplified  
or optional 2-way passive configuration. As a stand-alone  
system it provides exceptional intelligibility over its uniform 60˚  
x 40˚ coverage pattern. For full-range music reproduction, it  
can also be used in conjunction with the AS118 low-frequency  
loudspeaker.
