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.
