INTRODUCTION
Thank you for choosing the MR8 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 MR8 features
design elements shared by our HR MK2 Series high reso-
lution 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 compro-
mised by the resistance of long speaker cables.
The acoustic sum of the outputs from the two driv-
ers are optimized electronically, as well as physi-
cally, 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.
Investments in Excellence...
The MR8s 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).
The Transducers...
The MR8s feature an 8-inch high-precision, low-dis-
tortion woofer and a 1-inch high-resolution tweeter.
High-frequency and low-frequency switches are pro-
vided on the rear panel to adjust the sound of the moni-
tors 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 high-frequency driver is mounted on a molded
baffle/waveguide, which reduces diffraction and results
in wide, controlled dispersion of high-frequency sounds.
This widens the “sweet spot” and improves the time
domain characteristics of the system.
The result? The MR8 Studio Monitors are extremely ac-
curate and versatile, with unique controls that allow you
to fine-tune the sound to match your individual environ-
ment precisely. You’re gonna love these!
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 mate-
rial fills the inside of the box to absorb internal reflec-
tions and dampen standing waves.
What are they? The Advantages...
The MR8 Studio Monitors are two-way, bi-amplified,
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 MR8.
Power Amplifiers...
The low-frequency amplifier produces up to 100 watts
continuous before clipping, while the high-frequency
amplifier produces up to 50 watts continuous. Both am-
plifiers are Class A/B with active protection circuits.
•
•
•
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 re-
sponses are individually hand-trimmed to compen-
sate for typical manufacturing tolerances between
the drivers and produce a smooth frequency
response from 40 Hz to 20 kHz.

AN EXTREMELY IMPORTANT NOTE
ON MR8 BASS RESPONSE AND
YOUR CONTROL ROOM.
QUICK START
We realize that you can’t wait to hook
up your new Mackie MR8 Studio
Monitors and try them out. Neverthe-
less, please take the time to read this
page NOW, and the rest can wait until
you’re good and ready.
Your new MR8s achieve their best bass
response in a room that’s optimized
for bass reproduction. A lot of fac-
tors can conspire to thwart the MR8s’
extended low frequency — including
room shape, room volume and acoustical treatment.
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.
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:
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 MR8 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 cor-
responding 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 MR8. The power
LED [8] on the front panel will illuminate.
Low-Frequency Response
When you put your MR8s 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.
8. Slowly turn up the INPUT LEVEL [2] control on the
back of the monitor to its fully clockwise position
(MAX).
9. Adjust the master volume on your mixer or preamp to
a comfortably loud listening level. If the MR8 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.
High-Frequency Response
The MR8s are designed to provide a smooth frequency
response throughout the mid and high range. Neverthe-
less, 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.
Enjoy the silky smooth highs and authoritative, com-
manding lows of the MR8. Then read the rest of this
manual.
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 MR8
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.
• Save your sales receipt in a safe place.
•
Also record all MR8 serial numbers in the space provid-
ed on page 3, along with where and when you bought them.

Owner’s Manual
REAR PANEL DESCRIPTION
This is where you connect your signal to the monitor,
ꢀ. INPUT LEVEL
and make adjustments to the frequency response of
the speakers to match the monitor’s location and your
room’s environment.
The MR8 expects a line-level signal at its input. Use
this control to adjust the sensitivity of the input section
according to the signal strength at its input.
1. SIGNAL INPUTS
• The MR8 is designed to operate with a +4 dBu signal
when the INPUT LEVEL control is in the MAX position
(in other words, wide open).
• Refer to the QUICK START section on page 5 for the
level-setting procedure.
There are three types of input connectors: XLR (bal-
anced), 1/4-inch (balanced), and RCA (unbalanced).
Since all three of them are connected together electri-
cally, do not connect more than one signal at a time to
the input jacks.
ꢁ. HIGH FREQUENCY FILTER
• The XLR connector and 1/4-inch TRS (tip-sleeve-ring)
connector accept a balanced signal while the RCA con-
nector accepts an unbalanced signal. A balanced signal
provides better noise rejection and is the preferred
method, especially if using a cable longer than 20 feet
(6 meters).
The HIGH FREQ switch tailors the overall high-
frequency response by 2 dB at 5 kHz and above. Leave
this switch in the “0 (NORMAL)” position unless:
• You want to subtly brighten or darken the sound of the
speakers.
• Perhaps you have hearing loss caused by too many
nights in front of a double Marshall stack.
• The 1/4-inch TRS jack can also accept an unbalanced
signal from a 1/4-inch TS (tip-sleeve) plug.
The connectors are wired as follows (per the AES/IEC
standard):
• You just like to mix on the bright side or dull side.
If your mixes consistently sound dull or dark when
you listen elsewhere, this usually indicates that your
monitors are too bright, relative to your normal hearing.
A bit less high-frequency energy usually fixes this, and
you can force the mix in this direction by reducing the
high-frequency output of the monitors by using the –2 dB
position of the switch.

Conversely, if your mixes are consistently too bright,
then adding some additional high-frequency energy in
the monitors satisfies your ears, and the resultant mix
has less HF content.
5. Power Switch
Use this switch to turn on or off the MR8. When the
power switch is turned on and the MR8 is plugged into
an AC outlet, the power LED on the front of the monitor
lights up to let you know the MR8 is ready to go.
It’s a real rush to mix really loud. But remember that
the resulting mix only sounds good when you play it at
least that loud. However strange it may sound, mixes
made at lower levels sound even better when played
loud, perhaps even a bit bigger than life.
6. Mains Input and Fuse
Connect the power cord to this IEC socket securely,
and plug the other end into your AC outlet. Make sure
the AC outlet has the correct voltage indicated next to
the IEC socket.
Get that sound level meter out. Decide what level
you’re going to mix at and use the meter to help keep
you mixing at that level. Your ears will thank you, and
your mixes will be better for it.
The fuse is located behind the fuse cover, at the bot-
tom of the IEC socket. See the “Troubleshooting” section
on page 9 for information about replacing the fuse.
4. LOW FREQ FILTER
The LOW FREQ switch tailors the overall low-frequency
response by +2 dB or +4 dB at 100 Hz.
7. Bass Reflex Port
• For most applications, use the “0 (NORMAL)” setting.
This takes the equalization circuit out of the signal path.
• If you want or need just a little extra low-frequency
output, use the +2 dB setting.
• If you want or need more low-frequency output, use the
+4 dB setting. Remember how things work in reverse,
so boosting the deep bass content on playback may
actually decrease it in the final mix.
A bass reflex system uses the radiation from the rear
of the woofer cone to extend the low-frequency response
of the speaker. The size of the port is carefully designed
with respect to the volume of the cabinet and the
characteristics of the woofer to produce low-frequency
extension.

The power indicator lights up when the
power switch [5] on the back of the MR8 is

Owner’s Manual
PROTECTION CIRCUITS
There are several protection mechanisms designed
into the MR8 to safeguard the loudspeakers and ampli-
fiers from inadvertent damage.
Input Signal Wiring
You should use high-quality, shielded cable to connect
the signal source to the SIGNAL INPUT jack [1] on the
MR8.
CAUTION: The protection circuits
are designed to prevent damage to
the loudspeakers under reasonable
and sensible conditions. Should you
choose to ignore the warning signs
• For balanced signals, foil shielded cables, such as
Belden 8451, 8761, or 9501 are commonly used for
studio wiring.
(i.e., excessive distortion), you can still damage the
speakers in the MR8 by overdriving them. Such damage
is beyond the scope of the warranty.
• Microphone cables work well for the XLR input.
• The better the shield, the better the immunity from
externally induced noise (like EMI and RFI). Route the
cable away from AC power cords and outlets. These are
common sources for hum in an audio signal. Wall warts
and line lumps are especially insidious hum inducers!
Overexcursion Protection
A 12 dB/octave high-pass filter at 60 Hz just prior to
the low-frequency amplifier prevents very low frequen-
cies from being amplified. Excessive low-frequency
energy below 60 Hz can damage the woofer by causing it
to “bottom out,” also known as overexcursion, which is
equivalent to a mechanical form of clipping.
You can purchase quality cables from your Mackie
dealer.
In certain home theater applications, it may be necessary
to connect the speaker outputs from a stereo receiver
to the inputs of the MR8, if the receiver doesn’t have
preamp outputs or other line-level output connections.
•
CAUTION: Do not attempt to connect
a speaker output directly to the input
of the MR8! Speaker levels are much
higher than line levels and can damage
the input circuitry in the MR8.
Thermal Protection
All amplifiers produce heat. The MR8 is designed to
be efficient both electrically and thermally.
• If for some reason the heatsink gets too hot, a thermal
You can, however, insert a speaker-level to line-level
switch activates and turns off the amplifier. This protec- signal attenuator between the receiver’s speaker output
tion operates independently for the low-frequency and
high-frequency amplifiers. Therefore, it is possible for
only the low-frequency or high-frequency amplifier to
shut down while the other remains on.
and the MR8’s input. Your Mackie dealer may be able to
help you find one, or you can build your own.
• When the heatsink cools down to a safe temperature,
the thermal switch resets and normal operation re-
sumes.
• If the heatsink temperature again gets too hot, the
shutdown process repeats. Should this happen, make
sure that airflow to the rear of ¡the cabinet is not
restricted. If the ambient air temperature is very warm,
try pointing a small fan toward the heatsink to increase
the airflow through the ventilation holes.
CARE AND CLEANING
Your Mackie Reference Studio Monitors will provide
many years of reliable service if you follow these guide-
lines.
• Avoid exposing the monitors to moisture.
• Avoid exposure to extreme cold (below freezing tem-
peratures).
• Use a dry cloth to clean the cabinets. Only do this when
the power is turned off.
Integrated Magnetic Shielding
The MR8 contains drivers with large magnetic
structures. The drivers’ magnets are shielded to help
prevent the magnetic field from radiating out into the
environment and playing havoc with computer monitors
or TV screens. Unshielded speakers can cause distortion
in both the shape and color of the picture if placed too
close to a CRT (cathode ray tube). If you have a particu-
larly sensitive computer monitor or TV screen, it may be
necessary to move the speakers a few inches away.

Appendix A: SERVICE INFO
If you think your Mackie product has a problem,
please check out the following troubleshooting tips and
No Sound
• Is the power indicator [8] on the front panel illumi-
nated? If not, refer to “No Power” above.
• Is the INPUT LEVEL [2] control turned up?
• Is the signal source turned up? Make sure the signal level
from the mixing console (or whatever device immedi-
ately precedes the studio monitor) is high enough to
produce sound.
do your best to confirm the problem. Visit the Support
where you will find lots of useful information such as
FAQs, and documentation. You may find the answer to
the problem without having to send your Mackie prod-
uct away.
• If it’s a stereo pair, try switching them around. For
example, if a left output is presumed dead, switch the
left and right cords at the monitor end. If the problem
switches sides, it’s not the monitor. It could be a bad
cable, or no signal from the mixer.
Troubleshooting
No Power
• Our favorite question: Is it plugged in?
• Make sure the power cord is securely seated in the IEC
socket [6] and plugged all the way into the AC outlet.
• Make sure the AC outlet is live (check with a tester or
lamp).
• Is the power [5] switch on the rear panel in the ON
position?
• Is the power indicator [8] on the front panel illumi-
nated? If not, make sure the AC outlet is live. If so, refer
to “No Sound” below.
Bad Sound
•
Is the input connector plugged completely into the jack?
If using a 1⁄4" plug, make sure it is plugged all the way in.
• Is it loud and distorted? Reduce the signal level at the
mixer.
• If possible, listen to the signal source with headphones
plugged into the preamp stage. If it sounds bad there,
it’s not the monitor.
• Too much bass or not enough bass? Move around the
room and see if the bass response changes. It’s possible
your listening position coincides with a room mode
where the low frequencies either become exaggerated
or nulled. If so, try moving the monitors to a different
position, or moving your listening position.
• If the power indicator is not illuminated, and you are
certain that the AC outlet is live, it is possible the fuse
has blown.
To remove and replace the fuse:
1. Disconnect the power cord from the IEC socket.
2. Remove the fuse drawer by prying it open with a
Noise/Hum/Buzz
small screwdriver. It will slide all the way out.
•
Check the signal cable between the mixer and the
monitor. Make sure all connections are secure. These
problems usually produce crackling noises, hum, or buzz.
•
If connecting an unbalanced output to the MR8 balanced
input, make sure the shield is connected to the unbalanced
ground of the source and to pins 1 and 3 of the XLR.
• If a CATV cable is connected to the system, try discon-
necting it. If the hum goes away, call your cable carrier
to check for proper grounding of the cable.
FUSE
• Make sure the signal cable is not routed near AC cables,
power transformers, or other EMI sources (including
wall warts and line lumps!). These sources usually
produce hum.
3. Remove the fuse and replace it with an equivalent-
type fuse.
• Is there a light dimmer or other triac-based device on
the same AC circuit as the monitor? Dimmers cause
buzzing noises. Use an AC line filter or plug the monitor
into a different AC circuit.
• Excessive hiss is an indication of an incorrect gain set-
ting somewhere before the speaker.
115 VAC unit: 3.15 amp slo-blo (T 3.15 AL/250V)
230 VAC unit: 1.6 amp slo-blo (T 1.6 AL/250V)
4. Replace the fuse drawer by pushing it all the way
back into the IEC socket.
If two fuses blow in a row, then something is very wrong.
See the “Repair” section on the next page to find out
how to proceed.
• If possible, listen to the signal source with headphones
plugged in. If it sounds noisy there, it’s not the monitor.
