The amplified loudspeaker system shall be a self-

contained unit, housed in a reinforced polypropylene 

enclosure and consisting of the following sub-sys-

tems: (1) vented two-way loudspeaker system, (2) 

integrated power amplifiers and crossover network, 

(3) integrated mic/line input with music and voice 

equalizers.

The loudspeakers shall consist of a 12 inch low-

frequency, cone driver, and a 90° x 70° high-fre-

quency, constant-directivity polynomial horn with a 

horn-loaded, 1 inch compression driver. The drivers 

shall be aligned with an analog circuit and crossed 

over at 1.8kHz by a 4-pole network built into the 

power amplifiers. Together they shall be capable of 

producing 126dB SPL (1m, anechoic).

Two discrete amplifiers shall be provided, capable 

of continuously delivering 300W RMS to the low-

frequency driver and 60W RMS to the high-fre-

quency driver. Distortion shall be less than 0.1% 

when measured at 1kHz and 10kHz. They shall be 

equipped with a multi-function protection circuit to 

peak limit and protect the loudspeakers from over-

heating, over-excursion, short circuits and extreme 

operating temperatures. An indicator light shall illu-

minate when any aspect of the protection circuit 

engages.

The integrated mic/line input shall be actively 

balanced, may accept an unbalanced input, and shall 

be paralleled to an output. Both shall have XLR connec-

tors. The input shall have a switch to select between 

10mV mic and 775mV line levels. The unit shall be 

provided with both voice and music optimization 

equalization that can be activated with buttons on 

the rear panel. The voice equalizer shall provide +4dB 

at 3kHz and +4dB at 6kHz. The music equalizer shall 

provide +4.5dB at 65Hz and +4dB at 12kHz. A contin-

uously variable, rotary master volume control shall 

be provided.

The power supply shall be internal and connected 

to 50 or 60Hz source current through a detachable 

IEC power cord. It shall have an on/off switch, fuse 

holder and threaded grounding screw on the rear 

panel. AC voltage shall be selectable between 115 

and 230VAC. The power supply shall draw a maxi-

mum of 5A and illuminate an indicator light when on.

The reinforced polypropylene enclosure shall have 

a volume of at least 1.65 cu. ft., be trapezoidal shaped 

and equipped with a grille to protect the cone driver. 

At least four M10 threaded sockets and stand socket 

shall be molded into the cabinet for attaching mount-

ing hardware, designed for the unit and available from 

the manufacturer. The amplified loudspeaker system 

shall be a model ART300A manufactured by Mackie 

Industrial.
