User manual MACKIE ART500A DATASHEET

[. . . ] The HF section uses a Polynomial CD horn loaded to a 2" exit titanium compression driver and new technology, ring-mode suppression design to deliver controlled coverage at the highest sonic purity. The CD horn is a part of the molded enclosure. Two discrete power amplifiers and an electronic crossover are matched to the two transducers and provide time correction, CD horn compensation, as well as peak-limiting, over-excursion and thermal protection.

The loudspeakers shall consist of a 15 inch lowfrequency, cone driver, with at least a 3 inch voice coil, and an 80° x 60° high-frequency, constantdirectivity polynomial horn with a horn-loaded, 2 inch compression driver having a titanium diaphragm and compensated for horn resonance and ringing. The drivers shall be aligned with an analog circuit and crossed over at 1. 2kHz 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 400W RMS to the low-frequency driver and 100W RMS to the highfrequency 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 overheating, over-excursion, overloads, short circuits and extreme operating temperatures. An indicator light shall illuminate when any aspect of the protection circuit engages. The integrated mic/line input shall be actively balanced, may also accept an unbalanced input, and shall be paralleled to an output. 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 +4dB at 65Hz and +4dB at 12kHz.
