The ART500A is a full-range two-way
professional active speaker system that
combines high-power, wide bandwidth, and
the reduced weight of a special hybrid
construction for fixed-installation systems. The
15" low-frequency transducer, in combination
with a 2" exit titanium compression driver
coupled to an integral 80º x 60º 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, and a rotary
The two built-in power amplifiers provide
400W for the LF driver and 100W for the HF
driver. The enclosure is constructed of high-
strength polypropylene with two internal
16mm thick multilayer wood panels. It has six
M10 threaded inserts, and an integral locking
1-3/8" socket in the bottom for mounting on a
standard speaker stand.
Before connecting and using the
equipment, please read this Quick-Start Guide
carefully and keep it for future reference.
WARNING! This equipment has been
designed to be installed by qualified
professionals only! There are many factors to
be considered when installing professional
sound reinforcement systems, including
mechanical and electrical considerations, as
well as acoustic coverage and performance.
Mackie Industrial strongly recommends that
this equipment be installed only by a
professional sound installer or contractor.
CAUTION: To avoid the risk of electric
shock, never allow this equipment to
be exposed to rain or dampness.
Active Speaker System
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.
