These fans (on the side and back of the housing)
keep the power amp modules cool. Always keep the
fan and ventilation vents free of dirt and debris, and
ensure they remain unobstructed so air can circulate
freely.

left and right L.U.C.A.S PERFORMER satellite out-
puts using speaker cables equipped with Speakon
connectors. Note: Be sure to twist the Speakon

catch towards the cord.

4 Tips and Tricks

• Do not expose electronic circuitry to moisture!
When you set the system up outdoors, be sure to
protect it against rain. Keep soft drinks, beer or any
other liquids well away from the cabinets to protect
their electronic components from short circuits.
• To ensure proper ventilation, make sure the sub-
woofer is placed a sufficient distance away from
walls and isn't covered by curtains and the like.
This is vital to keep the power amps cool.
• Ensure that the vents on the subwoofer's side
panels are free of dirt and that the fan blades can
rotate freely. Otherwise, electronic components
may overheat and suffer damage.
• L.U.C.A.S PERFORMER takes care of delivering
optimum sound—so provide it with optimum
input signals! Noise such as hum is generally
caused by defective cables, the wrong type of
cables, or unbalanced signals being fed to the
mixing console. Check all audio cables and mains
cables.
• Avoid distortion! Not only is it unpleasant to your
audience's ears, it also endangers your equipment.
Make sure all components that are connected
directly and indirectly to L.U.C.A.S PERFORMER
have sufficient power ratings, and that they are not
distorting from being driven at their respective
limits. Provide a clean, undistorted signal to the
® inputs to the system that won't require backing off the Gain
knob to clean it up.

® • Avoid ground loops! If, for example, you connect
the mixer to one mains circuit/wall outlet, and
L.U.C.A.S PERFORMER to another, you may
encounter a ground loop. To prevent this problem,
always connect the L.U.C.A.S PERFORMER system
and the mixing console to the same electrical
circuit (same phase!). If your equipment hums
despite this precaution, the Ground Lift switch can
be a great help.
CAUTION: Never tape over the plug's ground
terminal – this endangers lives!
