U.c.a.s Smart Accessories; Tips And Tricks - HK Audio L.U.C.A.S SMART Mode D'emploi

Ground Lift Switch
If you encounter low frequency hum, try activating
the Ground Lift switch, which severs the chassis
earth circuit. If this doesn't eliminate the problem,
check all cables connected to the L.U.C.A.S SMART
system and all signals routed to the mixer until you
pinpoint the problem.
Caution: Never tape over the plug's ground terminal
– this endangers lives!

7 Tips and Tricks

1 Don't 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.
2 L.U.C.A.S SMART delivers optimum sound when
you provide it with optimum input signals! Noise
such as hum is generally caused by defective
cables, the wrong type of cables, or unbalanced
signals routed into the mixing console. Check all
signal and mains cables.
3 Prevent distortion! Not only is it unpleasant to
the ears of your audience, it can also endanger
your equipment. Make sure all components
that are connected directly and indirectly to the
L.U.C.A.S SMART system have sufficient power
ratings, and that they don't distort from running
at their respective limits. Provide an undistorted
signal to the system. If you send a distorted signal,
backing off the Gain knob won't help clean it up.
Keep it clean!
4 Avoid ground loops! Even if the signal-carrying
circuit is balanced, redundant ground circuits in
a single audio system may generate undesirable
humming. For example, you may encounter a
ground loop when the mixer is grounded via a
mains cord that isn't connected to the same mains
circuit as the L.U.C.A.S SMART system. To prevent
this problem, always be sure to connect L.U.C.A.S
SMART and the mixing console to the same electri-
cal circuit. (Same phase!) If your equipment hums
despite this precaution, the Ground Lift switch can
be a great help.
