The amplifier is designed to provide maximum
acoustic output from the speaker, yet minimize
the danger of speaker damage due to overdriving.
The connecting wire between the amplifier
output and the low-frequency driver is kept to an
absolute minimum, so the damping factor of the
amplifier isn’t compromised by the resistance of
long speaker cables.
INTRODUCTION
Thank you for choosing Mackie Designs’
HRS120 Powered Subwoofer. We realize that
monitors are a critically important tool whether
your application is studio recording, audio/video
post production, hi-fi, or home theater, and the use
of a subwoofer not only improves low-frequency
accuracy for stereo monitoring and playback, but is
absolutely necessary for surround sound applications.
The HRS120 complements our line of studio
reference monitors and, like our HR824 and HR624,
meets all THX™ requirements for mixing and
monitoring multi-channel programs.
In order to achieve a seamless integration between
the subwoofer and the main speakers in the system,
speaker placement is very important. The charac-
teristics of the room and the location of the speakers,
including the subwoofer, relative to the walls and
your listening position can have a drastic effect on
the accuracy of the sound. We’ve provided a section
on positioning the subwoofers, offering tips on how to
find the best placement for your particular application.
In short, all the complex interconnected compo-
nents in the system are designed to work in harmony
with each other to produce the best possible sound.
The Transducers...
The subwoofer features a bottom-firing 12-inch
die-cast frame woofer and a 12-inch passive radiator
in the front.
The unique passive radiator design provides a
smooth response down to 19Hz — an astounding
accomplishment for a cabinet of this size! And since
the radiator is complementing and adding to the out-
put at the lowest frequencies, there is very little
distortion generated from the woofer because its cone
movement stays well within its maximum excursion.
The Cabinet...
What is it? The Advantages...
The cabinet is made of black oak veneered MDF
wood. Extensive internal bracing further increases
the strength and rigidity (stiffness) of the box.
The box is packed with an adiabatic polyester-fill
material to absorb internal reflections and dampen
standing waves.
The HRS120 is a high-resolution powered
subwoofer employing an internal variable 4th-order
Linkwitz-Riley crossover system with a built-in
front-firing mass-loaded passive radiator. Whew!
There are many benefits to integrating an active
crossover, power amplifier, and drivers into a single
cabinet, and we’ve taken full advantage of these
benefits in the design of the HRS120.
FR Series Power Amplifiers...
What better way to power the subwoofer than
with our acclaimed FR Series “Fast Recovery” power
amplifiers. Our Fast Recovery design uses low nega-
tive feedback, yet allows the amplifier to maintain low
distortion and stability even when driven into clipping.
The low-frequency amplifier produces up to 400
watts continuous (500 watts peak) before clipping.
•
The crossover point is variable so that the high-
pass output can be programmed to match the
frequencies the main speakers are best able to
reproduce.

PLACEMENT
AN IMPORTANT NOTE
Corner or Center Placement
ON HRS120 BASS
Placing the subwoofer in a corner (corner
loading) excites the most room modes in the
room, which tends to smooth the individual
peaks and dips caused by each standing wave.
Moving the subwoofer outward from the corner
along the wall results in fewer standing waves,
but may result in noticeable peaks at certain
frequencies.
Some people prefer to place the subwoofer
between the left and right main speakers, so
that all the sound is coming from the same
plane. Some prefer to use two subwoofers and
place one with the left speaker and the other
with the right speaker. The Master Out/Slave
In connections on the HRS120 allow you to do
this quite easily.
Another benefit of corner placement is in-
creased efficiency and lower distortion. The
energy that is reflected off the walls reinforces
the direct sound, putting less of a demand on
the power amplifier to reach higher sound
pressure levels.
It is important that the corner has good
structural strength, or the low-frequency en-
ergy can cause rattling and other distracting
vibrations.
RESPONSE AND YOUR
CONTROL ROOM OR
LISTENING ROOM
You’ve heard it before. “Low-frequencies are
non-directional, so it doesn’t matter where you
place the subwoofer.” Although it is true that fre-
quencies below about 100Hz are non-directional,
it is also true that a lot of factors can conspire to
thwart the HRS120’s 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. Here are some tips to help
you find the best placement for your HRS120
and optimize the low-frequency response in
your particular room. Consider the following:
Room acoustics and bass-handling ability
Nobody likes to buy a subwoofer and a new
set of speakers and then be told that they
should spend extra bucks on bass traps or a re-
modeling job. But the simple fact is, “standard”
rooms, i.e. rectangular rooms in conventional
business or residential structures, are rarely if
ever conducive to optimal low bass reproduc-
tion without some modifications.
Experiment with the orientation of the
subwoofer. The driver in the HRS120 faces
downward toward the floor while the passive
radiator faces out the front. In some cases, the
subwoofer may sound better with the passive
radiator facing toward the wall. It may be help-
ful to play steady-state tones or pink noise
while a partner moves the subwoofer (perhaps
on a small wheeled cart), to make it easier to
hear the differences in the sound as the changes
in placement and orientation are made.
However, understanding what can cause
degradation of the low-frequency response in
a room can help in choosing a location that can
minimize the problems associated with poor
bass response—most notably interference
and resonance.
Interference is caused when the reflected
wave from the surrounding walls arrive out-of-
phase with the direct sound. This can weaken
or even cancel the sound. Keeping the distance
between the subwoofer driver and any adjacent
walls no longer than 1/8 of a wavelength (20 in.
or 51 cm at 80Hz) can minimize interference.
Room resonance is caused by the reinforce-
ment of certain frequencies between 20Hz and
200Hz, which creates “standing waves” or room
modes. These resonant frequencies are deter-
mined by the dimensions of the room. The bass
response is sharply boosted for a narrow band
near resonance, and then appears to be attenu-
ated between resonances.
Principle of Reciprocity
One trick that has been used successfully to
find the best location for a subwoofer is placing
the subwoofer in your listening position. The
principle of reciprocity says that you can find
the best location for the subwoofer by switching
places between the listening position and the
subwoofer position. It is important that the cabi-
net be raised off the ground and at the same level
as your ears. If that’s not possible, at least put the
subwoofer in the same location as your listening
position to achieve a close approximation.

crawl on the floor on your hands and knees until
you find a spot where the bass sounds the best,
with a smooth, tight response. Your ears need
to be at the same height that the subwoofer’s
driver will be when it is sitting on the floor. If
you have access to a real-time analyzer (RTA),
play pink noise over the system and use the
RTA to find a location that exhibits the flatest
bass response. Once you’ve found the place
where the bass sounds the best, put the

A Few Words About THX™ pm3™
Certification
Nearly two decades ago, George Lucas
turned a passion for great sound into the
world’s most accepted and trusted solution for
achieving it. The standard was named THX
(for Tomlinson Holman, who developed the
THX Sound System when he was the research
and technical director at Lucasfilm Ltd.™ in
the early 80s), and today, with hundreds of
thousands of home theater customers and
more than 3000 THX Certified movie theaters
enjoying its benefits, the THX name has be-
come nothing short of legendary. Simply put:
when it comes to premium sound, no other
name so closely defines ‘quality’ for millions of
movie-goers and home theater enthusiasts alike.
Today, a new landscape is emerging. A land-
scape comprised of hundreds of small,
professional multi-channel facilities, whose
need for differentiation, expert technical and
marketing support, and a true, multi-channel
standard is becoming a competitive fact of life.
Again, THX has a singular solution and this
time it’s called THX pm3 Certification.
All facilities involved with mixing and/or
monitoring of multi-channel material should
have the option to use pm3. THX pm3 Certifi-
cation is ideal for DVD mastering, sweetening,
and mixing; and is also perfect for facilities
doing work in broadcast, music, or multi-media
applications.
subwoofer there and it should sound just as
good from your listening position.
Polarity
The setting of the polarity switch can affect
how the low frequencies sound in relation to the
main speakers. Listen to bass-heavy music with
the polarity switch in and out. In one position
the low frequencies should sound full, while in
the other position they may sound hollow and
thin. Choose the position that yields the fullest
low-frequency sound.
Feel free to experiment
In many respects, every room is unique in
terms of its acoustics. Even after you’ve placed
your subwoofer where you think it’ll sound
best, try moving it around. You might be pleas-
antly surprised.
Additional Tidbits of Wisdom
• Avoid using EQ to compensate for dips in
the frequency response caused by room
modes. It is better to place the subwoofer in
a position where dips are minimized and
use the EQ to smooth out any peaks.
• Provide at least six inches clearance
around the heatsink to allow air to get at it.
• Provide at least three feet clearance from a
TV, computer monitor, or any form of
HRS120 THX pm3 Certification
magnetic media (video and audio recording
tapes, computer disks, etc.), to prevent the
HR120’s powerful magnet from distorting the
video screen or erasing the magnetic media.
Anyone seeking THX Certification for their
studio, or striving to maintain THX standards,
can use the HRS120s and rest assured that
their facility is in full compliance.
• When you shut down your equipment, turn
off the HRS120 powered subwoofer first
(and any other powered speakers in the
system) to prevent thumps and other
noises generated by any upstream equip-
ment from coming out the speakers. When
powering up, turn on the powered speakers
and subwoofer last.

PROTECTION CIRCUITS CONNECTIONS
There are several protection mechanisms
designed into the HRS120 to safeguard the
loudspeaker and amplifier from inadvertent
damage.
Input and Output Signal Wiring
You should use high-quality, shielded cable
to connect the signal source to the LEFT and
RIGHT IN
and OUT
jacks on the HRS120.
• Foil shielded cables, such as Belden 8451,
8761, or 9501 are commonly used for studio
wiring.
Peak Limiter
A peak limiter is located at the input to the
power amplifier section. It monitors both the
amplifier output signal and the power supply
voltages to guard against clipping and over-
loading the amplifier. This allows for loud and
punchy bass performance without distortion,
ensuring long-term reliability.
• Microphone cables work well.
• 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!
Thermal Protect
You can purchase quality cables from your
Mackie dealer.
All amplifiers produce heat. The HRS120 is
designed to be efficient both electrically and
thermally.
• If for some reason the heatsink or power
transformer gets too hot, a thermal switch
activates, placing the HRS120 into Standby
mode.
• Should this happen, make sure that airflow
to the rear of the cabinet is not restricted.
• When the heatsink or power transformer
cools down to a safe temperature, the switch
resets and normal operation resumes.
• In certain home theater applications, it
may be necessary to connect the speaker
outputs from a stereo receiver to the inputs
of the HRS120s, 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
HRS120! Speaker levels are
much higher than line
Note: The POWER LED remains lit if the ther-
mal protection circuit is activated.
levels and can damage the input circuitry
in the HRS120.
You can, however, insert a speaker-level to
line-level signal attenuator between the
receiver’s speaker output and the HRS120’s
input. Your Mackie dealer may be able to
help you find one, or you can build your
own. Contact our tech support department
for more information.

SERVICE INFO
Bad Sound
Details concerning Warranty Service are
spelled out on the Warranty Card included with
your subwoofer (if it’s missing, let us know and
we’ll rush one to you).
If you think your subwoofer has a problem,
please do everything you can to confirm it before
calling for service, including reading through
the following Troubleshooting section. Doing
so might save you from deprivation of your
monitor and the associated suffering.
Of all Mackie products returned for service
(which is hardly any at all), roughly 50% are
coded “CND” — Could Not Duplicate, which
usually means the problem lay somewhere else
in the system. These may sound obvious to you,
but here are some things you can check:
• Is the input connector plugged completely
into the jack?
• 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 subwoofer.
• 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 subwoofer to a different
position, or moving your listening position.
• If the signal source is an LFE or subwoofer
output from a home theater preamplier,
make sure the signal level for the low-
frequency output is turned up in the
preamp. If you have connected the low-
frequency signal to the LEFT (and RIGHT)
INput, make sure the FILTER BYPASSED
switch is pushed in.
Troubleshooting
No Power
• Our favorite question: Is it plugged in?
• Make sure the power cord is securely
seated in the IEC socket
all the way into the AC outlet.
and plugged
• Make sure the AC outlet is live (check with
a tester or lamp).
Noise/Hum/Buzz
• Check the signal cable between the mixer/
preamp and the subwoofer. Make sure all
connections are secure. These problems
usually produce crackling noises, hum, or buzz.
• If connecting an unbalanced output to the
HRS120 balanced input, make sure the
shield is connected to both pins 1 and 3 on
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
(SCR) device on the same AC circuit as the
monitor? Dimmers cause buzzing noises.
Use an AC line filter or plug the subwoofer
into a different AC circuit.
• If possible, listen to the signal source with
headphones plugged in. If it sounds noisy
there, it’s not the subwoofer.
• Is the POWER
switch on the rear panel
in the ON position?
• Is the POWER
LED or BYPASSED
LED on the rear panel illuminated? If not,
make sure the AC outlet is live. If so, refer
to “No Sound” below.
• If the POWER LED or BYPASSED
LED
is not illuminated, and you are certain that
the AC outlet is live, it will be necessary to
have the HRS120 serviced. There are no
user-serviceable parts inside. Refer to
“Repair” at the end of this section to find
out how to proceed.
No Sound
• Is the POWER
LED or BYPASSED
LED on the rear panel illuminated? If not,
refer to “No Power” above.
• Is the INPUT SENSITIVITY control
turned up?
• Is the signal source turned up? Make sure
the signal level from the mixing console (or
whatever device immediately precedes the
subwoofer) is high enough to produce sound.

The text is a compilation based on input
from a number of sources including Cam Jones,
Terry Wetherbee, Marcelo Vercelli, and Keith
Olsen. Dave Franzwa produced this manual
using the following tools:
Initially written in Microsoft® Word 98 for
the Macintosh, the text was imported into
Adobe PageMaker® 6.5. Illustrations were pro-
duced in Adobe Illustrator® 9.0. Most of the
work was done on a Power Macintosh® G4 with
Mac OS 9.1 installed. This machine has a
PowerPC G4 processor, 384MB of RAM, a 10GB
internal hard drive, an internal Matshita DVD-
ROM drive, and an internal Iomega Zip™
Drive for backup and transfer of files. A
Hewlett-Packard LaserJet 5000N with a duplex
tray installed (to save trees) was used to print
out laser proofs. PDF files were created with
Acrobat™ Distiller 4.0. A wind-driven open
window provided much-needed relief as the
production deadline approached. This entire
manual was written and produced while sitting
in a comfy chair, which was actually more
comfy than the one used while producing the
HR824 manual.
