Operating The System; Settings - HK Audio L.U.C.A.S 1000 Mode D'emploi

5 Operating the System

Ensure the Power On switch is set to the Off position
and the power cord is clamped into the tab designed
to hold it in place.
®
Caution: Connecting the L.U.C.A.S
the wrong mains voltage can seriously damage the
power amp!
Turn the Gain knob all the way down (counterclock-
wise as far as the knob will go).
Make sure the system is connected to the satellites
before you power it up, and all connected peripheral
components are switched on first.
Caution: Make sure the Speakon ® connectors are
locked into place by turning them clockwise until
they engage!
Your mixer and all signal sources connected to it,
such as keyboards, instrument amps, effects, and
so forth, should be switched on first.
®
The L.U.C.A.S 1000 system should always be switched
on last, that is, only after you switch on all connected
devices.

6 Settings

Left and Right Gain Knobs
After you power the system up by activating the
On/Off switch (it will light up red when it is set to
On and it is getting mains power), set the Left and
1000 system to Right Gain knobs to the center or 12 o'clock position
(= 0 dBV). This is the preferred level if you have
connected a mixer to your system. If you connect
a CD player or a keyboard directly, the Gain knobs
should be turned clockwise all the way to the far
right to achieve maximum volume.
If you hear distortion or saturated signals, first check
the signal sources and, if possible, reduce the output
signal level there. If the signal that you are routing to
the L.U.C.A.S ®
the source, adjust the power amps by backing off the
Gain knobs (see Tips and Tricks).
Subwoofer Level
When the Gain knob is set to the center position,
the volume of the subwoofer is perfectly balanced
with the levels of the satellites so that the audience
is treated to a homogeneous sound with an even
distribution of bottom end and top end (satellite)
signals. If you want to boost or cut the bass
frequencies, simply turn the Subwoofer Level knob
to the left (down to -12 dB, max) or to the right
(up to +6 dB, max).
Ground Lift Switch
If you encounter low-frequency hum, activate the
Ground Lift switch. If this does not eliminate it,
check all cables connected to the L.U.C.A.S
system and all signals routed to the mixer until you
pinpoint the problem (see Tips and Tricks).
