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.
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:
• 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.
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).
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!
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.
