Introduction
Getting Started
The new Thump Loudspeakers are the next evolution
of the incredibly popular series, packed with more power,
capability, and bang-for-the-buck than ever before.
Completely redesigned from the ground up, Thump features
heavy-duty drivers, 1400W amplifiers, and powerful tools
to make your next gig easier than ever.
Now equipped with a Feedback Eliminator plus a Music
Ducking mode, Thump keeps the show running smooth
when it counts.
Add in ultra-versatile I/O, legendary Thump sound quality,
and easy portability, Thump is going to be your new favorite
loudspeaker.
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 typical Thump loudspeaker setups.
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. Give a virtual high-five to your favorite live sound engineer.
6. Turn the mixer (or other signal source) on.

Purchased at:
Date of purchase:
7. Turn the subwoofer on (if applicable).
8. Turn the loudspeakers on.
9. Make sure the loudspeaker’s channel gain knob(s)
are set to mic or line.
0. Be sure that the volume of the input is the same
as it would be during normal use.
. 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
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.

Thump loudspeakers are the perfect tool for singer-songwriters touring the local coee shops. Bring your favorite axe
and mic, Thump loudspeakers and cables and power cords.
In this example, a Mackie EM-89D microphone is connected to the channel input of a Thump loudspeaker, used
as the main PA. The Channel gain knob should be set to Mic. The Mic/Line switch should be ENGAGED [Mic], as well.
Now grab your axe and plug it directly into the channel 2 input. Or if you use eects, connect the guitar to the eects
input and another cable from the eects output to the channel 2 input. Note that the gain knob is set to Line.
An additional Thump loudspeaker will be used for monitoring purposes. Simply connect a cable from the Thump PA’s
THRU jack to the Thump monitor’s channel input. This gain knob should also be set to Line.
Keep in mind that these “MIC” and “LINE” markings are for reference only and may need to be raised or lowered.

Perhaps you’re a DJ playing bumpin’ tunes in the middle of the night to a crowd that’s groovin’
and dancin’ to your fine selection.
In this example, a laptop is connected to the inputs of two Thump8S subwoofers.
The High-Pass Out of each subwoofer is then connected to the input of each Thump25 loudspeaker.
Additionally, a set of Mackie MC-450 headphones is connected to the phones jack of the laptop.
The gain knob on both loudspeakers should be set to Line. The Mic/Line switches should be disengaged [Line], as well.
Additionally, you will want to set the subwoofer’s High Pass Mode to either Flat or Deep. Keep in mind that these “MIC”
and “LINE” markings are for reference only and may need to be raised or lowered.

Thump loudspeakers may be daisy-chained via the “THRU” jack 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 mix out jack to the next loudspeaker’s
input jack, and so on, daisy-chaining multiple Thump loudspeakers. See above for visual representations of daisy-chaining.
NOTE: Make sure to set the gain knob(s) correctly. In the top diagram, all input channes are set to “LINE” and in the bottom
diagram, input channel of the first Thump is set to “MIC”, but the remaining ones should be set to “LINE”. Keep in mind
that these “MIC” and “LINE” markings are for reference only and may need to be raised or lowered.

Here’s how to set up a large club system. In this example, the L/R outputs of a DL6S mixer are connected directly
to the channel A inputs of a pair of Thump8S subwoofers. The Full Range Out of each subwoofer is then connected
to the inputs of an additional pair of Thump8S subwoofers.
From here, the High Pass Out of the two outer Thump8S subwoofers are connected directly to the inputs
of a set of Thump25 loudspeakers. Then set the subwoofer’s High Pass Mode to Deep. Talk about beefy low end!
Outputs and 2 from the mixer may be used as aux sends; these are connected directly to the channel inputs of a pair
of Thump25 loudspeakers to be used as monitors for the band. The gain knob on all Thump loudspeakers in this example
should be set to Line. Lastly, all Mic/Line switches should be disengaged [Line]. Keep in mind that these “MIC” and “LINE”
markings are for reference only and may need to be raised or lowered.

2. Power Switch
Press the right side of this rocker switch inwards
to turn on the loudspeaker. Press the lef side 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
upstream equipment from coming out of the speakers.

4. /8" Input Jack [Ch. 2]
This input channel may accept an /8" line-level
signal from a phone, tablet, MP3 player, or other signal
source.
NEVER connect the output of an amplifier
directly to a Thump input jack. This could
damage the input circuitry.
The /8" line-level connection may
be used simultaneously with channel
2’s combo jack – XLR or /4".
In other words, if there is a physical connection
to the /8" line input and another physical
connection to the combo jack, none of those
inputs will be interrupted. An easy way to look
at it is... there are extra inputs! The /8" line-level
connection and XLR (or /4") connection sum
together and do not override each other.
5. Mic / Line Switch [Ch. ]
Because an XLR connector may be connected
to a mic or an instrument, this switch adjusts
the channel’s input sensitivity to optimize channel
for mic or line-level signals. If a mic is connected,
this switch should be engaged and the gain knob –
more below – set to mic. If an instrument is connected
to channel (via XLR), this switch should be
disengaged and the gain knob set to line.
7. Thru Jack
This is a male XLR-type connector that produces
the mix from the input jacks. Use it to daisy-chain
several Thump loudspeakers together o the same
signal source(s).
They are wired as follows, according to standards
specified by the AES (Audio Engineering Society):

Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)

6. Gain Knobs [Ch. and 2]
If you haven’t already, please read the “Quick Start”
section on page 4. Setting the gain correctly will ensure
that the preamplifier’s gain is not too high, where
distortion could occur, and not too low, where
the quieter, exquisitely-delicate passages might
be lost in background noise.
The gain knobs allow signals from the outside world
to be adjusted to run through each channel at optimal
internal operating levels.
If connecting mixer outputs to Thump inputs, set the
gain knobs to 9:00 [“LINE”] for optimal sound and
performance.
Keep in mind that these “MIC” and “LINE”
markings are for reference only and may
need to be raised or lower.

8. Main Volume Knob
The volume knob adjusts the overall signal level
at the input to the built-in power amplifiers.
It ranges from O (– ) to MAX (maximum gain).
• Thump loudspeakers are designed to operate
with a +0 dBu signal when all knobs are at
the center position.
• Thump loudspeakers may accept up to a +20 dBu
signal by turning down the channel gain in line mode.
• Turning the main knob past center position will
provide enough gain to connect a microphone directly.
Most microphones will want the knob somewhere
around the 9:00 position. For safety, if you’re plugging
in a mic, start with the volume o and gradually
rotate it clockwise until you achieve the desired
volume... and be on the lookout for the dreaded
shriek of the feedback monster.

9. Sig/OL LED
This dual-colored LED will illuminate green
when the input signal is present, indicating signal.
Thump loudspeakers have a built-in limiter that
helps to prevent the amplifier outputs from clipping
or overdriving the transducers. The LED illuminates
red when the limiter is activated. It’s okay for it to blink
red occasionally, but if it blinks frequently or lights
continuously, turn down the gain knob 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’ on page 4 for more information.
0. Music Ducking
Have you been to an event where music was playing,
then when someone spoke into the mic, that the music
volume decreased greatly (but was still there)? That’s
called “music ducking”!
When the music ducking switch is engaged,
the channel 2 level will decrease when a mic signal
is present on channel . As if by magic, once the
speaking is completed, the music will return back to its
previous level. True wizards, those engineers... and
Thump212 and Thump215 Powered Loudspeaker Series
none of them have long grey beards, robes and pointy
hats.
. Feedback Eliminator
The multi-band feedback eliminator hunts
down oending feedback frequencies and applies
up to six notch filters automatically to destroy
feedback and maximize gain prior to feedback.
This is a great tool for when an engineer is not present.
• O [Default] – The feedback eliminator is not
engaged. If filters have been applied, this setting will
retain its current filter settings if there are any, but they
will not be engaged until it is turned back on.
• On – When the automatic feedback eliminator is
turned on, scanning occurs continuously. The six filters
will engage sequentially when feedback is present until
all are used and then it will be locked. If feedback is
identified on an existing filter, the notch will deepen in
three steps to further destroy the oending feedback
frequency. Pretty cool, huh?
The feedback eliminator ONLY aects
channel (mic and line mode).

2. Fan On / O
One of our favorite things about the Thump Series
is the Summer cool-o / Winter warm-up feature.
Is it hotter than the blazes out where you are?
We’ve got you covered!
Simply press this switch to turn the fan on and o.
The speaker begins acting like a fan, blowing out cool
air!
The LED will illuminate green when engaged (fan on).
3. Fan Speed
Want more? Of course you do! Here you’re able to
select the speed setting of the fan from (the lowest
setting) to 5 (the highest setting).
Quickly press this button to what setting you
would like, up to five times. The LED will flash green
the number of the current setting.
5. Heat On / O
The fan feature is nice... but what if it’s 40˚ below with
20 feet of snow outside and a wind chill factor of the
frozen tundra? Yeah, we’ve got you covered there, too!
The built-in heater is great, especially when in the
monitor position. Gotta love warm tootsies! Just like
with the fan, simply press this switch to turn the heat
on and o. The LED will illuminate green when engaged
(heat on).
6. Heat Level
If the temperature is the aforementioned “frigid”,
we’re pretty confident that you’re going to want
to crank the heat... perhaps not, but we’d bet on it!
This works similarly to that of the fan speed
with settings ranging from (low heat) to 5
(cranked heat). Quickly press this button to what
setting you would like, up to five times. The LED
will flash green the number of the current setting.
4. Mist Level
A rotating fan with multiple speeds is a nice feature,
but when a mister is thrown in...? Oh, all bets are o!
When the mist level switch is engaged, a light spray
of water is dispersed to keep the band and crowd nice
and refreshed throughout the performance. The LED
will illuminate green when engaged (mist on).

Last, but absolutely not least... the fan AND heater are
both rotatable (although the one switch controls whichever one is engaged, of course).
The rotation speed may be set to (low), 2 (medium),
or 3 (high). As with the fan speed and heat level,
quickly press this button to what setting you would
like, up to three times. The LED will flash green
the number of the current setting.
Please note that the rotation function only
works when the loudspeaker is mounted
on the T00 tripod or SPM400 pole mount.

Protection Circuitry
AC Power
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-ecient, 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 woofer in the loudspeaker
by overdriving it past the point of amplifier clipping.
Such damage is beyond the scope of the warranty.
Limiting
The polymer high frequency 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.
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 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 ofen 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.
Care and Maintenance
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
Thump212 and Thump215 Powered Loudspeaker Series
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. Thump loudspeakers
are designed to be ecient 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
to avoid overheating the amplifier. Be aware that direct
sunlight and/or hot stage lights may be the culprit
of an amplifier overheating.
Your Thump 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.

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.
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 T00 is a great tripod option and the SPM400
is a nice choice when using a subwoofer.
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.
Thump loudspeakers may be laid out horizontally as
monitors for the band at a 40˚ angle (as seen below). It
is intended to be used only when the speaker is in its
wedge configuration and works best when on a hard
work surface, like a stage.
Owner’s Manual
Room Acoustics
Thump 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 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 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.
As seen above, the Running Man logo is rotatable
for when the loudspeaker is used as a monitor!
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.)

Appendix A: Service 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
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.
• 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 loudspeaker?
Use an AC line filter or plug the loudspeaker into
a dierent 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 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
Thump212 and Thump215 Powered Loudspeaker Series
• 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 suciently
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.
• Has it shut down? Make sure there is at least six
inches of free space behind each 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.
