L.U.C.A.S XT Manual 2.1

4 Operating the System

First, make sure the Power On switch is set to the
Off position.
Caution! Connect the power cable only after you have
made absolutely sure that the local mains voltage
matches the voltage specified on the device. If you
connect the system to the wrong mains voltage, you
can easily damage the electronic components of the
L.U.C.A.S ® XT system.
Gain Line In, Aux In, Mic In
Turn all Gain knobs (Gain Line, Gain Mic and Gain
Aux) all the way down (counterclockwise as far as
they will go).
®
Before you power L.U.C.A.S XT up, make sure that all
connected peripheral components are switched on
first. 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 ® XT system should always be switched
on last. Again, that means after you switch on all
connected devices. After you power the system up by
activating the On/Off switch (it will light up red
when it is set to On and getting mains power),
set the Gain Line knob to the center or 12 o'clock
position (= 0 dBV).
This is the preferred level if you have connected
a mixer to L.U.C.A.S ® XT. If you connect a CD player
or a keyboard directly to the system, turn the Gain
Line knob clockwise all the way to the far right to
achieve maximum volume.
Note: Many DJ mixing desks are equipped with RCA-
format outputs only. If you want to employ this type
of mixer, use either an RCA/XLR adapter (or RCA/1/4"
jack adapter) and plug it into the Line In port,
or connect the mixer to Aux In using a standard
RCA connector-equipped cord.
If you want to plug a CD player directly into the system,
use Aux In to do this. Depending on signal level, you
can turn the Gain Aux knob all the way to the right in
order to achieve maximum volume.

5 Settings

Gain Mic Knob
Use this knob to adjust microphone level.
Note: You can adjust the microphone and line inputs
separately and mix them as desired. In the event of
audible distortion or saturated signals, back off the
Gain Mic knob.
Gain Line Knob
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 ® XT system cannot be adjusted at the
source, adjust the power amp by backing off the
Gain Line knob.
Gain Aux Knob
Use this knob to adjust the level of the Aux In channel.
Note: You can adjust Aux In and Line In separately
and mix them as desired. In the event of audible
distortion or saturated signals, back off the
Gain Aux knob.
Mode
If you have just a mono signal available, patch it to
the left input of the Line In or Aux In circuits. Set
the Mode switch to Mono. This way the system can
output the monaural input signal on both left and
right sides.
Balance
Use the Balance knob to adjust the relative levels of
the left and right channels. The two sides' volume
levels are equal when the knob is set to the center
position.
Subwoofer Level
When this 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 frequen-
cies, simply turn the Subwoofer Level knob to the left
(down to -12 dB) or right (up to +6 dB).
