L.U.C.A.S SMART Manual 1.0

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 SMART 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 SMART 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 SMART system should always be swit-

ched 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 SMART. 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 sys-

tem, 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 SMART 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).
