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.
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).

. 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.
The feedback eliminator ONLY aects
channel  (mic and line mode).
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).
