We realize that monitors are a critically important tool whether your application is studio recording, audio/video post production, hi-fi, or home theater. Knowing this, Greg Mackie had a simple mandate: Design a reference monitor with a degree of accuracy and versatility unmatched by any other in its size and price category -- or any size and price category for that matter. The mandate was simple, but accomplishing it was another story! In short, all the complex interconnected components in the system are designed to work in harmony with each other to produce the best possible sound. The Transducers... The monitors feature an 8.75-inch die-cast magnesium frame woofer and a 1-inch viscous edge-damped aluminum-alloy dome tweeter on the front, and a 6-inch x 12-inch elliptical flat piston passive radiator in the back. The high-frequency driver is mounted on a massive, acoustically non-resonant die-cast zinc exponential waveguide which results in wide, controlled dispersion of high-frequency sounds. The unique passive radiator design provides a smooth response down to 39Hz -- an astounding accomplishment for a cabinet of this size! And since the radiator is producing most of the sound at the lowest frequencies, there is very little distortion from the woofer because its cone movement is minimal at those frequencies. Investments in Excellence... To accomplish the task at hand, Greg and the New Product Development team realized that a commitment was required in terms of new resources and new equipment. So we recruited some of the best speaker and acoustic engineers in the industry to assist in the design of the HR824. And we invested in some advanced (and need we say expensive) measurement and analysis tools for the design team to use. The result? The HR824 Studio Monitors are extremely accurate and versatile, loaded with unique controls that allow you to fine-tune the sound to match your individual environment precisely. You're gonna love these! The Cabinet... The cabinet is made of high-density MDF wood. An internal "H" brace further increases the strength and rigidity (stiffness) of the box. An open-cell adiabatic foam material fills the inside of the box to absorb internal reflections and dampen standing waves. What are they? The Advantages... The HR824 Studio Monitors are high-resolution, two-way, bi-amplified, active monitors employing a 6th-order Butterworth system with a built-in rear-firing mass-loaded passive radiator. Whew! There are many benefits to integrating an active crossover, power amplifiers, and drivers into a single cabinet, and we've taken full advantage of these benefits in the design of the HR824. · The crossover point is designed so that the high and low frequency drivers are fed only the frequencies they are best able to reproduce. · The amplifiers are designed to provide maximum acoustic output from the speakers, yet minimize the danger of speaker damage due to overdriving. · In addition, the amplifiers' gain and frequency responses are individually hand-trimmed to compensate for typical manufacturing tolerances between the drivers and produce a smooth frequency response from 39Hz to 20kHz (±1.5 dB). · The connecting wire between the amplifier outputs and the drivers are kept to an absolute minimum, so the damping factor of the amplifier isn't compromised by the resistance of long speaker cables. · The acoustic sum of the outputs from the two drivers are optimized electronically, as well as physically, so the amplitude response is unity and the phase difference is minimal. FR Series Power Amplifiers... What better way to power the loudspeakers than with our acclaimed FR Series "Fast Recovery" power amplifiers. Our Fast Recovery design uses low negative feedback, yet allows the amplifiers to maintain low distortion and stability even when driven into clipping. The low-frequency amplifier produces up to 150 watts continuous (350 watts peak) before clipping, while the high-frequency amplifier produces up to 100 watts continuous (210 watts peak).

We realize that you can't wait to hook up your new Mackie Designs HR824 High Resolution Studio Monitors and try them out. Nevertheless, please take the time to read this page NOW, and the rest can wait until you're good and ready. Each of the HR824 cabinets has its own builtin power amplifiers. That's right, two amplifiers per speaker cabinet; one for the high-frequency tweeter and one for the low-frequency woofer. You should turn the INPUT SENSITIVITY control on the back of the cabinet down (fully counterclockwise) before turning on the Studio Monitors for the first time. Also be sure to set the power switch on the front panel to its standby position (down). This will prevent you from accidentally connecting a hot signal source to the monitors and getting a rude surprise. There are a number of other settings you can make on the back of the HR824, and you can look at the graphic instructions relating to each of them on the back of the cabinet (or wait until you read about them later on in this manual so you really know what they do). For now, just leave them at the factory default settings (ACOUSTIC SPACE = WHOLE; LOW FREQ = 37Hz; HIGH FREQ = 0), except for the POWER MODE switch. Be sure it is set to the STANDBY position. 4 1. Connect the line-level monitor signal from your mixer (or other signal source) to the SIGNAL INPUT jack on the HR824 Studio Monitor (1/4-inch TRS, XLR, or RCA). 2. Connect the supplied AC power cord to the IEC socket on the back of the monitor. Plug the other end into an AC outlet properly configured with the correct voltage for your particular model. 3. Set the POWER MODE switch on the rear panel to the ON position. With the power switch on the front panel in the down position, the power amplifier is in Standby mode. 4. Start your signal source (tape deck, CD, DAW, or whatever), but leave the master level control on your mixer down. 5. Set the power switch on the front of the HR824 to the ON position. The red PWR LED will turn on. 6. Slowly turn up the INPUT SENSITIVITY control on the back of the monitor to its fully clockwise position (NORMAL). 7. Adjust the master volume on your mixer to a comfortably loud listening level. Enjoy the silky smooth highs and authoritative, commanding lows of the HR824.
