ThumpXT Series Loudspeakers: Rear Panel Features
. Power Connection
This is a standard 3-prong IEC power connector.
Connect the detachable power cord (included in
the packaging with the loudspeaker) 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 loudspeaker. Press the lef side of this
rocker switch inwards to turn o the loudspeaker.
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.
3. XLR and /4" Combo Input Jacks
Input channels  and 2 may accept a balanced
mic signal using an XLR connector. 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)
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 (–)
To connect unbalanced lines to these inputs,
use a /4" mono (TS) phone plug, wired as follows:
/4" TS Unbalanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
NEVER connect the output of an amplifier
directly to a ThumpXT input jack. This could
damage the input circuitry!
