Introduction

Getting Started

So, you need the sound of a powerful, professional

loudspeaker with the portability of a boom box?
Meet Thump GO; the take-it-anywhere, Bluetooth®
equipped, ultra-flexible, battery-powered loudspeaker.

Built to make your life a whole lot easier, Thump GO

oers lightning-fast setup and simple-yet-powerful
sound processing, plus flexible inputs, Bluetooth®
streaming, and wireless control via the Thump Connect 2 app.

Most importantly, Thump GO will amplify the real you

with clear, punchy, and accurate sound wherever you
call your stage. Take the performance of the renowned
Thump Series anywhere, with the Thump GO Portable
Battery-Powered Loudspeaker.

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 Thump GO loudspeaker setups, including
some that involve the Thump 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 Thump GO 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 gain knob(s)
are set to mic or line.

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 Thump GO.

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

Purchased at:

Date of purchase:

9. Be sure that the volume of the input is the same
as it would be during normal use.

0. 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 the Thump GO
last. As such, the Thump GO 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.

Hookup Diagrams

Owner’s Manual

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

In this example, a Mackie EM-89D dynamic microphone is connected to the channel  input of a Thump GO,
used for monitoring purposes. The gain knob should be set to mic and the mic/line switch engaged (mic).

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. The gain knob should be set to line and the mic/line
switch disengaged (line).

Another Thump GO loudspeaker will be used for the main PA. Simply connect a cable from the Thump GO monitor’s
THRU jack to the Thump GO PA’s channel  input.

For the output, you will want to set a voicing mode, described in detail on page 0-. For this type of setup, ‘Music’
works well for the main Thump GO. Select the ‘Monitor’ mode for the Thump GO monitor.

Thump GO 8" Portable Battery-Powered Loudspeaker

Thump GO loudspeakers are great for house parties, BBQs, karaoke competitions and picnics, too!

In this example, we connected a Mackie EM-89D dynamic microphone to the channel  input of a Thump GO. The gain knob
should be set to mic and the mic/line switch engaged (mic). Additionally, a phone is connected to channel 2’s /8" input
for music playback. The gain knob of this input should be set to line. The volume of the phone should be up, as well.

Another Thump GO loudspeaker will be used for extra “punch”. Simply connect a cable from the first Thump GO’s
THRU jack to the other Thump GO’s channel  input. The gain knob of this input should be set to line.

For the output, you will want to set a voicing mode, described in detail on page 0-. For this type of setup, ‘Music’
works well for both Thump GO loudspeakers.

Now here’s where it could get interesting... I’m talkin’ cables, baby (or rather, the lack thereof). Cables may be accidentally
removed and/or intermittent (at best) and injury – even death (at worst) – could occur. All it takes is one person to catch
it on their foot and trip. Ah, how devastating, but... there are solutions!

First, we would suggest using the EleMent Wave XLR transmitter / receiver system. Now you have a wireless mic!
Next, instead of connecting the phone to the channel 2 /8" jack, just connect via Bluetooth. Boom, another cable gone!
The final cable is attached from the first Thump GO Thru output to the second Thump GO channel  input.
However, you can link the Thump GO loudspeakers together and set aside that third and final cable to go totally
wireless! Heck, if the batteries are charged, you won’t even need the power cables!

But wait, there’s more! Thump GO loudspeakers have three additional features that are worth discussing here: Outdoor Mode,
Music Ducking and Feedback Eliminator. Outdoor Mode may be engaged if one (or both) loudspeakers are outside.
Levels may be easily raised and lowered via the Thump Connect 2 App. Music Ducking should be engaged if someone
will be speaking while music is playing in the background. It should not be engaged during a karaoke battle royale, though.
Lastly, it’s always a good idea to engage the Feedback Eliminator. More information about all of these features (and then
some) may be found on the following pages.

In this example, a ProFX0v3 mixer is connected directly to two Thump GO loudspeakers. It is the perfect setup for a small
club. Simply connect the L/R outputs of the ProFX0v3 mixer to the channel  input of each Thump GO loudspeaker.
The gain knob on both should be set to Line. Don’t forget to set the Voicing Mode on both loudspeakers to ‘Music’!

are connected to the channel  inputs of a pair of Thump GO loudspeakers. The gain knob on both should be set to Line.
Here you will want to set the Voicing Mode to ‘Music’.

Thump GO 8" Portable Battery-Powered Loudspeaker

Thump GO loudspeakers may be daisy-chained via the male XLR connector labeled “THRU”. Simply plug the signal
source (i.e., mixer output or microphone) into the input jack(s), and patch that loudspeaker’s thru jack to the next
loudspeaker’s input jack, and so on, daisy-chaining multiple Thump GO 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 GO 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 lower.

With it, all of the hardware features listed here –
and more! – may be controlled remotely via Bluetooth
connection. The only thing the Thump Connect 2 App
can’t do is turn the Thump GO on and o.

. Power Connection

This is a standard 3-prong IEC power connector.
Connect the detachable power cord (included in
the packaging with the Thump GO) 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
(near the IEC receptacle).

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

2. Power Switch

Press the right side of this rocker switch inwards
to turn on the Thump GO. Press the lef side of this
rocker switch inwards to turn o the Thump GO.

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.

In addition to accepting a balanced mic signal
using an XLR connector, these input channels may
also accept /4" line-level signals driven by balanced
or unbalanced sources.

To connect balanced lines to these inputs, use
a /4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands
for Tip-Ring-Sleeve, the three connection points
available on a stereo /4" or balanced phone jack
or plug. TRS jacks and plugs are used for balanced
signals and are wired as follows:

/4" TRS Balanced Mono Wiring:

Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)

3. XLR and /4" Combo Input Jacks

Input channels  and 2 may accept a balanced XLR
connector. Both channels accept line-level inputs,
but only channel  accepts a mic. They are wired
as follows, according to standards specified by
the AES (Audio Engineering Society).

XLR Balanced Wiring:

Pin  = Shield (ground)
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)

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 GO’s 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" – and/or Bluetooth
connection. In other words, if there is a physical
connection to the /8" line input, another physical
connection to the combo jack AND a device is
connected via Bluetooth, 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.

Thump GO 8" Portable Battery-Powered Loudspeaker

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.

7. Thru Jack

This is a balanced male XLR-type connector
that produces a mono-summed pre-DSP mix
from all input jacks. It is not aected by the main
volume. Use it to connect an additional Thump GO
or subwoofer o of the same signal source.

It is wired as follows, according to standards
specified by the AES (Audio Engineering Society):

8. Main Knob

The level knob adjusts the overall signal level
at the input to the built-in power amplifiers.
It ranges from – (o, knob fully down) up
to max (+6 dB, knob fully up), with unity gain
at the center position (2 o’clock).

• Thump GO is designed to operate with a +4 dBu
average line signal when the main knob and the line
input gain are at the center position (unity).

• Thump GO may accept up to a +20 dBu line signal
by turning down the line input gain accordingly
(with the Ch.  mic / line switch disengaged – line).
If the overload LED illuminates, slowly turn down
the input gain until the warning disappears.

The gain knobs – in conjunction with the overload
LED – adjust the input sensitivity of the mic [Ch. ]
and line inputs. This allows signals from the outside
world to be adjusted to run through each channel
at optimal internal operating levels.

If the signal originates through the mic XLR jack,
there will be 0 dB of gain with the knob fully down,
ramping to 40 dB of gain fully up, with unity gain “U”
at 2:00.

Through the /4" line inputs, there is –20 dB
of attenuation fully down and +20 dB of gain fully
up, with unity gain “U” at 2:00.

If connecting mixer outputs to Thump GO
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.

Thump GO 8" Portable Battery-Powered Loudspeaker

• If the Ch.  mic / line switch is engaged [mic],
turning up the channel  gain knob will provide
enough gain to connect a microphone directly.
Start with the main at the center position,
and don’t be afraid to crank the channel  mic gain.

9. Voicing Modes

The voicing mode allows you to change the
Thump GO’s voicing to tailor it to best suit your
particular application. Press the voicing mode
button repeatedly until the LED of the voicing
mode you desire is illuminated.

The four speaker modes are as follows:

• MUSIC Voicing Mode – This mode is full range,
but focuses on increased bass and brilliant high
frequencies. This is the place to start for most DJ /
music playback applications.

• SPEECH Voicing Mode – This mode features
a significant low frequency roll-o to attenuate
low-end vocal boom. It also adds boost to high

Thump GO: Rear Panel Features continued...

Owner’s Manual

frequencies – critical for speech intelligibility – and
notches part of the spectrum where feedback squeal
commonly lives. Additionally, a dedicated compressor
engages in this mode to help control the aggressive
dynamics generated by speech. This process chain
is perfect for applications where highly amplified,
intelligible speech is the desired output.

• MONITOR Voicing Mode – Monitor mode
was tailored to reduce excess low frequency output
when coupled with the ground, while also reducing
mid-range bite for the artist(s).

This mode should only be engaged when
the speaker is in its monitor orientation
on a stage or floor... if not, the low-end
will sound very lean.

• SUB Voicing Mode – This mode rolls o a little
bit of the low end so you get approximately 3 dB
of extra output from the Thump GO. If you are also
using the Thump GO to high-pass the signal to be sent
to a subwoofer – instead of using the high-pass out
of a subwoofer – then you can use this mode in place
of ‘Music’ mode to benefit from the extra output.

• MEGAPHONE Voicing Mode – This mode
automatically amplifies the overall output.
Megaphone is the voicing mode to select when
“quiet talkers” are giving a speech or presentation.

• WHISPER Voicing Mode – This mode automatically
reduces the overall output. Whisper is the voicing
mode to select when exceptionally “loud talkers”
are essentially shouting a speech or presentation.

20 39 

. 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 . Additionally, the LED will
illuminate green. As if by magic, once the speaking is
completed, the music will return back to its previous
level. True wizards, those engineers... and none of them
have long grey beards, robes and pointy hats.

The audio nerds out there might like
to know that the channel 2 level decreases
by 5 dB when a mic signal is present
in channel  (and when auto-ducking
is engaged, of course).

2. Feedback Eliminator

The multi-band feedback eliminator hunts
down oending 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 oending feedback
frequency. Pretty cool, huh?! The LED will illuminate
green when engaged.

W

0. Outdoor Mode

Regarding outdoor mode... in a sentence, choose
whether you are using Thump GO inside or outside.
The speaker’s voicing is altered to the environment.
That’s all you need to know, but we’re going to give
you more!

When speakers are outside, a combination
of low and high frequencies don’t build up
the way they do inside. Thump GO corrects
for that by boosting the frequency ranges that
become deficient so the speaker sounds the same
outside as when it’s inside. You make the selection,
we’ll do the rest!

The outdoor mode LED will illuminate green when
engaged (outdoors).

When two Thump GO loudspeakers
are linked together in stereo mode,
the feedback eliminator should only
be engaged on the primary Thump GO.

3. Front LED

There is a single horizontal LED bar located near the
bottom-front of each Thump GO. This LED illuminates
green when the front LED switch is engaged.
Additionally, the switch’s LED will illuminate green.
Disengage the switch if you do not want the front panel
LED to illuminate. We like to call this ‘stealth’ mode.

An important note regarding the LED
on the front of your Thump GO.
When Thump GO is powered o

(but still plugged in), the LED functions
as the battery charging level indicator. The front LED
will slow-flash green in increments of 700 ms (700ms
on / 700 ms o). Once fully charged, the LED will stay
illuminated green (no flash).

4. Bluetooth / Pair

While not a “physical” connection, stereo channel 3/4
is considered the Bluetooth channel and its volume
is raised and lowered via the device.

This is how to connect your device to the Thump GO
via Bluetooth! Read on...

Upon powering up the Thump GO, the Bluetooth
function is either:

() In sleep mode. See ‘Pairing and connecting
for the first time’ (below) or...

(2) ...Paired and connected. See ‘Previously paired
and connected devices’ (also below).

Pairing and connecting for the first time:

To enter pairing mode, press and hold the pair switch
down for at least three seconds. The LED will illuminate
and slow flash blue for approximately 30 seconds while
in pairing mode. [The LED will continue to flash until it
has successfully paired and connected].

While Thump GO is in pairing mode, simultaneously
scan for Bluetooth devices on your device. You should
see Thump GO appear in the list of “available devices”.
Select it by tapping it. From there, your Bluetooth
device should indicate that it is successfully
connected. Additionally, the pair button will stop
flashing and remain solid blue. If it does not, start
the pairing process again, and make sure that Thump

Thump GO 8" Portable Battery-Powered Loudspeaker

GO and your device are both in pairing mode at the
same time.

Previously paired and connected devices:

The Bluetooth connection will disconnect if it’s out
of range or if Thump GO is powered o. Previously
paired and connected devices will automatically
reconnect (unless turned o via the Thump Connect 2
App) and the pair button will once again illuminate a
brilliant blue.

To drop the device from being paired with
the Thump GO, press and hold the ‘Bluetooth
Pair’ button down for at least three seconds.

The Bluetooth connection may disconnect
when aected by electrostatic discharge

(ESD) or electrical fast transients (EFT).
If this occurs, manually reconnect the Bluetooth
connection.

If a phone – or two dierent phones – have
been paired via Bluetooth with two Thump GO

loudspeakers, they will not link.
The options are either () one phone connected
via Bluetooth and Thump GO loudspeakers may
be linked or (2) two phones connected via Bluetooth
to two dierent Thump GO loudspeakers and they
may be not be linked.

5. Speaker Link

Two Thump GO loudspeakers may either be linked
together or separate (i.e. not linked). Additionally, there
are options when linked, as they support stereo and
zone (dual mono) linking. However, those features are
only available when connected to the Thump Connect 2
App. It will default to stereo with just the hardware.

To link:

In order to link two Thump GO loudspeakers, press
and hold the ‘Link’ momentary switch / LED down on
the primary Thump GO loudspeaker until the blue LED
illuminates and begins slow-flashing.

Within (approximately) 30 seconds, a quick press
and release of the ‘Link’ button on the secondary
Thump GO allows both units to “see” each other,
handshake and link. The LEDs on both units will stop
flashing and remain solid, indicating great success!.

The Thump GO loudspeakers will continue
to auto-link on every power-up unless this
feature is turned o via the Thump Connect
2 App.

To unlink:

In order to unlink the two Thump GO loudspeakers,
press and hold the ‘Link’ momentary switch / LED down
on one of the Thump GO loudspeakers until the blue
LED turns o. The other Thump Go will automatically
unlink and the LEDs on both units will turn o.

If a phone – or two dierent phones – have
been paired via Bluetooth with two Thump GO

loudspeakers, they will not link. The options
are either () one phone connected via Bluetooth and
Thump GO loudspeakers may be linked or (2) two
phones connected via Bluetooth to two dierent Thump
GO loudspeakers and they may be not be linked.

As mentioned earlier, a Bluetooth connection
may be used simultaneously with the combo

jacks – XLR or /4" – and/or /8" line-level
connection. In other words, if there is a physical
connection to the /8” line input, another physical
connection to the combo jack AND a device
is connected via Bluetooth, none of those inputs
will be interrupted. An easy way to look at it is...
there are extra inputs!

Final Thoughts

6. Overload LED

The Thump GO has a built-in limiter that helps
to prevent the amplifier outputs from clipping
or overdriving the transducers. The limit indicator
illuminates red when the limiter is activated.
It’s okay for it to blink 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’ on page 5 for more
information.

7. Battery LED

This tri-colored LED displays the remaining battery
life. The battery life meter is silkscreened on the rear
panel just below the channel 2 combo jack.
The percentages are also listed below:

• Green = 20% – 00% battery life remaining

• Yellow = 5% – 20% battery life remaining

• Red = less than 5% battery life remaining

• No LED = No battery detected

While the remaining battery life may
be seen on the Thump Connect 2 App,

the most reliable method for knowing
the battery status is still via the battery LED
on the rear panel of Thump GO.

Just a few final thoughts before we dive into a little
more boring “techy”-type stu. For starters, we would
like to remind you once again that Thump GO works
great on its own, but when paired and connected
with a device using the Thump Connect 2 app, your
world of possibilities really opens up!

Factory Reset

Let’s also talk factory resets. Since settings may
be changed via Thump Connect 2, it may be necessary
to reset the Thump GO to its factory settings.

There are two kinds of resets:

• Sof Reset – Just a simple power cycle will reset
all settings that were previously set via the rear
panel and/or app back to their default settings
(except for Bluetooth and linked speakers that
are stored within Thump GO).

• Hard Reset – A hard reset resets the entire
unit to its factory default, including auto-connect
and auto-link. A hard reset may be accomplished
by pressing and holding down the ‘Voicing Modes’
and ‘Outdoor Mode’ buttons simultaneously
for approximately five seconds on boot up.

Please keep in mind that this erases all
settings, including any levels, EQs, etc. that
may have been set. Be sure to power down
any amps and/or powered speakers before

resetting Thump GO.

If you use the factory default key
combination, you are also wiping the
Thump GO’s memory of previously paired

devices. To remedy this, on your phone,
tablet or other Bluetooth device, you will need to ‘forget
device’ in the Bluetooth settings, then re-pair in
order to regain communication and functionality.

Battery Replacement

The Lithium-Ion Battery allows you to use
Thump GO without the need to be plugged
in or wasting money on expensive batteries.

SAFETY FIRST: Before installing and using
this product, please read these instructions
carefully. Failure to follow the precautions

may result in damage, injury, or even death.

. WARNING: The battery (battery or batteries
or battery pack) shall not be exposed to excessive
heat such as sunshine, fire or the like.

2. CAUTION: Danger of explosion if battery
is incorrectly replaced. Replace only with the same
or equivalent type.

Owner’s Manual

3. No open flame sources, such as lighted candles,

should be placed on the apparatus.

WARNING: When installing this product, always
respect the safety standard. Do not install the product
in any way that is not described in these instructions.

BATTERY / COVER REMOVAL INSTRUCTIONS:

Unplug Thump GO and set it upside down on a sof,
flat surface.

Using a flathead or Phillips screwdriver, rotate the
two locking tabs counter-clockwise until they unlock
and “pop” up. Remove the battery compartment cover
and set it aside.

Replace the battery cover and lock it to the Thump
GO by rotating the two locking tabs clockwise until
they lock into place.

When not in use, the spare battery
(purchased separately) may be charged
by plugging the included wall adapter

into the power receptacle of the battery
and the other side into a live AC outlet. The battery
will also charge while inside a plugged-in Thump GO.

Thump Connect 2 App

The Thump Connect 2 App was mentioned at the top

of the hour, but is important enough to mention again.

It is designed to be used in conjunction with Thump
GO. With it, all of the hardware features listed here –
and more! – may be controlled remotely via Bluetooth
connection. The only thing the Thump Connect 2 App
can’t do is turn the Thump GO on and o.

More information about the Thump Connect 2
App may be found by visiting the Thump Connect 2
App Reference Guide.

BATTERY

There are finger grips on each side of the battery,
close to where the “battery” text is located.
Remove the battery from captivity by lifing
it straight up to freedom.

BATTERY INSTALLATION INSTRUCTIONS:

Once the battery cover and battery have been
removed and set aside, it’s time to insert a dierent
one.

NOTE: Do not force the battery into place.
There is only one way it fits and there should
be no resistance during installation.

As seen in the drawing above, a vertical power
connector is located in the upper-lef corner from
where the battery is removed. Line up the power
connector of the battery with the power connector
of Thump GO and press down. Again, this is an easy
process; no force is necessary.

Thump GO 8" Portable Battery-Powered Loudspeaker

Protection Circuitry

Thump GO employs 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 it 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

Let’s take a peek under the hood at the polymer
compression driver. Compared to other available
drivers, these provide a substantially smoother
high-frequency response which results in a studio
monitor level of accuracy and clarity. Furthermore,
these drivers oer an insanely smooth transient
response behavior. Yes, we, too, are fans of our own
products!

Continuing on, 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. Thump GO is 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 Thump GO resumes normal operation.

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

Owner’s Manual

Placement

WARNING: Installation should only be done
by an experienced technician. Improper

installation may result in damage to the
equipment, injury or – while highly unlikely – death.
Make sure that the Thump GO is installed in a stable
and secure way in order to avoid any conditions
that may be dangerous for persons or structures.

Thump GO is 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 T00 is a great tripod option and the SPM400
is a nice choice when using a subwoofer.

Thump GO does not have any fly points
and may NOT be flown. NEVER attempt
to suspend a Thump GO 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).

AC Power

Be sure the Thump GO is plugged into an outlet that
is able to supply the correct voltage. 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 speaker 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 Thump GO. This is very dangerous.

Care and Maintenance

Your Thump GO will provide many years
of reliable service if you follow these guidelines:

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 GO may also be laid out horizontally as
monitors for the band at a 45˚ 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.

As seen above, the Running Man logo
is rotatable for when the loudspeaker
is used as a monitor!

• Avoid exposing it to moisture. If it is set up

outdoors, be sure it is under cover if rain is expected.

• Avoid exposure to extreme cold (below
freezing temperatures). If you must operate
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 cabinet.
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.

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

Thump GO is 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 Thump GO helps
to minimize the problems that typically arise.

Here are some additional placement tips to help
overcome some typical room problems that might arise:

• 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.

• 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

Thump GO 8" Portable Battery-Powered Loudspeaker

to the audience, you increase the overall brightness
and intelligibility of the sound system.

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

Thump GO 8" Portable Battery-Powered Loudspeaker

Appendix A: Service Information

Owner’s Manual

If you think your Thump GO 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 Thump GO.

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 Thump GO 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 Thump GO? 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 Thump GO.
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 Thump GO.

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.

• Are there phasing issues? The signal source should
only be connected to a single input. For example,
do not connect the L/R outputs from a mixer
to the Thump GO channel  and 2 inputs.
Do not use a Y cable to split a phone’s signal,
use both outputs of a stereo synth (which sums
to mono, anyway), etc.

Bluetooth / Linking Issues

• Sometimes a good ‘ol fashioned reset works wonders.
There are two types, sof and hard. See page 3
for more info on resetting Thump GO.

• Try linking two Thump GO loudspeakers together prior
to connecting via Bluetooth.

• Be sure to connect the Bluetooth device to the primary
Thump GO loudspeaker.
