Thump12A • Thump15A Powered Loudspeakers
Introduction
Getting Started
Delivering proven, chest-thumping low-end
with Dynamic Bass Response™ technology in
all-new, professional enclosures, the 1300W Thump™
loudspeakers take the series to a whole new level.
The following steps will help you set up the loudspeakers quickly.
Get maximum versatility with built-in mixers and
application-specific speaker modes. And for maximum
room-shaking low-end, pair your Thump speakers
with the 1200W Thump18S Subwoofer.
Redesigned from the ground up, these are our most
flexible and powerful Thump loudspeakers ever with
the class-leading performance you need.
1. 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 using a subwoofer, connect the outputs
from the mixing console (or other signal source)
to the inputs on the loudspeaker, then connect
the mix out to the inputs of the subwoofers. Make
sure the subwoofer’s gain knob is set to “U” (unity gain).
3. 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.
4. Make sure the loudspeaker’s gain knobs are set
to (or near) “line”.
5. 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.
6. Turn the mixer (or other signal source) on.
7. Turn the subwoofer on.
8. Turn the loudspeakers on.
How to Use This Manual:
After this introduction, a getting started guide will
help you get things set up fast. The hookup diagrams
show some typical Thump12A and Thump15A setups,
including some that involve the Thump18S subwoofer.
This icon marks information that is critically
important or unique to the subwoofer. For
your own good, read and remember them.
9. Start the signal source and raise the mixer’s
main L/R fader up to a comfortably loud listening level.
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 Thump loudspeakers last. As such, the Thump loudspeakers should also be turned off first, followed by the subwoofers, then the mixer. This will reduce the possibility of any turn-on or turn-off 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.

Hookup Diagrams
Thump loudspeakers are the perfect tool for singer-songwriters touring the local coffee shops.
Bring your favorite axe and mic, Thump loudspeakers and cables and power cords.
In this example, a dynamic microphone is connected to the channel 1 input of a Thump12A
loudspeaker, used for monitoring purposes. Be sure that the gain knob is set to “mic” in order to
get an extra boost for the mic. If anything other than a microphone is attached to a channel input,
make sure the gain knob is set to anything other than “mic” [“line” is a safe bet]. From there,
adjust the gain as described on page 11.
Now grab your axe and plug it directly into the channel 2 input. Or if you use effects, connect
the guitar to the effects input and another cable from the effects output to the channel 2 input.
Set the channel two gain knob to “line”.
Another Thump12A loudspeaker will be used for the main PA. Simply connect a cable from the Thump12A monitor’s MIX OUT jack to the Thump12A PA’s channel 1 input [gain knob set to “line”].
For the output, you will want to set a speaker mode, described in detail on page 11. For this type of
setup, Music works well for the main Thump12A. However, don’t count out the Live mode! It has a nice
low cut and a brilliant high end. Select the Monitor mode for the Thump12A monitor.

The level knob adjusts the overall signal level at the
input to the built-in power amplifiers. It ranges from Off
(– ) to MAX (maximum gain), with unity gain at the
center position (12 o’clock).
• Thump loudspeakers are designed to operate with
a +4 dBu signal when the main knob is at the center
position.
• Thump loudspeakers may accept up to a +20 dBu
signal by turning down the main knob accordingly. Turning the main knob past center position will provide
enough gain to connect a microphone directly.

8. Main LED Switch / Limit LED
The LED on the front of the Thump loudspeaker
illuminates when this switch is disengaged and
AC power is available at the mains input. Engage
the switch if you do not want the front panel LED
to illuminate.
Thump loudspeakers have a built-in limiter that
helps to prevent the amplifier outputs from clipping
or overdriving the transducers. The limit indicator
illuminates amber when the limiter is activated.
It’s okay for it to blink yellow occasionally, but if it
blinks frequently or lights continuously, turn down
the gain knob(s) until it only blinks occasionally.
Excessive limiting may lead to overheating,
which in turn trips the thermal protect
circuitry and interrupts the performance.
See ‘Thermal Protection’ to the right for more
information.
Protection Circuitry
Thump 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-efficient, 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.
All amplifiers produce heat. Thump loudspeakers are
designed to be efficient 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 Thump loudspeaker resumes normal
operation.
If the thermal switch activates, try turning down
the level control a notch or two on the mixing console
(or the back of the loudspeaker) 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
Be sure the Thump 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 stiff (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 often caused by a weak AC supply
to the amplifiers.
Never remove the ground pin on the power
cord or any other component of the Thump
loudspeaker. This is very dangerous.
Limiting
Care and Maintenance
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.
Your Thump loudspeakers will provide many years of
reliable service if you follow these guidelines:
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.
12
Thermal Protection
Thump12A • Thump15A Powered Loudspeakers
• 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 15 minutes prior
to high-power operation.
• Use a dry cloth to clean the cabinets. Only do
this when the power is turned off. Avoid getting
moisture into any of the openings of the
cabinet, particularly where the drivers are
located.
Room Acoustics
Thump 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 SPM200 is a great
option when using a subwoofer.
Thump loudspeakers are designed to sound fantastic
in nearly every application.
WARNING: These Thump loudspeakers do
not have rigging points and are not suitable
for rigging. NEVER attempt to suspend
a Thump 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.
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.
Thump loudspeakers are NOT designed to array
horizontally. If you feel you must put two speakers
side-by-side, you should have a good understanding
of the relationship between the splay angle (the angle
between the facing sides of the cabinets) and frequency
cancellation effects between cabinets.
When two cabinets are positioned side-by-side
such that the rear-angled faces of the enclosures
are parallel, the splay angle will be 90º. This matches
the 90˚ horizontal coverage pattern of each individual
loudspeaker; the interference between the two cabinets
will be minimized, but the total coverage of 180˚ may
be too wide for some applications. The mid and high
frequencies may also be reduced for those in the center
who are too close to the loudspeakers.
Reducing the splay angle will reduce the total
horizontal coverage, but it also creates an area both
speakers are covering. Instead of a nearfield hole,
this will cause comb-filtering effects in the frequency
response in the overlapping area. The smaller the splay
angle, the more energy will be delivered on-axis, but the comb-filtering effects will get worse at the same time.
To reiterate, though, we strongly suggest
NOT arraying these loudspeakers horizontally.
Experimentation and experience will help you find
the right balance for your application.
But, room acoustics play a crucial role in the overall
performance of a sound system. However, the wide
high-frequency dispersion of the Thump 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 highfrequency 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 off 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 100 feet, you should use a
delay processor to time-align the sound. (Since
sound travels about 1 foot per millisecond, it
takes about 1/10 of a second to travel 100 feet.)
Keep in mind that the speaker mode is a great way
to compensate for some of these issues. See page 11 for
more information.

If you think your Thump 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
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.
Noise
No power
• Our favorite question: Is it plugged in? Make sure the AC outlet is live [check with a tester or lamp].
• What is the position of the gain knob? It should
be at (or near) “mic” when a mic is connected
and at (or near) “line” when a line-level signal
is connected. It should be “off” for all unused inputs.
• Our next favorite question: Is the power switch on? If not, try turning it on.
• Make sure all connections to the active loudspeakers are good and sound.
• Make sure the line cord is securely seated in the line cord socket and plugged all the way into the AC outlet.
• Make sure none of the signal cables are routed near AC cables, power transformers, or other EMI-inducing devices.
• 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.
• Is there a light dimmer or other SCR-based
device on the same AC circuit as the Thump loudspeaker? Use an AC line filter or plug the loudspeaker into a different AC circuit.
•
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.
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 sufficiently 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 offending switch.
• Has it shut down? Make sure there is at least six inches of free space behind each Thump loudspeaker.
Owner’s Manual
Appendix A: Service Information
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 Thump 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.
