Amplifiers

• The HRmk2 Series monitors are a true Active design, meaningthey contain separate onboard amplifiers for each driver, plus onboard activecrossovers and time-correction circuitry, which helps ensure highs and lowsreach your ears at the same time. The HRmk2s also have protection circuitrybuilt in to protect from damaging input levels. With the same class A/Bamplifier design as the original HR Series, the HRmk2s retain the much-lovedcharacter of our classic monitor, and carry on the Acoustic Space circuitry ofthe classic HRs, which allows you to tune the monitors to your room.
• Designed into the heart of the amplifier circuits are EQ andfilter sections that allow each amplifier to be precisely factory-tuned,ensuring that what we designed in our labs is what you end up with in yourstudio. Before assembly, we first hand-trim the amplifiers to exactly match theamplifiers in our Golden Reference Unit. (See "Unparalleled Quality"for more on the Golden Reference Unit.) During final assembly and testing, theamplifiers are voiced to match the rest of the components in the entire monitorsystem; they’re hand-trimmed to compensate for very slight manufacturing tolerancesbetween the drivers. This meticulous process results in each monitor beingwithin exacting references of the Golden Reference Unit.

Woofer/Tweeter Selection

• Each HRmk2 monitor features a high-precision, low-distortionwoofer—8.75-inch for the HR824mk2 and 6.7-inch for the HR624mk2—and a 1-inchferrofluid cooled titanium dome tweeter. An exhaustive process, the selectionof the new HRmk2 drivers consumed considerable engineering resources. Our teamspent countless hours in their quest to find drivers that met our stringentcriteria, including the ability to be manufactured in volume with virtually novariability between units, the ability to produce the desired frequencyresponse, and the ability to meet the tight price goals that allow us to make ourmonitors affordable.
• After having rejected multiple candidates, the teameventually narrowed down the field. With further engineering input, we sourceddrivers that met our standards, and successfully managed to fine-tune a systemthat delivers unparalleled results.

Cabinet Design

• The HRmk2 monitors feature a wood cabinet, with custom internalbracing to increase its strength and rigidity in desired locations. To absorbinternal reflections and dampen standing waves inside the cabinet, an open-celladiabatic foam material is placed strategically inside the box. While anall-metal cabinet had been considered as a potential design strategy, in theend our design team used their ears to make their choice of cabinet material.
• And what they heard from an all-metal cabinet was a sound that was accurate,but overly sterile. Combining a wood cabinet with our metal Zero Edge Baffleadds that unquantifiable “bit of warmth,” producing sound that’s true—and neverlifeless.

To say we here at Mackie are detail-oriented is anunderstatement. We obsessed over every last detail on the HRmk2 Series—from thecolor and finish, to the power indicators and even the vents in the heat sink.

Paint it Black

• With the potential for the speakers to be used in settingsfrom home theatres to gaming rooms to studios, we opted for a look that wouldbe universally appealing. The high-gloss, piano black finish of the cabinetcomplements the deep charcoal grey of the Zero Edge Baffle, and gives the HRmk2a modern, professional look that suits just about any environment. All HRmk2sship with peelable, protective film on each side to ensure that they look asbrilliant in your studio as they do when they leave the factory.

LED Power & Overload

• Our LED power indicator is a tasty shade of white—a cool,refreshing change from your typical red. We took care to make sure thebrightness is just right, too. The light shines bright enough so you can see itjust fine in a well-lit room, and in a dark environment, it won’t distract—orblind you. We saved the red for when you’re overdoing it—you’ll see the scarletHRmk2 overload LED when your input levels are too high.
