Exposure to extremely high noise
levels may cause permanent hearing
loss. Individuals vary considerably in
susceptibility to noise-induced hearing loss, but nearly everyone will lose
some hearing if exposed to sufficiently
intense noise for a period of time. The U.S.
Government’s Occupational Safety and Health Administration (OSHA) has specified the permissible
noise level exposures shown in this chart.
Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example
8 90 Duo in small club

1.5 102
1 105 Patrice screaming at Ron about deadlines
0.5 110
0.25 or less 115 Loudest parts at a rock concert
According to OSHA, any exposure in excess of
these permissible limits could result in some hearing loss. To ensure against potentially dangerous
exposure to high sound-pressure levels, it is recommended that all persons exposed to equipment
capable of producing these levels use hearing protectors while this unit is in operation. Ear plugs or
protectors in the ear canals or over the ears must
be worn when operating this amplification system
in order to prevent a permanent hearing loss if
exposure is in excess of the limits set forth here.

INTRODUCTION
Thank you for choosing Mackie Designs’
HR624 Studio Monitors. 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!
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 HR624. And we
invested in some advanced (and need we say
expensive) measurement and analysis tools for
the design team to use.
The result? The HR624 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!
What are they? The Advantages...
The HR624 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 HR624.
• 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 52Hz 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.
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 6.7-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 9-inch elliptical flat piston passive radiator in the back.
The high-frequency driver is mounted on a
massive, acoustically non-resonant die-cast zinc
QUICK START
We realize that you can’t
wait to hook up your new
Mackie Designs HR624
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.
Make sure the Voltage
Selector Switch
bottom of the cabinet is set
to the correct voltage setting
for your AC Mains supply.
Each of the HR624 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 mute switch
on the front panel to its
standby position (in). 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 HR624, 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 set-

on the
exponential waveguide which results in wide,
controlled dispersion of high-frequency sounds.
The unique passive radiator design provides a
smooth response down to 49Hz — 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.
The Cabinet...
The cabinet is made of black oak veneered
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.
Power Amplifiers...
The low-frequency amplifier produces up to
100 watts continuous before clipping, while the
high-frequency amplifier produces up to 40 watts
continuous.

AN EXTREMELY IMPORTANT NOTE
ON HR624 BASS RESPONSE AND
YOUR CONTROL ROOM.
Your new HR624s achieve
their best bass response in
a room that’s optimized for
bass reproduction. A lot of
factors can conspire to
thwart the HR624s’ extended low frequency —
including room shape, room volume and
acoustical treatment.
This is not a cop-out or an apology. It’s plain
old physics in action. Luckily we’ve armed you
with some compensating controls which you
can use to optimize the frequency response of
the speakers in your particular room. Consider
the following:
The ACOUSTIC SPACE switch
must be set correctly.
When you put your HR624s in a corner or
up against walls, their bass characteristics
change. Adjust the
switch setting accordingly to avoid muddy or
exaggerated low frequency response.
Feel free to experiment.
In many respects, every room is unique in
terms of its acoustics.
Even after you’ve read about how to set the
HR624’s rear panel switches, try other settings
to see if your particular room environment
requires different adjustments.
And, even after you’ve placed your monitors
where you think they’ll sound best, try moving
them around. You might be pleasantly surprised.
Finally, keep an open mind about
improving your room’s acoustics
and bass-handling ability.
Nobody likes to buy a new set of monitor
speakers and then be told that they should
spend extra bucks on bass traps or a remodeling
ACOUSTIC SPACE
job. But the simple fact is, “standard” rooms,
i.e. rectangular rooms in conventional business
or residential structures, are rarely if ever
conducive to optimal low bass reproduction
without some modifications.
Luckily, there are plenty of options short of
building a new control room, many of which
are covered in this manual.
Additional Tidbits of Wisdom
• When you shut down your equipment, turn
off the HR624 studio monitors first to
prevent thumps and other noises generated
by any upstream equipment from coming
out the speakers. When powering up, turn
on the monitors last.
• Save the shipping box! You may need it
someday, and you don’t want to have to pay
for another one.
• Save your sales receipt in a safe place.
• Also record all HR624 serial numbers in the
space provided on the inside front cover,
along with where and when you bought them.
Placement
The HR624s were designed to be placed in a
vertical position. If you find it necessary to
place the speakers in a horizontal position (on
their sides), place them so that the woofers are
toward the inside; that is, so the woofers are
closest to each other. This provides the best
low-frequency summing and overall imaging.
Note: The Mackie logo can be rotated 90º
so that it is oriented correctly when placing
the speakers on their sides. Gently pull out
on the Mackie emblem, rotate it, and push
it back into place.
