Thump Series
Frequently Asked Questions
Thump Series
What is the proper method for flying or mounting the
The Thump Series powered speakers do not come with fly
points so these must be pole mounted or stacked from
the floor.
What is the EQ on the speaker used for?
The integrated 3-band EQ on the Thump series
speakers is great for minor adjustments to
accommodate for the particular environment that the
speakers are being used in. If your system is producing
less low end in a particular room than normal, you can
make up for it by turning up the Low EQ a bit.The EQ
can also be used when there are limited EQ options at
the audio source.
Will the Thump Series speakers function as a floor
Absolutely, In fact you will probably have a hard time
finding a floor monitor that sounds as good as this. The
asymmetrical trapezoidal design of the box lets you set
the speaker on its side giving the perfect tilt for a floor
monitor without tipping over and making a hassle.
Can I connect this to the speaker output of an amplifier?
When setting up your Thump speaker, it is very
important that you DO NOT connect it to the output of
an amplifier. The inputs of the Thump series are made
for non-powered outputs such as the main or aux
outputs from a mixer. The outputs of an amp will easily
damage and potentially cause a fire in just about any
powered speaker such as the Thump series.

Frequently Asked Questions
Thump Series
The speaker hums when I connect something to its
The presence of a 60hz hum in the speaker only when a
connection is made to another piece of equipment
suggests the presence of a ground loop. Such a loop is
caused by electrical interaction of the signal grounds on
two pieces of equipment, and is not necessarily an
indication of broken gear. If a balanced connection to the
speaker is being used, the simplest way to correct this
problem is to lift the signal ground on the end of the
connecting cable closest to the signal source. This is not to
be confused with disconnecting the safety ground on the
power plug as this should be avoided at all costs, as it can
present a safety hazard. If an unbalanced connection is
being made to the speaker, a line coupler such as the
Ebtech Hum Eliminator can be used to eliminate the
ground loop.
Is it normal for the speaker to pop when it is
switched on or off?
It is normal for the peaker to emit a slight pop when it is
powered up or down. The pop is caused by electricity
left inside the amplifier circuitry discharging to the
If the volume control is at half, does that mean I
am only getting half power?
The volume control on the Thump series speakers is
actually an input sensitivity control. When set to half or
Unity, it is not adding or subtracting any level from the
source audio signal. Most sources such as a mixer will
have an output that will sound best with this control at
unity. When turning it higher than this, you are not
gaining any more power in the speaker, rather you are
lowering the headroom of the amplifier thus making it
actually work harder than it needs to.
What happens if the Limit light is turning on?
When the Limit light is flashing or on, this means that the
amplifier is being pushed a bit too hard. If you see this
happening, turn down the level control immediately until
the Limit stops lighting.
