Architects' & Engineers' Specifications
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.
