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.

Safety First!

Quick-Start Guide
1. Never install, connect, or disconnect
the unit with the power supply on.
2. Before powering up the speaker,
make sure the voltage select switch
corresponds to the AC Voltage supply.
3. Make sure the safety ground on the
power cord is properly grounded.
4. To prevent the risk of electric shock,
never open the unit. There are no
user serviceable parts inside.
5. To ensure normal cooling of the
amplifier, make sure the unit is well-
ventilated. Avoid exposure to direct
sunlight or proximity to any heat
source, dust, or dampness.
