ART300A Service Manual
Overview
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 fi xed-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 amplifi ers
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.
