for a period of time. The U.S. Government’s Occupational Safety and Health
Administration (OSHA) has specified the permissible noise level exposures
shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits could result
in some hearing loss. To ensure against potentially dangerous exposure to high sound
pressure levels, it is recommended that all persons exposed to equipment capable
of producing high sound pressure 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:

How to Use This Manual:
Afer this introduction, a getting started guide will help
you get things set up fast. The hookup diagrams show some
DRM Professional Passive Loudspeaker Series
typical DRM-P loudspeaker setups, including some that
involve the DRM8S-P subwoofer.
The following steps will help you set up the loudspeakers
quickly.
. Make all initial connections with the power switches
OFF on all equipment. Make sure the master volume, level
and gain controls are all the way down.
2. Connect the outputs from the mixing console (or other
signal source) to the inputs on the rear panel of the power
amplifier.
3. If not using a subwoofer, connect the speaker output(s)
from the power amplifier to the input on the rear panel
of the loudspeaker(s).
4. If using a subwoofer, connect the speaker output(s)
from the power amplifier to the input on the rear panel
of the subwoofer(s), then connect the thru outputs
from the subwoofer to the inputs of the loudspeakers.
5. Turn the mixer (or other signal source) on.
6. Turn the power amplifier on. Turn up its volume
or gain control(s) as recommended by the manufacturer.
7. Start the signal source and raise the mixer’s main
L/R fader up to a comfortably loud listening level.
This icon marks information that is critically

Things to Remember:
• Never listen to loud music for prolonged periods. Please see
the Safety Instructions on page 2 for information on hearing
protection.
• As a general guide, the mixer (or other signal source)
should be turned on first, followed by the amplifier.
As such, the amplifier should also be turned o first,
followed by the mixer. This will reduce the possibility
of any turn-on or turn-o thumps and other noises
generated by any upstream equipment from coming
out of the speakers.
• Save the shipping boxes and packing materials! You may
need them someday. Besides, the cats will love playing
in them and jumping out at you unexpectedly. Remember
to pretend like you are surprised!
• Save your sales receipt in a safe place.

One convenient feature of the Mackie DRM passive speakers is the ability to connect multiple speakers together easily,
as shown in the illustration above.
DRM passive speakers may be daisy-chained via the speakON connector labeled “THRU”. Simply plug the signal source
(i.e., mixer output) into the amplifier’s input jack(s), patch the amplifier’s speakON output jack(s) to the DRM passive
speaker’s input jack, the thru jack to the next speaker’s input jack, and so on, daisy-chaining multiple DRM passive
speakers.

Rear Panel Features
The DRM Series passive loudspeakers have speakON
input and thru connectors, although each of the jacks
may be used as an input or a thru connection (because
the connectors are wired in parallel).
Use only one jack as an input connector.
speakON connectors are designed to handle
the higher currents produced by amplifiers and have
a locking feature to prevent accidental disconnections.
Simply line up the tabs on the plug with the jack
on the DRM Series passive loudspeaker, push it
in and rotate it clockwise /4 turn to lock it in place.

Placement
WARNING: Installation should only
be done by an experienced technician.
Improper installation may result in damage
to the equipment, injury or death. Make sure that
the loudspeaker is installed in a stable and secure
way in order to avoid any conditions that may be
dangerous for persons or structures.
DRM loudspeakers are designed to sit on the floor or
stage as the main PA or as monitors. They may also be
pole-mounted via the built-in socket on the bottom of
the cabinet. Be sure the pole is capable of supporting
the weight of the loudspeaker. The SPM400 is a great
option when using a subwoofer.
These loudspeakers may also be flown via their
integrated fly points as detailed on the following
pages. Be sure to read the PA-A2 Eyebolt Installation
Instructions, as well.
NEVER attempt to suspend a DRM
loudspeaker by its handles.
Check to make sure that the support surface
(e.g. floor, etc.) has the necessary mechanical
characteristics to support the weight of the
loudspeaker(s).
When pole-mounting loudspeakers, be sure that they
are stabilized and secured from falling over or being
accidentally pushed over. Failure to follow these
precautions may result in damage to the equipment,
personal injury, or death.
In addition to the two pole-mounts – see previous
page – the DRM22-P and DRM25-P may be laid out
horizontally as monitors for the band at a 50˚ angle
(as seen below).
Owner’s Manual
Room Acoustics
DRM loudspeakers are designed to sound fantastic
in nearly every application.
But, room acoustics play a crucial role in the overall
performance of a sound system. However, the wide
high-frequency dispersion of the DRM loudspeakers
helps to minimize the problems that typically arise.
Here are some additional placement tips to help
overcome some typical room problems that might arise:
• Placing loudspeakers in the corners of a room
increases the low frequency output and can cause
the sound to be muddy and indistinct.
• Placing loudspeakers against a wall increases
the low frequency output, though not as much
as corner placement. However, this is a good way
to reinforce the low frequencies, if so desired.
• Avoid placing the speakers directly on a hollow
stage floor. A hollow stage can resonate at certain
frequencies, causing peaks and dips in the frequency
response of the room. It is better to place them
on a sturdy stand designed to handle the weight
of the loudspeaker.
• Position the loudspeakers so the high-frequency
drivers are two to four feet above ear level for
the audience (making allowances for an audience
that may be standing/dancing in the aisles).
High frequencies are highly directional and tend
to be absorbed much easier than lower frequencies.
By providing direct line-of-sight from the loudspeakers
to the audience, you increase the overall brightness
and intelligibility of the sound system.
• Highly reverberant rooms, like many gymnasiums
and auditoriums, are a nightmare for sound system
intelligibility. Multiple reflections o the hard walls,
ceiling, and floor play havoc with the sound. Depending
on the situation, you may be able to take some steps
to minimize the reflections, such as putting carpeting
on the floors, closing draperies to cover large glass
windows, or hanging tapestries or other materials
on the walls to absorb some of the sound.
The Running Man logo is rotatable
for when the DRM22-P or DRM25-P
is used as a monitor; you can also rotate
it when the DRM35-P is flown horizontally!
However, in most cases, these remedies are not
possible or practical. So what do you do? Making
the sound system louder generally doesn’t work
because the reflections become louder, too.
The best approach is to provide as much direct sound
coverage to the audience as possible. The farther away
you are from the speaker, the more prominent will be
the reflected sound.
Use more speakers strategically placed so they
are closer to the back of the audience. If the distance
between the front and back speakers is more than
about 00 feet, you should use an external delay
processor to time-align the sound. (Since sound
travels about foot per millisecond, it takes about
/0 of a second to travel 00 feet.)

Rigging
WARNING: Installation should only be done
by an experienced technician. Improper
installation may result in damage to the
equipment, injury or death. Make sure that the
loudspeaker is installed in a stable and secure way
in order to avoid any conditions that may be dangerous
for persons or structures.
WARNING: The cabinet is suitable for rigging
via its fly points. NEVER attempt to suspend
a DRM loudspeaker by its handle.
The fly points are shown on the following page while
examples of a flown DRM35-P are displayed below.
The DRM35-P may be flown horizontally
or vertically, but the other DRM passive
loudspeakers may only be flown vertically.
Rigging Design Practices
Rigging a loudspeaker requires determining:
. The rigging methods and hardware that
meet static, shock, dynamic, and any other load
requirements for supporting the loudspeaker
from structure.
Rigging Hardware and Accessories
Rigging our loudspeakers will invariably require
hardware not supplied by us. Various types of
load-rated hardware are available from a variety
of third-party sources. There are a number of such
companies specializing in manufacturing hardware
for designing and installing rigging systems. Each
one of these tasks is a discipline in its own right.
Because of the hazardous nature of rigging work
and the potential liability, engage companies that
specialize in these disciplines to do the work required.
We do oer certain accessory rigging items and some
of them may be used with a variety of products. While
these accessories are intended to facilitate installation,
the wide variety of possible installation conditions and
array configurations do not permit us to determine their
suitability or load rating for any particular application.
We are not in the business of providing complete
rigging systems, either as designers, manufacturers,
or installers. It is the responsibility of the installer to
provide a properly engineered, load-certified rigging
system for supporting the loudspeaker from structure.
DRM loudspeakers may be individually
flown using a PA-A2 Eyebolt Kit, part
number 205054.
DRM Professional Passive Loudspeaker Series
2. The design factor and required WLL (Working
Load Limit) for this support.
We strongly recommend the following rigging
practices:
. Documentation: Thoroughly document the design
with detailed drawings and parts lists.
2. Analysis: Have a qualified professional, such
as a licensed Professional Engineer, review and
approve the design before its implementation.
3. Installation: Have a qualified professional rigger
do the installation and inspection.
4. Safety: Use adequate safety precautions
and back-up systems.
Rigging Notes
The DRM loudspeaker’s integral mounting
points are designed to support only the weight
of their own loudspeaker with suitable, external
hardware. This means that each DRM loudspeaker
must be supported independently of any other DRM
loudspeaker and any other loads. At least three rigging
points must be used to hang each DRM loudspeaker.

A note on eyebolts
Eyebolt working load limits are
significantly de-rated when angular lifs
are applied. If an application requires
an angular lif greater than 45˚, a swivel
hoist ring or similar fitting must be used.
These fittings have full swivel and pivot
action which helps avoid side loads.
WARNING: When the FB00 Flybar is used
to suspend a system, it cannot retain
a 0: design factor at certain pick points.
In some situations, suspended and installed arrays may
be configured with other design factors (e.g. 8: or 5:),
LOUD Audio, LLC. only recommends using the desired
0: design factor.

Protection
A protection circuit is built into the DRM passive
loudspeakers to protect their high-frequency drivers
from excessive power. When tripped, the protection
circuit substantially reduces the power to the HF driver.
Afer the driver cools to a safe operating temperature,
the protection circuit resets and normal operation
resumes. However, if the protection circuit senses
excessive power, it will trip again. In this case, it is
necessary to reduce the power to the loudspeaker
by either turning down the gain controls on the power
amplifier or turning down the master volume control
on the mixer or other sound source.
CAUTION: The protection circuit is designed
to protect the HF driver under reasonable
and sensible conditions. Should you choose
to ignore the warning signs (i.e., frequent clip LED
indications on the mixer or power amplifier, excessive
distortion), you can still damage the drivers in the DRM
passive loudspeakers by overdriving them past their
recommended amplifier power-handling ratings, or past
the point of amplifier clipping. Such damage is beyond
the scope of the warranty.
Owner’s Manual
Preventing Loudspeaker Damage
Speaking of clipping, this is likely the number one
cause of damage to loudspeakers. Clipping occurs
when the signal at the output of any device in the
system (not just the amplifier) reaches its maximum
level. The input signal to the device may continue to
increase, but the output simply stops, and is characterized by a “flat-top” appearance to the waveform.
Normal Sine Wave Signal
Clipped Sine Wave Signal
Amplifier Power
The DRM passive loudspeakers have three powerhandling numbers: continuous, program and peak.
So how much power do you really need to drive these
loudspeakers? The answer to that question depends on
what type of program material you are running through
the system and how loud it needs to be.
Some audio signals have lots of momentary peaks
whose amplitudes extend far above the average overall
level of the program. Percussion instruments are
a good example of this. Other types of signals, like
highly compressed rock music, have a higher average
signal level with fewer peaks. Speech reinforcement
requires less power overall, but involves large momentto-moment variations in level.
Assuming you want to use the full capability
of the loudspeaker, and the program contains at least
some momentary peaks, we recommend that you use
an amplifier that is rated at twice the continuous power
rating of the loudspeaker (into 8 Ω). For the DRM22-P
loudspeaker, this would be 800 watts × 2 = 600 watts
per channel into 8 Ω. This ensures that the amplifier
can reproduce peaks that are 6 dB higher than
the continuous (rms) power-handling rating
before clipping occurs.
Recommended Power Ratings
• DRM22-P: 600W into 8 Ω (800W rms × 2)
• DRM25-P: 2000W into 8 Ω (000W rms × 2)
• DRM35-P: 2300W into 8 Ω 50W rms × 2)
• DRM2A-P: 2000W into 8 Ω (000W rms × 2)
• DRM8S-P: 2000W into 8 Ω (000W rms × 2)
Clipping interrupts the motion of the transducer,
creating distortion and excessive heat in the driver,
which can damage it over time.
Some folks think that if they use a power
amplifier whose power rating is below the maximum
power-handling rating of the loudspeaker, then
they can’t possibly damage the loudspeaker.
But if the amplifier is driven into clipping, even
a lower power amplifier can damage the loudspeaker.
The bottom line is that to prevent damage
to the loudspeakers, you must have a properly
operating sound system. Proper operation of a sound
system includes being aware of types of audio signals
being reproduced, controlling the output levels
accordingly, and operating all the devices in the system
so that no clipping occurs within the signal chain.
Care and Maintenance
Your DRM loudspeakers will provide many years
of reliable service if you follow these guidelines:
• Avoid exposing the loudspeakers to moisture.
If they are set up outdoors, be sure they are under
cover if rain is expected.
• Avoid exposure to extreme cold (below freezing
temperatures). If you must operate the loudspeakers
in a cold environment, warm up the voice coils slowly
by sending a low-level signal through them for about
5 minutes prior to high-power operation.
• Use a dry cloth to clean the cabinets. Only
do this when the power is turned o. Avoid getting
moisture into any of the openings of the cabinet,
particularly where the drivers are located.

Appendix A: Service Information
If you think your DRM loudspeaker 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
and other documentation. You may find the answer
to the problem without having to part with your loudspeaker.
Troubleshooting
No sound
• Are the level controls on the mixer or amplifier turned
all the way down? Follow the procedures in “Getting
Started” section on page 4 to verify that all of the
volume controls in the system are properly adjusted.
• Is the signal source working? Make sure
the connecting cables are in good repair and securely
connected at both ends. Make sure the output level
control on the mixing console is turned up suciently
DRM Professional Passive Loudspeaker Series
to drive the inputs of the speaker.
• Make sure the mixer does not have a mute on
or a processor loop engaged. If you find something
like this, make sure the level is turned down before
disengaging the oending switch.
• Are all the connections good and sound?
Make sure all of the connecting cables are in good
repair and securely connected at both ends.
Poor bass performance
• Check the polarity of the connections between
the amplifier and the loudspeakers. You may have
your positive and negative connections reversed
at one end of one cable.
Bad sound
• Is it loud and distorted? Make sure that you’re not
overdriving a stage in the signal chain. Verify that
all level controls are set properly.
• Is the input connector plugged completely into
the jack? Be sure all connections are secure.
• If possible, listen to the signal source with
headphones plugged into the preamp stage.
If it sounds bad there, it’s not the loudspeaker.
• 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 loudspeakers to a dierent position, or moving
your listening position.
Other Issues
• Please email or call Technical Support if you
are having any other issue not listed here:
o mackie.com/suppor t-contact
o - 800-898-32
14
One side is way louder than the other!
• Are the level controls set the same for both channels
on the mixer and amplifier?
• Check the pan control on the signal source. It may
be turned too far to one side. If you’re using a stereo
signal source, it may be delivering an out-of-balance
stereo signal.
• Try switching sides: Turn o the amp, swap
the speaker cables at the amp and turn the amp
back on. If the same side is still louder, the problem
is with your speaker cabling or the loudspeakers.
If the other side is louder now, the problem is with
the mixer, the loudspeaker processor, the amp,
or the line-level cabling.
