• Gli impianti elettrici nei locali prescelti per l'uso dell'apparecchio rispondono
alle normative stabilite dall'ANSI.

• L'apparecchio viene utilizzato come indicato nel libretto delle istruzioni per l'uso.

Avvertimenti:

• In caso di apertura di parti di rivestimento o rimozione di parti dell'involucro,
a meno che non si tratti di pezzi rimovibili semplicemente a mano, possono
venire alla luce parti dell'apparecchio conduttrici di tensione.

• Se l'apertura dell'apparecchio dovesse risultare necessaria è indispensabile
staccare precedentemente quest'ultimo da tutte le fonti di tensione. Rispettare
tale misura di prevenzione anche prima di un allineamento, di operazioni di
manutenzione, della messa in esercizio o della sostituzione di componenti
all'interno dell'apparecchio.

• Allineamento, operazioni di manutenzione o eventuali riparazioni dell'apparec­chio in presenza di tensione vanno eseguite esclusivamente da personale
specializzato ed autorizzato, in grado di eseguire tali operazioni evitandone
i rischi connessi.

• Le uscite degli altoparlanti contrassegnate dai caratteri IEC 417/5036 (vedi
illustrazione 1 a fondo pag.) possono essere conduttrici di tensione pericolosa
con cui evitare il contatto. Per questo motivo, prima di accendere l'apparec­chio, collegare quest'ultimo agli altoparlanti servendosi esclusivamente del
cavetto d'allacciamento indicato dal produttore.

•Tutte le spine e i cavi di collegamento devono essere avvitati o fissati all'involu­cro dell'apparecchio per quanto possibile.

• Utilizzare esclusivamente fusibili del tipo IEC 127 con la indicata corrente no­minale.

• L'utilizzo di fusibili di sicurezza non integri e la messa in corto circuito del
sostegno di metallo sono proibite.

• Non interrompere mai il collegamento con il circuito di protezione.

• Superfici contrassegnate dalla parola "HOT" (vedi illustrazione 2 a fondo pag.),
cosi come griglie di aerazione, dispositivi di raffreddamento e i loro rivestimen­ti di protezione, oppure valvole e i relativi rivestimenti protettivi possono surri­scaldarsi notevolmente durante l'uso e per questo motivo non vanno toccate.

• L'ascolto di suoni ad alto volume può provocare danni permanenti all'udito.
Evitate perciò la diretta vicinanza con altoparlanti ad alta emissione di suono
e utilizzate cuffie protettive in caso ciò non sia possibile.

Alimentazione:

• L'apparecchio è concepito per il funzionamento continuo.

• La tensione di esercizio deve corrispondere alla tensione di rete a cui ci si allaccia.

• L'allacciamento alla rete elettrica avviene tramite alimentatore o cavetto d'ali­mentazione consegnato insieme all'apparecchio.

• Alimentatore: un cavo di connessione danneggiato non può essere sostituito.
L'alimentatore non può più essere utilizzato.

•Evitate un allacciamento alla rete di corrente utilizzando cassette di distribu­zione sovraccariche.

• La spina di corrente deve essere situata nelle vicinanze dell'apparecchio e
facilmente raggiungibile in qualsiasi momento.

Locali di collocamento:

• Opportuno collocare l'apparecchio su una superficie pulita e orizzontale.

• Non sottoporre l'apparecchio in funzione a scosse e vibrazioni.

• Proteggere l'apparecchio per quanto possibile da umidità e polvere.

• Provvedere ad una buone aerazione dell'apparecchio.

•Eventuali aperture previste per la ventilazione dell'apparecchio non vanno ne
bloccate, ne mai coperte. L'apparecchio va collocato ad almeno 20 cm di
distanza dalle pareti circostanti e può essere inserito tra altre componenti di un
impianto solo in caso di sufficiente ventilazione e qualora le direttive di
montaggio del produttore vengano rispettate.

•Evitare di esporre l'apparecchio ai raggi del sole e di collocarlo direttamente
nelle vicinanze di fonti di calore come caloriferi, stufette, ecc.

• Se l'apparecchio viene trasportato rapidamente da un locale freddo ad uno
riscaldato può succedere che al suo interno si crei della condensa. Ciò va
tenuto in considerazione soprattutto in caso di apparecchi a valvole. Attendere
che l'apparecchio abbia assunto la temperatura ambiente prima di accenderlo.

• Accessori: non collocare l'apparecchio su carrelli, supporti, treppiedi, superfici
o tavoli instabili. Se l'apparecchio dovesse cadere a terra potrebbe causare
danni a terzi o danneggiarsi irreparabilmente. Utilizzate per il collocamento
dell'apparecchio supporti, treppiedi e superfici che siano consigliate dal
produttore o direttamente comprese nell'offerta di vendita. Per il collocamento
dell'apparecchio attenetevi strettamente alle istruzioni del produttore, utiliz­zando esclusivamente accessori da esso consigliati. L'apparecchio in combina­zione ad un supporto va spostato con molta attenzione. Movimenti bruschi o il
collocamento su pavimenti non piani possono provocare la caduta dell'appa­recchio e del suo supporto.

• Accessori supplementari: non utilizzate mai accessori supplementari che non
siano consigliati dal produttore, potendo essere ciò causa di incidenti.

• Per proteggere l'apparecchio in caso di temporali o nel caso questo non venisse
utilizzato per diverso tempo si consiglia di staccarne la spina di corrente.
In questo modo si evitano danni all'apparecchio dovuti a colpi di fulmine o ad
improvvisi aumenti di tensione nel circuito di corrente alternata.

Digital Amping

Enhanced Efficiency and Dynamic Response

With an efficiency rating topping the 90% mark,
digital power amps are smaller, lighter, and more
compact than comparable conventional amps.
The reduced thermal load on components clearly
enhances reliability. The slew rate is far faster and
the damping factor is higher, resulting in audibly
more responsive and accurate performance.

• Outperforms analog power amps in efficiency for
greater reliability and lower current consumption

• Faster signal transmission for enhanced dynamic
response

OFR™

Optimized Frequency Response Technology

HK AUDIO

®

’s unique OFR™ technology deliver
commanding yet well-balanced sound at every level.
It corrects for non-linear frequency response in the
speaker components at the same time as it compen­sates for the way human hearing works at varying
levels.

• Fine-tuned to each system

• Rectifies non-linear frequency response

• Adapts the system to different volumes

• Powerful, balanced sound in every situation

MultiBand Limiting

Specialized limiting for each frequency range

Several limiters, each specializing in its own
frequency range, work side by side to keep the entire
system under control. This ensures even dynamic
response and punchy projection for a highly musical
sound across the entire frequency spectrum.

• Tighter low-end punch, snappier kick

• Clean, emphatic mids for smooth, rich vocals

• Transparent, glossy highs with extra headroom

• Speaker overload protection

Subsonic Filter

Preventing Low Frequency Interference

The integrated subsonic filter eliminates accidental
and unintentional signals such as footfalls, wind, or
the sound of a hand accidentally brushing a micro­phone. It cuts these frequencies drastically, freeing
energy to render bass impulses better. Goodbye
squashed dynamics and artificial sound, hello
authenticity and natural sounding low/mid
frequencies.

• Increases power and volume in the useful
frequency range

• Protects power amps and speakers from harmful
ultra-low frequencies

DuoTilt™ and MicroTilt™

Making the Most of Sonic Energy

The new DuoTilt™ and MicroTilt™ speaker stand
mounting collars allow sound energy to be utilized
far more efficiently. The DuoTilt™ offers downward
angles of 7.5° and 15°, and MicroTilt™ 10°, to better
aim the mid/high-range cabinets directly at the
audience. Troublesome ceiling reflections are
minimized; the soundscape is clearer, tighter, and
more focused.

• Tilts at angles designed for the best possible
alignment of the enclosure to the audience

• Minimizes ceiling reflections, maximizes energy
efficiency

XT’s Control Features

1 Gain Mic

Twist this knob to adjust the microphone level.

Note: You can adjust the microphone and line or
auxiliary inputs separately and mix them as desired.

2 Gain Line

This knob adjusts power amp gain to match input
signal levels. In the event that distortion becomes
audible, the incoming signal level is too high. Simply
back off this knob.

3 Gain Aux

This knob adjusts power amp gain to match input
signal levels. In the event that distortion becomes
audible, the incoming signal level is too high. Simply
back off this knob.

4 Limiter Status LEDs

These dual-color LEDs indicate the operating status
of the multi-band limiter. Green = incoming signal,
limiters inactive; yellow = limiter occasionally activated;
red = limiters operating continuously.

5 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. When you do this, the system
outputs the monaural input signal on both sides (the
left and right).

6 Balance

Use this knob to adjust the relative levels of the left
and right channels.

7 Subwoofer Level

Use this knob to adjust the relative volume of the
subwoofer.

8 Power On LED

This LED lights up when the system is plugged into a
mains power supply and the Power switch (see rear
panel) is set to On.

9 Ground

Ground lift switch for separating the signal and
chassis ground when you encounter problems with
humming noises. The ground circuit is severed when
you press the button in.

Caution: Never tape over the plug’s ground terminal
– this endangers lives!

10 Mic In

You may plug a microphone directly into this electro­nically balanced XLR input. (pin 1= ground, 2= +, 3= -).

11 Line In Left/Right

This electronically balanced XLR input is designed
to take mixer signals (pin 1= ground, 2= +, 3= -).
You can also use cables equipped with 1/4" TRS (stereo­style) plugs (tip = +, ring = -, shield = ground).

12 Aux In

RCA connector designed to take external signal
sources such as (DJ) mixing consoles and CD players.

13 Mix Out

Master output for patching Line, Aux In and Mic In
signals through to other devices such as tape decks
and MD recorders or another L.U.C.A.S

®

XT system.

14 To Satellite Left/Right

Connect these Speakon®outputs to L.U.C.A.S®XT’s
satellite speakers.

15 Fuse

Mains fuse. In the event of a malfunction, this
fuse will blow, severing the connection between
L.U.C.A.S®XT and the mains power supply in order
to protect the system from harm. Replace only with
another fuse of the same type and rating as specified.

2 Setting Up and Connecting
L.U.C.A.S

®

XT

Line In

Connect cables carrying signals from your mixer
(master left/right, line out, or a similar circuit) to the
balanced Input sockets using a cord equipped with
standard XLR microphone connectors or 1/4" plugs.
Make sure the XLR connectors have the following pin
assignments: 1= ground, 2= +, 3= -. You can also use
cables equipped with 1/4" TRS (stereo-style) plugs
(tip = +, ring = -, shield = ground).

Aux In

Connect cables carrying signals from your DJ mixer,
CD player or tape deck (CD out, tape out, or similar
output) to Aux In using a cable equipped with RCA
connectors.

Mic In

If you want to connect a microphone directly to
L.U.C.A.S

®

XT without going into a mixer first, plug it
into the balanced Mic In socket. Use a standard XLR
microphone cable for this. Make sure the XLR con­nectors are wired with pin 2 hot (pin assignments:
1 = ground, 2 = +, 3 = -).

Satellite Left/ Right

Connect the L.U.C.A.S®XT system’s satellite speakers
to the Satellite Left and Satellite Right outputs. Use
Speakon®loudspeaker cables with wire cross-sections
of at least 2 x 1.5 mm2to do this.

Caution: The Satellite Left and Satellite Right outputs
are designed for a nominal impedance of four ohms.
Under no circumstances may the impedance fall
below this value, otherwise the power amp may

suffer serious damage! Use L.U.C.A.S

®

XT satellite

loudspeakers only!

Note: This system’s components were matched
and tuned for superior audio performance in the
configuration described herein. Do not set up or
use this system in any other configuration. If you use
satellites other than those that ship with the system,
this could degrade the system’s sound or even damage
the power amp.

An electrical connection between the cord and input
jack is not established until the Speakon®connector
locks into place. Turn the Speakon connector
clockwise until it engages.

3 Mounting the Satellites
on Speaker Stands

The newly developed, integrated MicroTilt™ pole
mount enables far more efficient use of sound energy.
Offering a 10° angle of tilt, it lets you line up cabinets
so that they face the audience rather than towards
walls and ceilings. Troublesome ceiling reflections
are minimized, and you end up with a focused sound
that is clear and punchy. Cabinets are stabilized
at their center of gravity - no wobbling, tilting, or
unintentional turning. What’s more, the HK AUDIO

®

MicroTilt™ collar can accept microphone stands.
The maximum attainable height with microphone
stands is 165 to 170 cm (about 5 1/2 feet), which is
often sufficient for smaller events or presentations
at which the audience is seated.

The HK AUDIO®L.U.C.A.S®XT Add-On Package is
highly recommended for musical performances or
presentations requiring coverage of greater areas
and distance (10 to 15 meters / 30 to 50 feet). This
kit consists of two stands (extendable to a height of
205 cm / 6’ 8"), a practical gig bag for easy transport
and two loudspeaker cables for connecting the
satellites to the subwoofer.

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 RCA­format 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 frequen­cies, simply turn the Subwoofer Level knob to the left
(down to -12 dB) or right (up to +6 dB).

English

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®XT 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®XT 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®XT 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

®

XT system. To prevent this
problem, always be sure to connect L.U.C.A.S®XT
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!

8 Troubleshooting

The Power On LED and the mains switch do not
light up red after you switch the system on.

• Check if the power cord is plugged into the
Mains Input.

• Check if the mains power supply is actually
providing current.

• Check if L.U.C.A.S®XT’s fuse is defective. Replace
only with another fuse of the same type and rating
as specified.

The Power On LED and the Power switch light up
red, but no sound is coming from the cabinets.

• Check the cables that you connected to the Line In,
Mic In and Aux ports.

• Check if the signal sources (mixer, keyboard,
CD player) are on.

• Are the Gain knobs turned up?

• Check the loudspeaker cables for damage.

• Check if the Speakon®connectors plugged into the
Satellite Left and Satellite Right sockets are engaged
all the way (rotated fully to the right). Only then
will an electrical connection be established.

The subwoofer’s bass response sounds thin or weak.

• Check the setting of the Subwoofer Level knob.
Adjust the volume of the subwoofer using the
Subwoofer Level knob until you get the kind of
bottom end you want to hear.

The signal sounds distorted.

• Check the LED displays on your mixer. They should
not be constantly in the red. If necessary, back off
the volume at the mixer.

• If the LED displays on your mixer are in the green,
turn down the L.U.C.A.S®XT’s Gain knob (Line In
or Aux In).

• Observe the LEDs of the Limiter Status displays on
L.U.C.A.S®XT’s control panel. If the yellow LED lights
up continuously, the integrated protective functions
are working at full capacity. In this instance, do not
turn the volume level up any higher.

Annoying hum

• Check the cables that you are using to connect the
signal source to L.U.C.A.S®XT. Replace damaged cables.

• If you cannot pinpoint the cause of the hum, press
the Ground Lift switch. This should remedy the
problem in most cases.
