INTRODUCTION  
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 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 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).  
The Transducers...  
The MR5s feature a 5.25-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 MR5 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 MR5 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 MR5.  
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 am-  
plifiers are Class A/B with power MOSFET outputs and  
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 60 Hz to 20 kHz.

AN EXTREMELY IMPORTANT NOTE  
ON MR5 BASS RESPONSE AND  
YOUR CONTROL ROOM.  
QUICK START  
We realize that you can’t wait to hook  
up your new Mackie MR5 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 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.  
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 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 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 MR5. The power  
LED [8] on the front panel will illuminate.  
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.  
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.  
High-Frequency Response  
The MR5s 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 MR5. 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 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.

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 MR5 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 MR5 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 MR5. When the  
power switch is turned on and the MR5 is plugged into  
an AC outlet, the power LED on the front of the monitor  
lights up to let you know the MR5 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.

PROTECTION CIRCUITS  
There are several protection mechanisms designed  
into the MR5 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  
MR5.  
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 MR5 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 MR5, 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 MR5! Speaker levels are much  
higher than line levels and can damage  
the input circuitry in the MR5.  
Thermal Protection  
All amplifiers produce heat. The MR5 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 HR624 MK2’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 shut-  
down 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 slightly damp cloth with a mild soap solution  
to clean the cabinets. Only do this when the power is  
turned off. Avoid getting moisture into any of the ope-  
ings of the cabinet, particularly where the drivers are  
located.  
Integrated Magnetic Shielding  
The MR5 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  
section of our website (www.mackie.com/support)  
where you will find lots of useful information such as  
FAQs, documentation, and user forums. 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  
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 14" 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 MR5 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.  
• 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.  
FUSE  
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: 1.6 amp slo-blo (T 1.6 A H/250V)  
230 VAC unit: 800 milliamp slo-blo (T 800 mA H/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.

MR5 Limited Warranty  
Please keep your sales receipt in a safe place.  
IMPORTANT: Make sure that the Service Request Number  
is plainly written on the shipping carton. No receipt, no  
warranty service.  
A. LOUD Technologies Inc. warrants all materials,  
workmanship and proper operation of this product for a period  
of one year from the original date of purchase. You may  
purchase an additional 24-month Extended Warranty (for a  
total of 36 months of coverage). Visit our website and follow  
the “Product Registration” links for details (www.mackie.com).  
If any defects are found in the materials or workmanship or  
if the product fails to function properly during the applicable  
warranty period, LOUD Technologies, at its option, will repair  
or replace the product. This warranty applies only to equipment  
sold and delivered within the U.S. and Canada by LOUD  
Technologies Inc. or its authorized dealers.  
E. LOUD Technologies reserves the right to inspect any  
products that may be the subject of any warranty claims before  
repair or replacement is carried out. LOUD Technologies may,  
at our option, require proof of the original date of purchase in  
the form of a dated copy of the original dealer’s invoice or sales  
receipt. Final determination of warranty coverage lies solely  
with LOUD Technologies.  
F. Any products returned to one of the LOUD Technologies  
factory-authorized service centers, and deemed eligible  
for repair or replacement under the terms of this warranty  
will be repaired or replaced. LOUD Technologies and its  
authorized service centers may use refurbished parts for repair  
or replacement of any product. Products returned to LOUD  
Technologies that do not meet the terms of this Warranty  
will not be repaired unless payment is received for labor,  
materials, return freight, and insurance. Products repaired  
under warranty will be returned freight prepaid by LOUD  
Technologies to any location within the boundaries of the USA  
or Canada.  
B. For faster processing (not to mention a free gift), register  
online or mail in the product registration card.  
C. Unauthorized service, repairs, or modification of Mackie  
products will void this warranty. To obtain repairs or  
replacement under warranty, you must have a copy of your  
sales receipt from the authorized Mackie dealer where you  
purchased the product. It is necessary to establish purchase  
date and determine whether your Mackie product is within  
the warranty period.  
D. To obtain warranty repair or replacement:  
G. LOUD Technologies warrants all repairs performed  
for 90 days or for the remainder of the warranty period.  
This warranty does not extend to damage resulting from  
improper installation, misuse, neglect or abuse, or to exterior  
appearance. This warranty is recognized only if the inspection  
seals and serial number on the unit have not been defaced or  
removed.  
1. Call Mackie Technical Support at 800/898-3211, 7  
AM to 5 PM Monday through Friday (Pacific Time) to get  
authorization for repair or replacement. Alternately, go to  
the Mackie website, click “Support” (www.mackie.com/  
support), and follow the instructions for reporting a warranty  
issue and submitting a request for an advance replacement.  
2. Advance Replacement: Mackie will ship a replacement  
unit to you along with an invoice for the suggested  
retail price of the replacement unit. You must return the  
defective unit immediately to cancel the invoice. If you do  
not return the defective unit within 30 days, you must pay  
the full amount stated in the invoice to satisfy your debt.  
H. LOUD Technologies assumes no responsibility for the  
timeliness of repairs performed by an authorized service  
center.  
I. This warranty is extended to the original purchaser. This  
warranty may be transferred to anyone who may subsequently  
purchase this product within the applicable warranty period  
for a nominal fee. A copy of the original sales receipt is  
required to obtain warranty repairs or replacement.  
3. Repair: When you call Mackie Technical Support, explain  
the problem and obtain a Service Request Number. Have  
your Mackie product’s serial number ready. You must have  
a Service Request Number before you can obtain factory-  
authorized service.  
J. This is your sole warranty. LOUD Technologies does not  
authorize any third party, including any dealer or sales  
representative, to assume any liability on behalf of LOUD  
Technologies or to make any warranty for LOUD Technologies  
Inc.  
Pack the product in its original shipping carton. Also  
include a note explaining exactly how to duplicate the  
problem, a copy of the sales receipt with price and date  
showing, your daytime phone number and return street  
address (no P.O. boxes or route numbers, please!), and the  
Service Request Number. If we cannot duplicate the problem  
or establish the starting date of your Limited Warranty, we  
may, at our option, charge for service time and parts.  
K. THE WARRANTY GIVEN ON THIS PAGE IS THE SOLE  
WARRANTY GIVEN BY LOUD TECHNOLOGIES INC.  
AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS  
AND IMPLIED, INCLUDING THE WARRANTIES OF  
MERCHANTABILITY AND FITNESS FOR A PARTICULAR  
PURPOSE. THE WARRANTY GIVEN ON THIS PAGE SHALL BE  
STRICTLY LIMITED IN DURATION TO ONE YEAR FROM THE  
DATE OF ORIGINAL PURCHASE FROM AN AUTHORIZED  
MACKIE DEALER. UPON EXPIRATION OF THE APPLICABLE  
WARRANTY PERIOD, LOUD TECHNOLOGIES INC. SHALL  
HAVE NO FURTHER WARRANTY OBLIGATION OF ANY  
KIND. LOUD TECHNOLOGIES INC. SHALL NOT BE LIABLE  
FOR ANY INCIDENTAL, SPECIAL, OR CONSEQUENTIAL  
DAMAGES THAT MAY RESULT FROM ANY DEFECT IN THE  
MACKIE PRODUCT OR ANY WARRANTY CLAIM. Some states  
do not allow exclusion or limitation of incidental, special, or  
consequential damages or a limitation on how long warranties  
last, so some of the above limitations and exclusions may not  
apply to you. This warranty provides specific legal rights and  
you may have other rights which vary from state to state.  
Ship the product in its original shipping carton, freight  
prepaid to the authorized service center. Write the Service  
Request Number in BIG PRINT on top of the box. The  
address of your closest authorized service center will be  
given to you by Technical Support, or it may be obtained  
from our website. Once it’s repaired, the authorized service  
center will ship it back by ground shipping, pre-paid (if it  
qualified as a warranty repair).  
Note: Under the terms of the warranty, you must ship or drop-  
off the unit to an authorized service center. The return ground  
shipment is covered for those units deemed by us to be under  
warranty.  
Note: You must have a sales receipt from an authorized  
Mackie dealer for your unit to be considered for warranty  
repair.
