4. Gain Knobs
The gain knobs adjust the input sensitivity
of the mic/line inputs. This allows signals from
the outside world to be adjusted to run through
each channel at optimal internal operating levels.
It ranges from off (knob fully down) up to max
(knob fully up).
If connecting mixer outputs to loudspeaker
inputs, set the gain knob to 9:00 [“LINE”]
for optimal sound and performance.
5. Mix Out Jack
This is a male XLR-type connector that produces
the mix from the input jacks. Use it to daisy-chain
several Thrash loudspeakers together off the same
signal source(s).
They are wired as follows, according to standards
specified by the AES (Audio Engineering Society):
Balanced XLR Output Connector
Pin 1 – Shield (ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
See page 8 to learn more about daisy-chaining
Thrash loudspeakers.
6. Spigot / Knobs
Thrash loudspeakers can pull double-duty as both
a loudspeaker and a cooler that can hold two different
types of beverages. At the top of each loudspeaker are
two screw-on/off caps. Remove the caps by rotating
them counter-clockwise.
Next, pour a beverage into each open hole; this can
be the same thing in both or something totally different!
Be sure not to overpour. Now just replace the caps
by rotating them clockwise.
The accompanying knobs act as the spigot from off
(knob fully counter-clockwise) to full blast (knob fully
clockwise).
These knobs should always be in the off
position unless pouring a beverage.

Now, if you really poured a beverage (or beverages) in, on
or over the Thrash loudspeaker, your warranty is DEFINITELY voided.
But how cool would it be to go glamping, to your kid’s game, host a BBQ,
etc. with a dual purpose product?

7. Main Volume Knob
The level knob adjusts the overall signal level
at the input to the built-in power amplifiers.
It ranges from Off (– ) to MAX (maximum gain).
• Thrash loudspeakers are designed to operate
with a +4 dBu signal when the main knob is at
the center position.
• Thrash loudspeakers may accept up to a +20 dBu
signal by turning down the main knob accordingly.
• Turning the main knob past center position will
provide enough gain to connect a microphone directly.
Most microphones will want the knob somewhere
around the 9:00 position. For safety, if you’re plugging
in a mic, start with the volume off and gradually
rotate it clockwise until you achieve the desired
volume... and be on the lookout for the dreaded
shriek of the feedback monster.
8. Power / Overload LED
This dual-colored LED will illuminate green
when the loudspeaker is turned on, as a reminder
of how on it really is. If it is not on, then it is off,
and the loudspeaker becomes a rather nice weight
for keeping your morning newspaper from blowing
away in the wind.
If it does not turn on, make sure the power cord
is correctly inserted at both ends, the local AC mains
supply is active and the power switch is on.
Thrash loudspeakers also have a built-in limiter
that helps to prevent the amplifier outputs from clipping
or overdriving the transducers. The LED illuminates
red when the limiter is activated. If this occurs, turn
down the gain knob.
Excessive limiting may lead to overheating,
which in turn trips the thermal protect
circuitry and interrupts the performance.
See ‘Thermal Protection’ on the following page
for more information.
