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 Ampliers...

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.

MR5

This is where you connect your signal to the monitor,
and make adjustments to the frequency response of
the speakers to match the monitor’s location and your
room’s environment.

1. SIGNAL INPUTS

There are three types of input connectors: XLR (bal­anced), 1/4-inch (balanced), and RCA (unbalanced).
Since all three of them are connected together electri­cally, do not connect more than one signal at a time to
the input jacks.

• The XLR connector and 1/4-inch TRS (tip-sleeve-ring)

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).

• 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):

XLR TRS RCA

Hot (+) Pin 2 Tip Tip
Cold (–) Pin 3 Ring —

monitors are too bright, relative to your normal hearing.

you can force the mix in this direction by reducing the

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.

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.

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.

4. LOW FREQ FILTER

Owner’s Manual

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.

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.

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 LOW FREQ 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 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.

7. Bass Reex 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

MR5

There are several protection mechanisms designed
into the MR5 to safeguard the loudspeakers and ampli­fiers from inadvertent damage.

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 MR5 by overdriving them. Such damage
is beyond the scope of the warranty.

Overexcursion Protection

A 12 dB/octave high-pass filter at 60 Hz just prior to
the low-frequency amplifier prevents very low frequen­cies 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.

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

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.

• 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 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.

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 particu­larly sensitive computer monitor or TV screen, it may be
necessary to move the speakers a few inches away.

Input Signal Wiring

You should use high-quality, shielded cable to connect
the signal source to the SIGNAL INPUT jack [1] on the
MR5.

• 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!

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.

You can, however, insert a speaker-level to line-level
signal attenuator between the receiver’s speaker output
and the HR624 MK2’s input. Your Mackie dealer may be
able to help you find one, or you can build your own.

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 ope­ings of the cabinet, particularly where the drivers are
located.

Owner’s Manual

If you think your Mackie product has a problem,
please check out the following troubleshooting tips and
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.

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.

• 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

small screwdriver. It will slide all the way out.

3. Remove the fuse and replace it with an equivalent-

type fuse.

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.

-

No Sound

• Is the power indicator [8] on the front panel illumi­nated? 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 immedi­ately precedes the studio monitor) is high enough to
produce sound.

• 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.

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.

Noise/Hum/Buzz

•

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 discon­necting 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.

• 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.

• If possible, listen to the signal source with headphones
plugged in. If it sounds noisy there, it’s not the monitor.

XLR Connectors

XLR connectors are used to make balanced connec­tions to the MR5. They are wired as follows, according
to standards specified by the AES (Audio Engineering
Society).

XLR Balanced Wiring
Pin 1 = Shield
Pin 2 = Hot (+)
Pin 3 = Cold (–)

1/4" TRS Phone Plugs and
Jacks

1/4" TS Phone Plugs and Jacks

“TS” stands for Tip-Sleeve, the two connections avail­able on a mono 1/4" phone jack or plug. They are used
for unbalanced signals. It is okay to connect an unbal­anced 1/4" phone plug into the 1/4" TRS phone jack on
the MR5.

1/4" TS Unbalanced Wiring:
Sleeve = Shield
Tip = Hot (+)

RCA Plugs and Jacks

RCA-type plugs (also known as phono plugs) and
jacks are often used in home stereo and video equip­ment and in many other applications. They are unbal­anced and electrically equivalent to a 1/4" TS phone
plug.

“TRS” stands for Tip-Ring-Sleeve, the three connec­tions available on a stereo 1/4" or balanced phone jack
or plug. TRS jacks and plugs are used to make balanced
connections to the MR5.

1/4" TRS Balanced wiring:
Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)
