ART300A

Active Speaker System

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.

Safety First!

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.

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.
