9. Voicing Modes
The voicing mode allows you to change the
ThumpXT'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 voicing modes are as follows:
• MUSIC Voicing Mode – This plug-and-play
mode is perfect for listening to mastered music
and is optimized to maintain tonal balance
at peak output volume.
• LIVE Voicing Mode – This mode works well
for singer-songwriters, as it features an upper bass
parametric scoop to reduce unwanted low frequency
color and adds boost to upper mid-range and high
frequencies.
• CLUB 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.
• 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.

10. Outdoor Mode
Regarding outdoor mode... in a sentence, choose
whether you are using ThumpXT 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. ThumpXT 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).

11. 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 1. 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 10 dBu when a mic signal is present
in channel 1 (and when auto-ducking
is engaged, of course).
12. Feedback Eliminator
The multi-band feedback eliminator hunts
down offending 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.
• Off [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 offending feedback
frequency. Pretty cool, huh?! The LED will illuminate
green when engaged.
The feedback eliminator ONLY affects
channel 1 (mic and line mode).
When two ThumpXT loudspeakers
are linked together in stereo mode,
the feedback eliminator should only
be engaged on the primary ThumpXT.
13. Front LED
There is a single horizontal LED located near
the bottom-front of each ThumpXT. 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.
