20. NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from

• Consult the dealer or an experienced radio/TV technician for help.
CAUTION: Changes or modifications to this device not expressly
approved by LOUD Technologies Inc. could void the user's authority to
operate the equipment under FCC rules.
21. This apparatus does not exceed the Class A/Class B (whichever is
applicable) limits for radio noise emissions from digital apparatus as
set out in the radio interference regulations of the Canadian Department
of Communications.
ATTENTION — Le présent appareil numérique n’émet pas de bruits
radioélectriques dépassant las limites applicables aux appareils
numériques de class A/de class B (selon le cas) prescrites dans le
réglement sur le brouillage radioélectrique édicté par les ministere des
communications du Canada.
22. Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise 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:

Before you begin, please make sure you read the
Safety Instructions on page 2 and Getting Started
on page 4.
Your new Mackie TH-15A powered loudspeakers
are designed to set up quickly and operate easily.
We know it’s often seen as a sign of weakness to
read a manual, along with asking for directions
when lost, but we hope you will read the rest of the
manual, at least while nobody is looking.
It is important to keep your receipt in a
safe place, and not a bad idea to write your
product information below for future reference
(i.e., insurance claims, tech support, return
authorization, etc.).
Please write the serial number for your TH-15A here
(or for both TH-15As if you have two) for future reference (i.e.,
insurance claims, tech support, return authorization, etc.):

Getting Started
The following steps will help you set up your
loudspeakers quickly.
INITIAL SETTINGS:
1. Turn the LEVEL control on the rear panel all the
way down.
2. Set the EQ ON/OFF switch out (OFF).
3. Turn the POWER switch OFF.
CONNECTIONS:
1. Connect the line-level signal from your mixer (or
other signal source) to the INPUT jack on the TH15A rear panel (XLR connector).
2. Connect the supplied AC power cord to the IEC
socket on the back of the loudspeaker. Plug the
other end into an AC outlet properly configured with
the correct voltage as indicated just below the IEC
socket.
TURN IT ON:
1. Turn the POWER switch ON.
2. Start your signal source (mp3 player, CD, DAW,
band, or whatever), but leave the master level
control on your mixer down.
3. Slowly turn up the LEVEL control on the TH-15A to
the “U” (unity gain) mark at the center position.
4. Adjust the master volume on your mixer to a
comfortably loud listening level. If the volume from
the speakers gets really loud, really fast, try turning
down the LEVEL control on the TH-15A a bit. If the
speakers don’t get loud enough, turn up the LEVEL
control to achieve a good balance of master volume
control and loudness from the speaker.
4
Now that you have your loudspeakers working, it’s
time to hunker down and read the rest of this manual…
especially the following:
ADDITIONAL TIDBITS OF WIDSDOM:
• Never listen to loud music for prolonged periods.
Please see the Safety Instructions on page 2 for
information on hearing protection.
• When you shut down your equipment, turn off the
TH-15A loudspeakers first to prevent thumps
and other noises generated by any upstream
equipment from coming out the speakers. When
powering up, turn on the TH-15As last.
• Save the shipping boxes and packing materials!
You may need them someday. Besides, your
cat 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.
• Record the serial number in the space provided on
page 3, along with where and when you bought it.
Introduction
The Mackie TH-15A Powered Loudspeaker delivers a chest-pounding 400W of peak system power via ultraefficient Class-D amplification. This means more power with less weight, perfect when portability matters. The 15”
high-precision woofer provides punchy low-end and responds quickly to transients. Hey, it’s called a THUMP, right?
An integrated 3-band contour EQ with a sweepable mid-frequency lets you dial in the perfect tone for your
application and even allows you to correct common room anomalies. The XLR input handles both mic and line level
signals, so you can just hook up a mic and be heard, assuming you have something to say. There’s even an XLR Thru
that allows you to easily “daisy chain” multiple TH-15As for increased coverage.
The TH-15A harnesses Mackie’s Active technology, including transducer time alignment, phase correction and
precision crossovers, maximizing the potential of every component. The THUMP is truly greater than the sum of its
parts.
Convenient top and side handles are integrated into the rugged, impact-resistant polypropylene enclosure,
providing a PA solution that is as durable as it is portable. And at only 36 lbs, it’s a breeze to pole-mount on a tripod
or atop a subwoofer.
Mackie TH-15A “THUMP” — High-performance audio without the high price tag.

The left and right line-level outputs from a
mixer feed the inputs of two Mackie TH-15A
Powered Loudspeakers. Their respective THRU
jacks feed the inputs of another pair of Mackie
TH-15A Powered Loudspeakers.

For microphone connections, you can daisy-chain
up to two TH-15As using the THRU jack, as shown.
Take great care to point any microphones away
from the loudspeakers. Otherwise, feedback may
occur.

This is where you connect AC power and your
signal to the loudspeaker and make adjustments to
the frequency response of the speaker to match the
loudspeaker’s location and your room’s environment.
1. INPUT
This is a female XLR-type connector that accepts a
balanced mic or line-level signal from a mixing console
or other signal source. For small gigs, simply connect a
microphone directly and adjust the LEVEL accordingly.
2. THRU
This is a male XLR-type connector that produces
exactly the same signal that is connected to the input
jack. Use it to daisy-chain several TH-15A’s together off
the same signal source.

THRU
INPUT

3. LEVEL
The LEVEL control 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).
• The TH-15A is designed to operate with a +4
dBu signal when the LEVEL control is at the U
(center) position.
• The TH-15A can accept up to a +20 dBu signal
by turning down the LEVEL control accordingly.
Turning the LEVEL past unity will provide enough
gain to connect a microphone directly.
• NEVER connect the output of an amplifier directly
to the input of the TH-15A. This could damage the
active input circuitry of the loudspeaker.
4. OL Indicator
8. LOW EQ
The OL (overload) indicator lights when the
amplifiers in the TH-15A are near the clipping point. It
is okay if the OL indicator blinks occasionally, because
this means that the transient peaks are just reaching
the maximum output of the amplifiers and you are
getting the most from your TH-15As.
This control gives you up to 15 dB of boost or cut
below 80 Hz and it is also flat at the center position
(U). This frequency range represents the punch in bass
drums, bass guitar, fat synth patches, and some really
serious male singers.
If the OL indicator is blinking frequently or lighting
continuously, turn down the LEVEL control [3] on
the TH15A or turn down the signal at it source (e.g.,
the mixing console) until the OL indicator blinks
occasionally or not at all.
9. EQ ON/OFF Switch
This switch allows you to bypass the EQ section.
When the switch is out (OFF), the EQ section is
bypassed and the EQ knobs have no effect on the signal.
When the switch is pushed in (ON), the EQ controls can
be used to tailor the frequency response of the TH-15A.
5. HIGH EQ
This control gives you up to 15 dB boost or cut above
12 kHz. The circuit is flat (no boost or cut) at the
center position (U). Use it to add sizzle to cymbals,
and an overall sense of transparency or edge to the
keyboards, vocals, guitar, and bacon frying. Turn it down
a little to reduce sibilance, or to remove high frequency
hiss.
6. MID EQ
This is a midrange EQ control that provides 15 dB
of boost or cut centered at any frequency between 100
Hz and 8 kHz. The MID EQ circuit is flat (no boost or
cut) at the center position (U). This frequency range
includes most vocals (male at the lower end of the
range and female at the upper end of the range), and
the fundamentals and harmonics for many instruments.
10. POWER Switch
Use this switch to turn the TH-15A loudspeaker on
and off. The indicating LED above the POWER switch
lights when the POWER switch is on and AC power
is available at the linecord socket. A second power
indicator is located on the front of the cabinet.
11. Line Cord Socket and Fuse
Connect the detachable line cord to this IEC socket
securely, and plug the other end into your AC outlet.
Make sure the AC power is matched to the AC power
indicated on the rear panel (under the IEC socket).
The fuse is located behind the fuse cover, at the
bottom of the IEC socket. See the “Troubleshooting”
section on page 11 for information about replacing the
fuse.
7. MID FREQ
This knob ranges from 100 Hz to 8 kHz and
determines the center frequency for the MID EQ filter.
This allows you to zero in on the precise narrow band of
frequencies you want to have affected by the MID EQ.
9
Protection Circuits
There are several protection mechanisms designed
into the TH-15A to safeguard the loudspeakers and
amplifiers from inadvertent damage.
CAUTION: The protection circuits are
designed to protect the loudspeakers under
reasonable and sensible conditions. Should
you choose to ignore the warning signs
(i.e., frequent OL LED indications, excessive distortion),
you can still damage the speakers in the TH-15A by
overdriving them past the point of amplifier clipping. Such
damage is beyond the scope of the warranty.
Overexcursion Protection
A 12 dB/octave high-pass filter at 40 Hz just prior
to the low-frequency amplifier prevents very low
frequencies from being amplified. Excessive lowfrequency energy below 40 Hz can damage the woofer by
causing it to “bottom out,” also known as overexcursion,
which is equivalent to a mechanical form of clipping.
Thermal Protection
All amplifiers produce heat. The TH-15A is designed
to be efficient both electrically and thermally.
The amplifier module is mounted on a large
heatsink, which is cooled by convection where cool air
is drawn over the rear panel, carrying the heat away.
In order for this convection cooling to work efficiently,
it is important to provide adequate airspace behind
the loudspeaker. When you position the TH-15A, we
recommend leaving at least six inches of air space
behind it.
• If for some reason the internal temperature
gets too hot, a built-in thermal switch activates
and turns off the amplifier. This protection
operates independently for the low-frequency and
high-frequency amplifiers. Therefore, it is possible
for only the low frequency or high frequency
amplifier to shut down while the other remains on.
• When the amplifier cools down to a safe
temperature, the thermal switch resets
and normal operation resumes.
10
• If the internal temperature again gets too hot,
the shutdown process repeats. Should this
happen, make sure that airflow to the rear of the
cabinet is not restricted. If the ambient air
temperature is very warm, try pointing a small
fan toward the rear panel to increase the airflow
through the fins.
Driver Protection
Each driver has its own compression circuit, which
helps protect them from damaging transient peaks. The
compressors are designed to be transparent and are not
noticeable under normal operating conditions.
Input Signal Wiring
You should use high-quality, shielded cable to
connect the signal source to the INPUT jack on the
TH-15A.
• High quality microphone cables work well.
• Foil shielded cables are commonly used for audio
wiring.
• 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. You can purchase quality
cables from your Mackie dealer.
Placement
The TH-15A loudspeaker is designed to sit on the
floor or stage. It can 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 TH-15A.
WARNING: The cabinet has no rigging
points and is not suitable for rigging.
NEVER attempt to suspend the TH-15A by
its handles.
As with any powered components, protect them from
moisture. If you are setting them up outdoors, make
sure they are under cover if you expect rain.
Appendix A: Service Information
If you think your Mackie product 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) to get some
ideas or contact our technical support heroes. You may
find the answer to the problem without having to send
your Mackie product away.
If two fuses blow in a row, then something is very wrong.
Try a different outlet in a totally different location. If fuses
continue to blow, see the “Repair” section on the next page
to find out what to do.
Troubleshooting
No Sound
No Power
• Our favorite question: Is it plugged in?
• Make sure the line cord is securely seated in the
line cord socket and plugged all the way into the
AC outlet.
• Make sure the AC outlet is live (check with a
tester or lamp).
• Is the POWER switch in the ON position?
• Are the power LEDs on the front and rear panel
illuminated? If not, make sure the AC outlet is
live. If so, refer to “No Sound” below.
• If the power LEDs are not illuminated, and you
are certain that the AC outlet is live, it is possible
the fuse has blown.
To remove and replace the fuse:
1. Disconnect the power cord from the IEC socket.
2. Remove the fuse drawer by prying it open with
a small screwdriver. It will slide all the way out.
4. Replace the fuse drawer by pushing it all the way
back into the IEC socket.
• Are the power LEDs on the front and rear panel
illuminated?
• Is the LEVEL control turned up?
• Is the signal source turned up? Make sure the
signal level from the mixing console (or whatever
device immediately precedes the loudspeaker) is
high enough to produce sound.
• If it’s a stereo pair, try switching them around.
For example, if a left speaker is presumed dead,
switch the left and right cords at the speakers. If
the problem switches sides, it’s not the TH-15A. It
could be a bad cable, or no signal from the mixer.
Bad Sound
• Is the input connector plugged completely into
the IN jack?
• Is something connected to the THRU jack? Try
unplugging it. If the sound improves, whatever
was plugged into the THRU jack may have
affected the signal.
• 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 loudspeaker.
FUSE
3. Remove the fuse and replace it with an
equivalent-type fuse.
115 VAC unit: 6.3 amp slo-blo (T6.3AL/250 V)
230 VAC unit: 3.15 amp slo-blo (T3.15AL/250 V)
• 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
different position, or moving your listening
position.
11
Noise/Hum
• Check the signal cable between the mixer and
the loudspeaker. Make sure all connections are
secure. These problems usually produce crackling
noises or hum.
• If you are using two or more TH-15A powered
loudspeakers, try plugging them all into the same
AC outlet panel or outlet strip. The purpose for
this is to connect them all to the same earth
ground point and reduce the possibility of creating
a ground loop.
Appendix B: Connections
XLR Connectors
XLR connectors are used to make balanced input
and through connections to the TH-15A. They are wired
as follows, according to standards specified by the AES
(Audio Engineering Society).
HOT
• If connecting an unbalanced output to the TH-15A
balanced input, make sure the shield is connected
to the unbalanced ground and to pin 1 of the XLR.
