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 0 dBu
when a mic signal is present in channel  (and when auto-ducking is engaged, of course).
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 ThumpXT loudspeakers are linked together in stereo mode, the feedback eliminator
should only be engaged on the primary ThumpXT.
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.
