Quick-Start Guide  
The ART300A is a full-range two-way  
professional active speaker system that  
combines high power and wide bandwidth in  
a light-weight enclosure for fixed-installation  
systems. The 12" low-frequency transducer, in  
combination with a 1" compression driver  
coupled to an integral 90º x 70º constant  
directivity polynomial horn, form an extremely  
powerful package for any small to medium-  
sized sound reinforcement application.  
It features a balanced XLR input with a  
Mic/Line switch and a paralleled balanced  
XLR output for cascading multiple speakers.  
Rear panel controls also include Music and  
Voice equalization switches, a rotary volume  
control, and an input limiter.  
The two built-in power amplifiers provide  
300W for the LF driver and 60W for the HF  
driver. The enclosure is constructed of high-  
strength polypropylene, with M10 threaded  
inserts on all four sides for rigging, and an  
integral locking 1-3/8" socket in the bottom  
for mounting on a standard speaker stand.
