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.

What me, read a manual?
Before you begin, please make sure you read the Safety Instructions on page 2 and
Getting Started on page 4.
Your new TAPCO® TH-15A active 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 here 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 DIRECT/EQ switch out (DIRECT).
3. Turn the POWER switch OFF.
CONNECTIONS:
1. Connect the line-level signal from your mixer (or
other signal source) to the IN jack on the TH-15A
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 (tape deck, CD, DAW, 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-15As 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.
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
Thank you for choosing the TAPCO TH-15A active loudspeakers. The TAPCO product
line hails back to the days of TAPCO Corporation, Greg Mackie’s first company. TAPCO
revolutionized the audio industry back in 1969 with the very first 6-channel mixer specifically
designed for keyboards and rock ‘n’ roll.
In essence, TAPCO redefined the price/performance ratio and made high-quality
professional audio equipment accessible to virtually anyone. Today, TAPCO is reborn
with the same ideals and is backed by the world-class engineering and manufacturing
horsepower of LOUD Technologies.
These versatile compact loudspeakers can be used in a variety of applications. The
durable, lightweight enclosure is designed with a socket in the bottom for pole-mounting.
In addition, it can be placed on its side as a floor monitor.
The TH-15A active loudspeakers are packed with features and designed to produce
transparent and uncolored sound for PA systems and sound reinforcement. The two-way bass
reflex (ported) design provides an amazingly flat frequency response from 40 Hz to 20 kHz.
There are many benefits to integrating an active crossover, power amplifiers, and drivers
into a single cabinet, and we’ve taken full advantage of these benefits in the design of
the TH-15A.
• The crossover point is designed so that the high and low-frequency drivers are fed only
the frequencies that they are best able to reproduce.
• The amplifiers are designed to provide maximum acoustic output from the speakers, yet
minimize the danger of speaker damage due to overdriving.
• The connecting wire between the amplifier outputs and the drivers are kept to an
absolute minimum so the damping factor of the amplifier isn’t compromised by the
resistance of long speaker cables.
• The acoustic sum of the outputs from the two drivers are optimized electronically, as well
as physically, so the amplitude response is unity and the phase difference is minimal.
In short, all the complex interconnected components in the system are designed to work
in harmony with each other to produce the best possible sound.
Here’s a quick look at all the features packed into the TH-15A loudspeakers:
• Flat frequency response (–10 dB, 40 Hz to 20 kHz)
• LF equalization provides ±15 dB at 80 Hz and below
• 1” high-frequency compression driver
• 15” low-frequency woofer
• MF equalization provides ±15 dB with sweepable
frequency from 100 Hz to 8 kHz
• Convenient portable design, with integrated
handles in both sides and top
• HF equalization provides ±15 dB at 12 kHz and
above
• Ported, bass reflex design for enhanced bass
performance
• EQ bypass (DIRECT) switch
• 99 watt HF and 298 watt LF power amplifiers (peak)
• Pole-mount socket
• Rear panel power switch
• Low-frequency over-excursion protection
• High-strength lightweight cabinet constructed of
polypropylene
• High-density adiabatic fiberfill absorbs internal
reflections
• Balanced Mic/Line XLR input and thru connectors
• 24 dB/octave crossover at 3 kHz
• Adjustable input level control

TAPCO TH-15A Features
REAR PANEL DESCRIPTION
5. HIGH EQ
This control gives you up to 15 dB boost or cut
above 12 kHz, and it is also flat 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 hide tape hiss.
This is where you connect 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
6. MID EQ
This is a female XLR-type connector that accepts
a balanced mic or line-level signal from a mixing
console or other signal source.
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. 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
TH-15A
ACTIVE SOUND
instruments.
REINFORCEMENT LOUDSPEAKER
2. OUTPUT
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.
7. MID FREQ
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 INPUT
LEVEL control accordingly.

• 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
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.
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.

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.

EQ
This control gives you up to
15 dB of boost or cut below 80 Hz.
The circuit is flat (no boost or
cut) at the center position. This
frequency range represents
the punch in bass drums,
bass guitar, fat synth patches,
and some really serious male
singers.
9. DIRECT/EQ Switch
This switch allows you to bypass the EQ section.
When the switch is out (DIRECT), the EQ section is
bypassed and the EQ knobs have no effect on the
signal. When the switch is pushed in (EQ), the EQ
controls can be used to tailor the frequency response
of the TH-15As.
10. POWER Switch
Use this switch to turn the active loudspeakers 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 9 for information about replacing
the fuse.
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 through it’s fins, 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 heatsink 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 heatsink cools down to a safe
temperature, the thermal switch resets and normal
operation resumes.
• If the heatsink 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
heatsink 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 IN
jack on the TH-15A.
• Foil shielded cables, such as Belden 8451,
8761, or 9501 are commonly used for
studio wiring.
• Microphone cables work well.
• 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 TAPCO product has a problem,
please check out the following troubleshooting tips
and do your best to confirm the problem. Visit the “Talk
To Us” section of our website (www.tapcoworld.com)
to contact our technical support heroes and get some
ideas. You may find the answer to the problem without
having to send your TAPCO product away.
Troubleshooting
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.
No Sound
• 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 OUT jack?
Try unplugging it. If the sound improves, whatever
was plugged into the OUT 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.
• 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.
Noise/Hum
FUSE
3. Remove the fuse and replace it with an
equivalent-type fuse.
115 VAC unit: 3.15 amp slo-blo (T 3.15AL/250 V)
230 VAC unit: 2 amp slo-blo (T 2AL/250 V)
4. Replace the fuse drawer by pushing it all the
way back into the IEC socket.
If two fuses blow in a row, then something is very
wrong. See the “Repair” section on the next page
to find out what to do.
• 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 active
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.
• 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.
