Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
MR5
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially danger
ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres
sure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here.

INTRODUCTION
MR5
Thank you for choosing the MR5 Mackie Reference
Studio
Monitors. Just as we revolutionized the studio
monitor market with our flagship HR824 Studio Monitor,
we have done it again with the most affordable precision
active studio monitors ever made. The MR5 features
design elements shared by our HR MK2 Series high resolution studio monitors, providing a level of performance
never before available at this price.
• The connecting wires 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 driv
ers are optimized electronically, as well as physically, so the amplitude response is unity and the
phase difference is minimal.
-
Investments in Excellence...
The MR5s were designed by our expert loudspeaker
and transducer engineering teams at Mackie and EAW.
These compact studio monitors can be used in a variety
of applications, including small project studios, surround
sound editing, home theater playback, and desktop
audio workstations (DAWs).
High-frequency and low-frequency switches are provided on the rear panel to adjust the sound of the monitors to the characteristics of the room. Three types of
input connectors are provided, XLR, 1/4-inch, and RCA,
to interface with virtually any application you may have.
The result? The MR5 Studio Monitors are extremely accurate and versatile, 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 MR5 Studio Monitors are
active monitors employing a bass reflex (ported) design
for an extended low-frequency response. 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 MR5.
•
The crossover point is designed so that the high- and
low-frequency drivers are fed only the frequencies
they are best able to reproduce.
two-way, bi-amplified,
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 MR5s feature a 5.25-inch high-precision, low-distortion woofer and a 1-inch high-resolution
The high-frequency driver is mounted on a molded
baffle/waveguide, which reduces diffraction and results
in wide, controlled
This widens the “sweet spot” and improves the time
domain characteristics of the system.
dispersion of high-frequency sounds.
tweeter.
The Cabinet...
The cabinet is made of MDF with a matte-black finish.
Internal bracing 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 Ampliers...
The low-frequency amplifier produces up to 55 watts
continuous before clipping, while the high-frequency
amplifier produces up to 30 watts continuous. Both amplifiers are Class A/B with power MOSFET outputs and
active protection circuits.
• 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 re
sponses are individually hand-trimmed to compensate for typical manufacturing tolerances between
the drivers and produce a smooth frequency
response from 60 Hz to 20 kHz.

QUICK START
Owner’s Manual
AN EXTREMELY IMPORTANT NOTE
We realize that you can’t wait to hook
up your new Mackie MR5 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.
1. Turn the INPUT LEVEL [2] control on the back of the
cabinet down (fully counterclockwise) before turning
on the monitor for the first time.
2. Set the power switch [5] on the back panel off. This will
prevent you from accidentally connecting a hot signal
source to the monitor and getting a rude surprise.
3. Leave the High Freq [3] and Low Freq [4] Filter
switches at their Normal positions.
4. Connect the line-level monitor signal from your mixer,
preamp, or other signal source to the INPUT [1] jack
on the MR5 Studio Monitor (1⁄4-inch PHONE, XLR, or
RCA).
5. Connect the supplied AC power cord to the IEC socket
[6] on the back of the monitor. Plug the other end into
an AC outlet properly configured with the voltage corresponding to the markings next to the IEC socket.
6. Start your signal source (tape deck, CD, DAW, or
whatever), but leave the master volume control on your
mixer or preamp down.
7. Turn on the power switch [5] on the MR5. The power
LED [8] on the front panel will illuminate.
6. Slowly turn up the INPUT LEVEL [2] control on the
back of the monitor to its fully clockwise position
(MAX).
7. Adjust the master volume on your mixer or preamp to
a comfortably loud listening level. If the MR5 gets loud
really fast, turn down the INPUT LEVEL control to its
center position (12 o’clock) to provide more volume
control on your mixer or preamp.
Enjoy the silky smooth highs and authoritative, com
manding lows of the MR5. Then read the rest of this
manual.

ON MR5 BASS RESPONSE AND
YOUR CONTROL ROOM.
Your new MR5s achieve their best bass
response in a room that’s optimized
for bass reproduction. A lot of fac
tors can conspire to thwart the MR5s’
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 that you can use to optimize the
frequency response of the speakers in your particular
room. Consider the following:
Low-Frequency Response
When you put your MR5s in a corner or up against
walls, their bass characteristics change. The apparent
loudness of the low frequencies increases when the
monitors are placed close to a wall, and even more so
when they are placed in a corner.
If you have placed the monitors away from the walls
and corners and you would like to hear a little more
bass, try setting the LOW FREQ FILTER [4] switch to
the +2 dB position to provide a gentle boost to the low
frequencies (below 100 Hz). If it’s still not enough bass,
try the +4 dB position to provide a little more bass boost.
High-Frequency Response
The MR5s are designed to provide a smooth frequency
response throughout the mid and high range. Nevertheless, you may decide that you need a little more or a
little less high frequencies in your monitors while you
are mixing. The HIGH FREQ FILTER [3] switch provides
a gentle boost or cut in the frequencies above 5 kHz.
Remember that boosting the high frequencies in the
monitors can result in a duller mix, while reducing the
high frequencies can result in a brighter overall mix.

Additional Tidbits of Wisdom
• Never listen to loud music for prolonged periods. Please
see the Safety Instructions on page 2 for information on
hearing protection.
When you shut down your equipment, turn off the MR5
•
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 MR5 serial numbers in the space provid-
•
ed on page 3, along with where and when you bought them.
