Introduction
The MR8mk2 Mackie Reference Monitor is the perfect
solution for those ready to step up to a truly professional,
high-output monitoring system. The completely
re-voiced MR8mk2 features all-new high-end drivers,
delivering unmatched low frequency extension and
clear, articulate highs. The MR8mk2’s precision Class
A/B amplification (100W LF / 50W HF) offers
class-leading power, tons of connection options and
simple acoustic controls for room correction. Featuring
an optimally sized custom waveguide and
•
•
•
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 40 Hz to 20 kHz.
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.
minimum-diffraction molded baffle, the MR8mk2
delivers superior stereo imaging and depth. With
unbelievable power, performance and clarity, the
MR8mk2 stands alone in its class.
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.
Investments in Excellence...
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 MR8mk2s 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).
All-New Transducers...
The MR8mk2s feature an 8-inch high-precision, low-
distortion woofer and a 1-inch neodymium silk dome
tweeter.
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 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 MR8mk2 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!
Precision Power Amplifiers...
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.
What are they? The Advantages...
The MR8mk2 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 MR8mk2.
Cabinet Design...
The cabinet is made of MDF with a textured matte-
black finish. Internal bracing increases the strength and
rigidity of the box. An open-cell adiabatic foam material
fills the inside of the box to absorb internal reflections
and dampen standing waves.
•
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.

An Extremely Important Note on
MR8mk2 Bass Response and Your
Control Room.
Quick Start
We realize that you can’t wait to hook up your new
Mackie MR8mk2 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.
Your new MR8mk2s achieve their best bass
response in a room that’s optimized for bass
reproduction. A lot of factors can conspire to
thwart the MR8mk2s’ 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.
Low-Frequency Response
3. Leave the High Freq [3] and Low Freq [4] Filter
switches at their Normal positions.
When you put your MR8mk2s 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.
4. Connect the line-level monitor signal from your mixer,
preamp, or other signal source to the INPUT [1] jack on
the MR8mk2 Studio Monitor (1⁄4-inch PHONE, XLR, or
RCA).
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.
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.
High-Frequency Response
6. Start your signal source (tape deck, CD, DAW, or
whatever), but leave the master volume control on your
mixer or preamp down.
The MR8mk2s 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.
7. Turn on the power switch [5] on the MR8mk2. The
power LED [8] on the front panel will illuminate.
8. Slowly turn up the INPUT LEVEL [2] control on the
back of the monitor to its fully clockwise position
(MAX).
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.
9. Adjust the master volume on your mixer or preamp to
a comfortably loud listening level. If the MR8mk2 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.
•
When you shut down your equipment, turn off the
MR8mk2 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.
Enjoy the silky smooth highs and authoritative,
commanding lows of the MR8mk2. Then read the rest of
this manual.
• Save the shipping box! You may need it someday.
• Save your sales receipt in a safe place. It’s your
warranty!

Rear Panel Description
This is where the signal is connected to the monitor
and adjustments are made to the frequency response
of the speakers to match the monitor’s location and the
room’s environment.
2. INPUT LEVEL
The MR8mk2 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.
• The MR8mk2 is designed to operate with a +4 dBu
signal when the input level control is in the max
position. In other words, wide open.
1. SIGNAL INPUTS
There are three types of input connectors: XLR,
1/4-inch, and RCA. Since all three of them are
connected together electrically, do not connect more
than one signal at a time to the input jacks.
• Refer to the Quick Start section on page 5 for the
level-setting procedure.
• The XLR connector and 1/4-inch TRS (tip-ring-sleeve)
connector accept a balanced signal while the RCA
connector 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).
3. HIGH FREQUENCY FILTER
This 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

• You just like to mix on the bright side or dull side.
XLR
TRS
RCA
If the mixes consistently sound dull or dark when
you listen elsewhere, this usually indicates that the
monitors are too bright, relative to your normal hearing.
A bit less high-frequency energy usually fixes this, and
the mix may be forced in this direction by reducing the
high-frequency output of the monitors by using the –2 dB
position of the switch.

Conversely, if the 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
Switch up to turn the MR8mk2 on. Make sure the
level control is down before you turn it on. When the
power switch is turned on and the MR8mk2 is plugged
into an AC outlet, the power LED on the front of the
monitor lights up to let you know the MR8mk2 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.
Press the bottom of this switch to put the speaker
into standby mode. It will not function, but the
circuits are still live. To remove AC power, either turn
off the AC supply, or unplug the power cord from the
speaker and the AC supply.
Get that sound level meter out. Decide what level to
mix at and use the meter to help keep mixing at that
level. Your ears will thank you, and your mixes will be
better for it.
6. MAINS INPUT AND FUSE
4. LOW FREQUENCY FILTER
Connect the power cord to this IEC socket securely,
and plug the other end into a live AC outlet. Make sure
the AC outlet has the correct voltage indicated next to
the IEC socket.
This switch tailors the overall low-frequency response
by +2 dB or +4 dB at 100 Hz.
• For most applications, use the “0 (NORMAL)” setting.
This takes the equalization circuit out of the signal path.
• If a little extra low-frequency output is necessary, use
The fuse is located behind the fuse cover, at the
bottom of the IEC socket. See the “Troubleshooting”
section on page 9 for information about replacing the
fuse.
the +2 dB setting.
• If even more low-frequency output is necessary, 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.
7. BASS REFLEX PORT
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.

Protection Circuits
There are several protection mechanisms designed
into the MR8mk2 to safeguard the loudspeakers and
amplifiers 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
MR8mk2.
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 (i.e., excessive distortion), you can still damage
the speakers in the MR8mk2 by overdriving them. Such
damage is beyond the scope of the warranty.
• For balanced signals, foil shielded cables, such as
Belden 8451, 8761, or 9501 are commonly used for
studio wiring.
• 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 40 Hz just prior to
the low-frequency amplifier prevents very low
frequencies from being amplified. Excessive
low-frequency energy below 40 Hz can damage the
woofer by causing it to “bottom out,” also known as
overexcursion, which is equivalent to a mechanical form
of clipping.
Quality cables may be purchased from Mackie dealers.
•
In certain home theater applications, it may be necessary
to connect the speaker outputs from a stereo receiver to
the inputs of the MR8mk2, 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
MR8mk2! Speaker levels are much higher
Thermal Protection
than line levels and can damage the input circuitry in
the MR8mk2.
All amplifiers produce heat. The MR8mk2 is designed
to be efficient both electrically and thermally.
However, it is possible to insert a speaker-level to
line-level signal attenuator between the receiver’s
speaker output and the MR8mk2’s input. The local
Mackie dealer should be able to assist, or you can build
your own.
• If for some reason the heatsink gets too hot, a thermal
switch activates and turns off the amplifier. This
protection 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.
Care and Cleaning
• When the heatsink cools down to a safe temperature,
the thermal switch resets and normal operation
resumes.
• 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.
Mackie Reference Studio Monitors will provide many
years of reliable service if you follow these guidelines.
• Avoid exposing the monitors to moisture.
• Avoid exposure to extreme cold (below freezing
temperatures).
• Use a dry cloth to clean the cabinets. Only do this when
Integrated Magnetic Shielding
the power is turned off.
The MR8mk2 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 particularly sensitive computer monitor or TV
screen, it may be necessary to move the speakers a few
inches away.

section of our website (www.mackie.com/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
product 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

position?
• If possible, listen to the signal source with headphones
plugged into the preamp stage. If it sounds bad there,
it’s not the monitor.
• Is the power indicator [8] on the front panel
illuminated? If not, make sure the AC outlet is live.
If so, refer to “No Sound” below.
• 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 MR8mk2
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
disconnecting 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.
115 VAC unit: 1.6 amp slo-blo (T 1.6 AL/250V)
• 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.
