How to Use This Manual:

Afer this introduction, a getting started guide will help

you get things set up fast. The hookup diagrams show some
typical DRM loudspeaker setups, including some that involve

DRM Professional Powered Loudspeaker Series

the DRM8S subwoofer.

This icon marks information that is critically
important or unique! For your own good, read and
remember them...it is a good idea to pay special
attention to these areas in the Owner’s Manual
marked with the “VERY IMPORTANT” hand icon.

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. If not using a subwoofer, connect the outputs from

the mixing console (or other signal source) to the inputs
on the rear panel of the loudspeakers.

3. If using a subwoofer, connect the outputs from

the mixing console (or other signal source) to the inputs
on the subwoofer, then connect the high pass outputs
from the subwoofer to the inputs of the loudspeakers.

4. Push the line cord securely into the subwoofer’s /

loudspeaker’s IEC connectors and plug the other ends into
grounded AC outlets. The subwoofer/loudspeaker may accept
the appropriate voltage as indicated near the IEC connector.

5. Turn the mixer (or other signal source) on.

6. Turn the subwoofer on (if applicable).

7. Turn the loudspeakers on.

8. Make sure the loudspeaker’s channel levels are set

to (or near) 0 dB.

9. Start the signal source and raise the mixer’s main L/R

fader up to a comfortably loud listening level.

There’s an illustration of a microscope,
so, of course, you’re going to get more
detailed information when you see this little
guy. There are explanations of features
and practical tips listed here.

It’s a good idea to pay attention to text displayed
next to a note icon, as this icon draws attention
to certain features and functions relating to the
usage of the DRM Series.

Please write the serial numbers here for future reference
(i.e., insurance claims, tech support, return authorization,
make dad proud, etc.)

Date of purchase:

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, subwoofers next, and DRM loudspeakers
last. As such, the DRM loudspeakers should also be turned
o first, followed by the subwoofers, then 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.

DRM loudspeakers are the perfect tool for singer-songwriters touring the local coee shops. Bring your favorite axe
and mic, DRM loudspeakers and cables and power cords.

In this example, a dynamic microphone is connected to the channel  input of a DRM22 loudspeaker, used for monitoring
purposes.

Now grab your axe and plug it directly into the channel 2 input. Or if you use eects, connect the guitar to the eects input
and another cable from the eects output to the channel 2 input.

A DRM25 loudspeaker will be used for the main PA. Simply connect a cable from the DRM22 monitor’s MIX OUT jack
to the DRM25 PA’s channel  input.

For the output, you will want to set a speaker mode, described in detail on page 2. For this type of setup, Live works well
for the main DRM25. Select the Monitor mode for the DRM22 monitor. Additionally, you will want to set the monitor’s
configuration > channel 2 input to Hi-Z to account for the guitar.

DRM loudspeakers may be daisy-chained via the male XLR connector labeled “DIRECT OUT” (which sends only
the signal from the input located above it) or via the “MIX OUT” which outputs all inputs. Simply plug the signal
source (i.e., mixer output or microphone) into the input jack(s), and patch that loudspeaker’s direct out or mix
out jack to the next loudspeaker’s input jack, and so on, daisy-chaining multiple DRM loudspeakers. See above
for visual representations of daisy-chaining.

Here’s how to set up a large club system. In this example, the L/R outputs of a DL6S mixer are connected directly
to the CH inputs of a pair of DRM8S subwoofers. The Direct Out of each subwoofer is then connected to the inputs
of an additional pair of DRM8S subwoofers. The X-Over of these subwoofers may be set to DRM Top.

From here, the high-pass outputs of the two outer DRM8S subwoofers are connected directly to the inputs of a set
of DRM35 loudspeakers. The Speaker Modes of these PA loudspeakers may be set to Live (or Club) and the Subwoofer
HPF set to DRM Sub. Talk about beefy low end!

Outputs  and 2 from the mixer may be used as aux sends; these are connected directly to the CH inputs of a pair of DRM22
loudspeakers to be used as monitors for the band. The Speaker Modes of the monitor loudspeakers may be set to Monitor.

DRM Loudspeakers: Rear Panel Features

. Power Connection

This is a standard 3-prong IEC power connector.
Connect the detachable power cord (included in
the packaging with the loudspeaker) to the power
receptacle, and plug the other end of the power
cord into an AC outlet.

Make sure that the AC power is matched to
the AC power indicated on the rear panel
(below the IEC receptacle).

Disconnecting the plug’s ground pin is
dangerous. Don’t do it!

2. Power Switch

Press the top of this rocker switch inwards to turn
on the loudspeaker. Press the bottom of this rocker
switch inwards to turn o the loudspeaker.

As a general guide, the mixer (or other
signal source) should be turned on first,

subwoofers next, and loudspeakers last.
As such, the loudspeakers should also be turned
o first, followed by the subwoofers, then the mixer.
This will reduce the possibility of any turn-on or
turn-o thumps and other noises generated by any

DRM Professional Powered Loudspeaker Series

upstream equipment from coming out of the speakers.

4. Gain [Ch.  and 2]

The gain knobs adjust the input sensitivity
of the mic/line inputs. This allows signals from
the outside world to be adjusted to run through
each channel at optimal internal operating levels.

There is –
(o), ramping up to +50 dB of gain fully up (max).

If connecting mixer outputs to loudspeaker
inputs, set the gain knob to 0:00 [“U”]
for optimal sound and performance.

6. /8" Input [Ch. 3/4]

This input may accept a stereo /8" line-level signal
from a phone, tablet, MP3 player, or other signal
source.

NEVER connect the output of an amplifier
directly to this input jack. This could damage
the input circuitry.

7. Gain [Ch. 3/4]

This gain knob adjusts the input sensitivity
of the /8" stereo input. This allows signals from
the outside world to be adjusted to run at optimal
internal operating levels. It ranges from o (knob
fully down) up to max (knob fully up).

8. Mix Out

This is a male XLR-type connector that produces
the post-DSP mix – afer voicing mode and EQ, but
before the alignment delay – from all three input jacks
(with Ch. 3/4 mono-summed). Use it to daisy-chain
several DRM loudspeakers together o the same
signal source(s).

It is wired the same as the direct outputs as seen
to the lef.

5. Direct Out [Ch.  and 2]

This is a male XLR-type connector that produces
exactly the same signal that is connected to the input
jack located above it. Use it to daisy-chain several DRM
loudspeakers together o the same signal source(s).

They are wired as follows, according to standards

means that certain frequencies form a “hill” around

With too much EQ, you can really upset

Let’s talk about those meters now.
That is what’s called a “Real-Time Analyzer”

An RTA allow you to see what you hear so you
may easily locate and eliminate feedback and other
anomalies while seeing the EQ changes in real time.

Many audio signals are highly dynamic: music,
speech and even environmental noise contain
significant changes in spectral content as a function
of time. With a digital mixer, musicians and sound
engineers can save time setting up at shows by
recalling previous settings. The DRM’s RTA fits right
in with that, literally displaying frequencies, shortening
the time it takes to tune the main loudspeakers or stage
monitors during setup in a new room.

Protection Circuitry

DRM loudspeakers employ a built-in limiter for less
distortion at peak levels. A dynamic bass response
circuit provides optimal low frequency response regard­less of overall output level. Additional protection
includes automatic thermal shutdown should the amp
overheat. However, with Class-D amp technology, which
is highly-ecient, this should never be a problem.

The protection circuits are designed to
protect the loudspeakers under reasonable

and sensible conditions. Should you choose
to ignore the warning signs [e.g. excessive distortion],
you can still damage the speaker in the loudspeaker
by overdriving it past the point of amplifier clipping.
Such damage is beyond the scope of the warranty.

About – Displays the current information about your
loudspeaker, including the model, firmware and DSP
versions, temperature and favorite color. There is really
only one reason to go here and that is if you’ve been
directed so by Technical Support.

Limiting

The driver has its own compression circuit which
helps protect it from damaging transient peaks.
The compressor is designed to be transparent and
is not noticeable under normal operating conditions.

Overexcursion Protection

A subsonic filter circuit just prior to the power
amplifier prevents ultra-low frequencies from being
amplified. Excessive low-frequency energy can damage
the woofer by causing it to “bottom out,” also know
as overexcursion, which is equivalent to a mechanical
form of clipping.

Thermal Protection

All amplifiers produce heat. DRM loudspeakers are
designed to be ecient both electrically and thermally.
In the unlikely event of the amplifier overheating, a
built-in thermal switch will activate, muting the signal.

When the amplifier has cooled down to a safe
operating temperature, the thermal switch resets
itself, and the DRM loudspeaker resumes normal
operation.

18

DRM Professional Powered Loudspeaker Series

If the thermal switch activates, try turning down
the level control a notch or two on the mixing console
(or via the Speaker Control knob) to avoid overheating
the amplifier. Be aware that direct sunlight and/or
hot stage lights may be the culprit of an amplifier
overheating.

AC Power

Owner’s Manual

Placement

Be sure the DRM loudspeaker is plugged into
an outlet that is able to supply the correct voltage
specified for your model. It will continue to operate
at lower voltages, but will not reach full power. Be sure
the electrical service can supply enough amperage for
all the components connected to it.

We recommend that a sti (robust) supply of AC
power be used because the amplifiers place high
current demands on the AC line. The more power that
is available on the line, the louder the speakers will play
and the more peak output power will be available for
a cleaner, punchier bass. A suspected problem of “poor
bass performance” is ofen caused by a weak AC supply
to the amplifiers.

Never remove the ground pin on the power
cord or any other component of the DRM
loudspeaker. This is very dangerous.

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.

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.

The DRM22 and DRM25 have dual angle
pole-mounts for optimal coverage. The rear one
is a straight angle while the front is angled at a 7˚
downward tilt. Additionaly, these two models may
be laid out horizontally as monitors for the band
at a 50˚ angle (as seen below).

• 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.

The Running Man logo is rotatable for
when the DRM22 or DRM25 is used
as a monitor; you can also rotate it when
the DRM35 is flown horizontally!

As with any powered components, protect them from
moisture. Avoid installing the loudspeaker in places
exposed to harsh weather conditions. If you are setting
them up outdoors, make sure they are under cover if
you expect rain.

Room Acoustics

REARBOTTOMTOP SIDE

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).

DRM Professional Powered Loudspeaker Series

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.

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 either () the internal
delay processor via the speaker control knob (see
page 5), or (2) 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.)

Keep in mind that the speaker mode is another great
way to compensate for some of these issues. See page
2 for more information.

. The rigging methods and hardware that
meet static, shock, dynamic, and any other load
requirements for supporting the loudspeaker
from structure.

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.

Owner’s Manual

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 oer 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 0028272.

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.

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.

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 power

• Our favorite question: Is it plugged in? Make sure

the AC outlet is live [check with a tester or lamp].

• Our next favorite question: Is the power switch on?

If not, try turning it on.

• Make sure the line cord is securely seated in the line

cord socket and plugged all the way into the AC outlet.

• Is the power LED on the front panel illuminated?
If not, make sure the AC outlet is live. If so, refer
to “No sound” below.

DRM Professional Powered Loudspeaker Series

• The internal AC line fuse may be blown. This is not
a user serviceable part. If you suspect the AC line
fuse is blown, please see the "Repair" section next.

Noise

• Make sure all connections to the loudspeakers

are good and sound.

• Make sure none of the signal cables are routed near
AC cables, power transformers, or other EMI-inducing
devices.

• Is there a light dimmer or other SCR-based device
on the same AC circuit as the DRM loudspeaker?
Use an AC line filter or plug the loudspeaker into
a dierent AC circuit.

Hum

• Try disconnecting the cable connected to the input
jack. If the noise disappears, it could be a “ground
loop,” rather than a problem with the DRM
loudspeaker. Try some of the following troubleshooting
ideas:

• Use balanced connections throughout your
system for the best noise rejection.

• Whenever possible, plug all the audio
equipment’s line cords into outlets which share
a common ground. The distance between
the outlets and the common ground should
be as short as possible.

No sound

• Is the level knob for the input source turned all the way
down? Verify that all the volume controls in the system
are properly adjusted. Look at the level meter
to ensure that the mixer is receiving a signal.

• 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 suciently
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 oending switch.

• Has it shut down? Make sure there is at least six
inches of free space behind each DRM loudspeaker.

Poor 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.

• Please email or call Technical Support if you

are having any other issue not listed here:
