Mackie HD1531 Spec Sheet - Page 1

HD1531 HIGH-DEFINITIONPOWERED LOUDSPEAKER HD1531 The HD1531 3-Way High-Definition Powered Loudspeaker delivers 1800W of peak system power via Class-D Fast Recovery™ amplification. Class-D amp design delivers up to 95% efficiency and, along with the lightweight switch-mode power supply, drastically reduces loudspeaker weight. Mackie High-Definition Audio Processing provides unmatched sonic accuracy and clarity. Mackie Active technology includes a precision 3-way crossover, transducer time alignment, and phase correction. Plus, patented acoustic correction algorithms harness the power of proprietary measurement tools that identify sonic anomalies that are inherent to all horn-loaded systems. Extremely complex algorithms are then applied to the HD1531 to counter these anomalies; this improves vocal intelligibility while removing high frequency discord. EAW custom-designed HD Series transducers maximize efficiency and performance when matched with the system's internal amps. The 15-inch woofer uses a neodymium magnet for reduced weight, and the 3-inch voice coil dissipates heat extremely well. The 1.75-inch compression driver and 6-inch midrange transducer are loaded into Mackie's wide-dispersion WaveFront™ system, which ensures optimum intelligibility for every seat in the house. The integrated 3-band contour EQ with a sweepable mid allows the user to custom-tailor system tone for their application or correct for common room anomalies. A bypass switch provides easy implementation of a pre-set EQ. The 15mm birch plywood enclosure is rugged and ready for install using the 12 integral fly points. Standard M-10 eyebolts allow the HD1531 to be flown both vertically and horizontally. The look of the HD1531 is understated and the front LED can be defeated for maximum stealth. The lightweight design of the HD1531 allows for pole-mounting on a tripod stand or atop a subwoofer. APPLICATIONS Small to mid-size club/band PA systems, houses of worship, DJs, rehearsal spaces, gymnasiums, banquet halls, A/V rentals and many, many more.
