Mackie Professional Audio
HDA, High-Def. Powered Loudpseakers

Powerful Class-D Fast Recovery™ Amplification
HDAs are bi-amplified, delivering 1200W of peak system power: 500W RMS for LF, 100W RMS for HF. They use Class-D amplifiers, which are ultra-efficient and cool running, providing all the power needed to push the high-output drivers in a design that is lightweight. Mackie amplifiers incorporate our Fast Recovery™ circuitry, which helps to smooth nasty distortion when things get pushed too hard. Power runs are industry standard Neutrik® PowerCons with an AC pass-through, reducing clutter and confusion.

EAW Inside
Every Mackie loudspeaker features custom-designed drivers perfectly suited for the task at hand. HDA features three drivers, each high-output and designed specifically for use in an HDA system. The HDA features a 12" neodymium woofer with a 3" voice coil to handle the 500W delivered by the dedicated LF amplifier. Designed by EAW, this LF driver delivers deep, rich bass performance in a lightweight neodymium design built to last until the wee hours of the morning.

For the dual 1.7" HF compression drivers, we turned to the experts at Beyma®, well-known for their high-performance drivers. Built using heat-treated titanium diaphragms, the dual HF drivers deliver pristine high-frequencies and are mounted into a custom-designed dual exit horn, providing precise coverage that’s as wide as it is awesome.

HDA is a perfectly tuned system that is truly greater than the sum of its parts. Collaboration with the line array experts at Eastern Acoustic Works (EAW) made this possible. The engineering team at EAW not only provided acoustical and mechanical design right from the start, they then fine-tuned the system for complete optimization, ensuring maximum efficiency and performance. After all, EAW knows arrays and we like EAW. They always bring the best side dish to a potluck.

HD Digital Processing
Part of Mackie’s HD Series, HDA incorporates our proven HD Digital Processing. Even the most expensive loudspeakers on the market have inherent sonic issues that arise from the very nature of loudspeaker design. Horn-loaded drivers tend to have a “honkiness” to them and there are physical resonances in the upper range of cone drivers that can sound nasty.

Introducing Mackie High-Definition Audio Processing. The key to high-definition live sound is the detailed measurement and analysis of the inherent problems of horns and woofers. After that, the creation and application of some seriously NASA-esque (and patented) acoustic correction algorithms work to correct these very issues. Vocals become clean and intelligible and the highs are smooth and never harsh. The resulting experience is not only high-definition, it is truly a moment of clarity for anyone within earshot.

Simple, but Powerful Array Voicing
Proper array voicing is probably one of the most time-consuming and difficult tasks related to arrays. HDA makes voicing easier than ever with a three-position voicing switch, allowing for easy customization of each box in the array. These optimized settings tailor the low frequency output to the number of boxes in use, keeping the voicing consistent as more boxes are added. If you’re only using one or two boxes, you can simply set the switch to the corresponding position and call it a day. For rigs with three or more boxes, use the 3-4 setting and, for larger venues, use the long throw setting to help your top box reach the cheap seats by compensating for high frequency air loss. More advanced users can integrate EAW’s Resolution software, which calculates array placement and flybar pickpoints, showing you the resulting coverage for the venue. Array voicing has never been easier or more predictable.

Professional Grade Cabinet
The HDA is meant to last, with a robust all-wood enclosure built using 15mm birch plywood. But it’s also built for rigging, featuring proven EAW rigging channels for easy setup and teardown of a vertical array. The dedicated flybar option allows for easy raising and lowering of the entire system. It also has four integral rigging points, or you can pole mount a couple on top of a subwoofer using the dual angle pole cup…the choice is yours, but know that HDA is “Built-Like-A-Tank” and ready for the road. Toughness is great, but we know that a speaker should also look good and have features that make it easily fit into any venue. That’s why the HDA has a sleek, professional look and Mackie’s trademark blue light on the front (yes, you can turn it off for stealthy applications). Dang, we thought of everything.
