ART400A Two-Way Active Speaker System

Architects’ & Engineers’ Specifications

ART400A

The amplified loudspeaker system shall be a self-contained unit, housed in a reinforced polypro- pylene enclosure and consisting of the following sub-systems: (1) vented two-way loudspeaker system, (2) integrated power amplifiers and cross- over network, (3) integrated mic/line input with music and voice equalizers.

The loudspeakers shall consist of a 15 inch low-frequency, cone driver with at least a 3 inch voice coil and a 80° x 60° high-frequency, constant- directivity polynomial horn and horn-loaded, 2 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 125dB SPL (1m, anechoic).

Two discrete amplifiers shall be provided, capable of continuously delivering 300W RMS to the low-fre- quency driver and 50W RMS to the high-frequency driver. Distortion shall be less than 0.1% when mea- sured at 1kHz and 10kHz. They shall be equipped with a multi-function protection circuit to peak limit and protect the loudspeakers from overheating and over- excursion, overloads, short circuits and extreme oper- ating temperatures. An indicator light shall illuminate 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 connectors. 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 optimi- zation equalization that can be activated with but- tons on the rear panel. The voice equalizer shall pro- vide +4dB at 3kHz and +4db at 6kHz. The music equalizer shall provide +4.3dB at 65Hz and +4dB at 12kHz. A continuously variable, rotary master volume control shall be provided.

The power supply shall be internal and con- nected to 50 or 60Hz source current through a detachable IEC power cord and shall have an IEC socket for mains power loop-through. It shall have an on/off switch, fuse holder and threaded ground- ing screw on the rear panel. AC voltage shall be selectable between 115 and 230VAC. The power supply shall draw a maximum of 5A and illuminate an indicator light when on.

The reinforced polypropylene enclosure shall have a volume of at least 2.64 cu. ft., be trapezoidal shaped and equipped with a grille to protect the cone driver. At least four M10 and two M8 threaded sockets and stand socket shall be molded into the cabinet for attaching mounting hardware, designed for the unit and available from the manufacturer. The amplified loudspeaker system shall be a model ART400A manufactured by Mackie Industrial.
