Our HR824mk2 and HR624mk2 high-resolution Active studio reference monitors represent the evolution of revolutionary thinking. Our engineers, joined by audio gurus from EAW, worked hard to conceive of a way to preserve the all-important character of the original HR, while delivering performance--as well as appearance--that's better than ever. And even moreso than the original HR824 and HR624, which were designed apart from each other, the HR824mk2 and HR624mk2 are part of the same family, true siblings in design and sound. Sharing the same engineering, they are created to work together, whether in surround systems, or as part of complementary monitoring setups in different sized rooms.
The new one-piece cast aluminum Zero Edge Baffle features precisely engineered curvature that minimizes diffraction for a crystal clear image of your mix, and effectively controls sound waves so you get detailed lows, full, articulate mids, and shimmering highs. The integrated Optimized Waveguide accurately and efficiently controls dispersion characteristics of the sound on and off axis, resulting in a wide sweet spot with smooth transitions from lows to highs. More inert than a wood or plastic baffle, the Zero Edge Baffle's cast metal surface reduces surface vibrations during playback, thereby minimizing distortion to the sound's waveforms; the result is improved time-domain characteristics, which equates to dramatically enhanced depth of field.
Thanks to the design of the Zero Edge Baffle, the HRmk2's imaging is stunningly accurate, with wide, even dispersion, and three-dimensional sound, delivering a much broader sweet spot than any other studio monitor on the market--so broad, in fact, that we like to call it a sweet zone.
The HRmk2 Series monitors are a true Active design, meaning they contain separate onboard amplifiers for each driver, plus onboard active crossovers and time-correction circuitry, which helps ensure highs and lows reach your ears at the same time. The HRmk2s also have protection circuitry built in to protect from damaging input levels. With the same class A/B amplifier design as the original HR Series, the HRmk2s retain the much-loved character of our classic monitor, and carry on the Acoustic Space circuitry of the classic HRs, which allows you to tune the monitors to your room.
Designed into the heart of the amplifier circuits are EQ and filter 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 your studio. Before assembly, we first hand-trim the amplifiers to exactly match the amplifiers in our Golden Reference Unit. (See "Unparalleled Quality" for more on the Golden Reference Unit.) During final assembly and testing, the amplifiers are voiced to match the rest of the components in the entire monitor system; they're hand-trimmed to compensate for very slight manufacturing tolerances between the drivers. This meticulous process results in each monitor being within exacting references of the Golden Reference Unit.
Each HRmk2 monitor features a high-precision, low-distortion woofer--8.75-inch for the HR824mk2 and 6.7-inch for the HR624mk2--and a 1-inch ferrofluid cooled titanium dome tweeter. An exhaustive process, the selection of the new HRmk2 drivers consumed considerable engineering resources. Our team spent countless hours in their quest to find drivers that met our stringent criteria, including the ability to be manufactured in volume with virtually no variability between units, the ability to produce the desired frequency response, and the ability to meet the tight price goals that allow us to make our monitors affordable. After having rejected multiple candidates, the team eventually narrowed down the field. With further engineering input, we sourced drivers that met our standards, and successfully managed to fine-tune a system that delivers unparalleled results.
The HRmk2 monitors feature a wood cabinet, with custom internal bracing to increase its strength and rigidity in desired locations. To absorb internal reflections and dampen standing waves inside the cabinet, an open-cell adiabatic foam material is placed strategically inside the box. While an all-metal cabinet had been considered as a potential design strategy, in the end 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 Baffle adds that unquantifiable "bit of warmth," producing sound that's true--and never lifeless.
Attention To Detail
To say we here at Mackie are detail-oriented is an understatement. We obsessed over every last detail on the HRmk2 Series--from the color 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 settings from home theatres to gaming rooms to studios, we opted for a look that would be universally appealing. The high-gloss, piano black finish of the cabinet complements the deep charcoal grey of the Zero Edge Baffle, and gives the HRmk2 a modern, professional look that suits just about any environment. All HRmk2s ship with peelable, protective film on each side to ensure that they look as brilliant 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 the brightness is just right, too. The light shines bright enough so you can see it just fine in a well-lit room, and in a dark environment, it won't distract--or blind you. We saved the red for when you're overdoing it--you'll see the scarlet HRmk2 overload LED when your input levels are too high.
Rotating Mackie Logo
Along with Acoustic Space Controls that allow you to adjust low frequency response to compensate for placement next to the wall, in corners, or in the center of a room, the HRmk2s come with other features that enable versatile setup. Due to their ultra-wide sweet zone, our HRmk2 monitors can be oriented vertically or horizontally, so we made our Mackie logo rotate-able. (Yes, we thought of everything.) No matter which way you orient your HRmk2s, they're always right-side up! Each HRmk2 also supplies Omnimount capability, so you aren't forced to screw into--and damage--the enclosure's surface in order to mount to the wall or from the ceiling.
