dalla HK AUDIO® stessa o da personale da essa autorizzato.

• 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 distribu zione
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.

• L’apparecchio deve essere posizionato sempre in modo da assicurare il libero accesso
all’interruttore di alimentazione.

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

• Non collocare l'apparecchio vicino ad acqua, vasche da bagno, lavandini, lavelli da
cucina, locali umidi o piscine. Non appoggiare recipienti contenenti liquidi - vasi,
bicchieri, bottiglie, ecc. - sull'apparecchio.

• 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.

instalación se deben seguir las indicaciones del productor así como utilizar los acces­orios recomendados por el mismo para colocarlo encima. El conjunto del aparato con
el pedestal se debe mover con mucho cuidado. Un paro brusco, la aplicación de una
fuerza desmesurada o un suelo irregular puede ocasionar la caida de todo el conjunto.

• Piezas adicionales: no utilice nunca piezas adicionales que no estén recomendadas
por el productor, ya que se podrían provocar accidentes.

• Para protejer el aparato de una tormenta o si no se supervisa ni utiliza durante algún
tiempo, se debería desconectar la clavija de la red. Así se evitan daños en el aparato a
causa de un rayo y golpes de tensión en la red de corriente alterna.

DDO™ Controller technology

The DDO™ controller compensates for the varying
response of PA components such as low-frequency,
midrange and high-frequency speakers, power amps,
crossovers and so forth to forge a homogenous
system with uniform dynamics and a sonic image
with sharply defined contours.

Digital amping for enhanced efficiency and dynamic
response

With an efficiency rating topping the 90% mark,
Class-D digital power amps are substantially smaller,
lighter, and more compact than conventional amps.
The reduced thermal load on components enhances
reliability, while the far faster slew rate and higher
damping factor audibly enhances the speed and
precision of the system’s dynamic response.

Multi-band limiting and companding

Several matched limiters and companders are fine­tuned and optimised to process different frequency
ranges. This speaker-independent approach to signal
processing results in natural-sounding dynamic
response across the entire frequency spectrum and
produces a powerful yet finely balanced sonic image.

Making the most of sonic energy with MonoTilt™

The newly developed, integrated MonoTilt ™ pole
mount allows sound energy to be utilized with
great efficiency. Troublesome ceiling reflections are
minimized; the sound is clearer, tighter, and more
focused.
Beyond that, the cabinet is stabilized at its center
of gravity - no wobbling, tilting, or unintentional
turning.

Easy setup and handling for less pre-gig stress

Like all HK AUDIO active rigs, L.U.C.A.S IMPACT
was conceived as a cohesive system comprising
painstakingly matched components. This rig was
engineered for easy portability and swift set-up.
Operation is simple, with no complicated tweaking
required.

• Genuine system design: All components are
precision-matched.

• Swift set-up & easy operation to save time

• Less stress = more fun + better music

Subsonic filter

The integrated subsonic filter cuts unwanted ultra­low frequencies. Infra sub-bass signals resulting
from stage rumble, wind or similar sources place
heavy demands on the power amp to render
frequencies so low that they exceed the useful range
of the speaker cabinet. The subsonic filter protects
the amp from these frequencies, thereby increasing
the entire system’s output power.

• Protects both power amps and speakers from
harmful ultralow frequencies.

• Enables cleaner and tighter bass response and
higher output levels.

Components

Subwoofer

The L.U.C.A.S IMPACT subwoofer’s housing is split
into two chambers. The front chamber serves as
the speaker cabinet for the 15" direct-loaded loud­speaker, which has a power-handling capacity of
700-W and a nominal impedance of 8 ohms.
The active electronic circuitry, the power unit,
DDO™ digital controllers and Class D power amps
are housed in a separate compartment at the rear of
the cabinet.

Satellites

Satellites are loaded with a 8" HK AUDIO Custom
speaker and a 1" compression driver with a 60° x 40°
CD horn. They are rated for 250 W RMS power-hand­ling capacity and a nominal impedance of 8 ohms.

The newly developed, integrated MonoTilt ™ pole
mount allows sound energy to be utilized with
great efficiency. Troublesome ceiling reflections are
minimized; the sound is clearer, tighter, and more
focused.
Beyond that, the cabinet is stabilized at its center
of gravity - no wobbling, tilting, or unintentional
turning.

2 Transport

To transport the system, simply set the subwoofer
on its casters and place the satellites onto the
subwoofer with the foam-rubber grille side facing
down. Secure the satellites, for example, using a
locking strap. Use original HK Audio L.U.C.A.S
IMPACT protective covers to gear up your personal
system for the rigors of the road. Amply padded and
protected against moisture, your L.U.C.A.S IMPACT
is sure to deliver satisfying performance for a long
time to come.

More about limiters

Limiters are designed to protect power amps and
the speakers connected to them from damage. The
functionality and response of a limiter is determi­ned by parameters called attack time, threshold
and release time. Adjusting these parameters
incorrectly can degrade the sound and bring about
dynamic distortion. At peak volume levels, for ex­ample, vocals may fail to cut through the mix and
instruments that are played percussively may lose
their punch and dynamics.

HK AUDIO limiting technologies are more than
merely technical tools serving to protect compo­nents. We put a premium on authenticity, that is,
retaining an audio event’s true dynamics. This
explains why our limiters are first and foremost
designed to optimise the sound, though they of
course also protect the system.

Features

L.U.C.A.S IMPACT Subwoofer

1 Limiter LEDs

Much like rev counters, these LEDs indicate the
active system’s operating status. For more info, read
the sidebar “More about Limiter LEDs.”

2 Gain

Operation: Turn the Gain knob all the way down
(counterclockwise) before switching the system on.

Ensure the system is connected to the satellites
and all other connected components are on before
powering it up. Be sure to switch on the connected
mixer as well as all signal sources connected to it,
for example, keyboards, amps, effects, and so forth.

After you power the system up, set the Gain knob to
the 0 dBV or 12 o’clock setting. This is the preferred
level if you have connected a mixer. (Note: If you
connect a CD player or a keyboard directly to the
system, you may not be able to achieve peak volume
at this setting. If this is the case, twist the Gain knob
to the far right.)

If you hear distortion or a saturated signal, first
check the signal sources and, if possible, reduce
the output signal level there. If you are unable to
turn down the level of the signal sent to L.U.C.A.S
IMPACT at the signal source, adjust the input
sensitivity using the Gain knobs. (see also Tips and
Tricks—section 4).

3 Balance

Operation: Twist the Balance knob to the left or right
to adjust the relative balance of levels between the
left and right channels.

4 Display

Display: The numeric display indicates the currently
selected system configuration (0 to 5).

0 Mute - System switched to silent mode.
Zero sound signal reproduction.

1 Speech - Set-up for speech.
This mode places emphasis upon vocal and spoken
language reproduction. To minimize subsonic inter­ference and background noise over the microphone,
the subwoofer level is reduced.

2 Live 1 - Set-up 1 for use during live performance.
The Live 1 setup enables punchy, dynamic bass
with rapid transient response. Vocals are likewise
predominant in this sound profile.

3 Live 2 - Set-up 2 for use during live performance.
The Live 2 set-up delivers softer and deeper bass
reproduction at a slightly lower level. The vocals are
slightly less in the foreground when compared to the
Live 1 set-up.

4 DJ 1 - Set-up 1 for reproduction of music from
CDs.
The DJ 1 set-up provides an ideal setting for CD
reproduction, with strong deep bass, discreet
midrange and accentuated highs.

5 DJ 2 - Set-up 2 for reproduction of CD/ MP3
music.
Like DJ1 above, the DJ 2 set-up can also be used for
CD reproduction, but is optimised for MP3-encoded
sources to revitalize the sound with more dynamic
bass, smoother highs and a more natural, less
compressed sound.

Note: A flashing display indicates that the controller
has muted the input. This mute function is triggered
via the input signal level. The system is muted when
its level falls below the threshold value. The system
is enabled as soon as the input signal level rises
above the threshold value.

5 Up/Down Buttons

Press these buttons to change system configurati­ons. Operation: Simultaneously press and hold the
Up and Down buttons for about 1-2 seconds. Once
the letter U (Unlock) appears briefly in the display
you can use the Up and Down buttons to select the
desired setup. The buttons lock again automatically
after a moment, at which time the letter L (Lock)
appears briefly in the display.

6 Subwoofer Level

Handling: When this knob is set to the 12 o’clock
position, the subwoofer’s and the satellite’s
respective volumes are matched, ensuring the
proper balance between the subwoofer’s bass output
and the stallites’ mid/high-range output. If desired,
you can twist the Subwoofer Level knob to the left,
i.e. counterclockwise, to cut the subwoofer’s level by
as much as -12 dB and to the right to boost it by as
much as 6 dB.

7 Ground

Ground lift button for separating the signal and
chassis ground in the event of hum. To rid the
system of low-frequency hum, press the Ground
switch in. If this doesn’t solve the problem, check
all power and audio cables connected to L.U.C.A.S
IMPACT for damage, as well as all cables routing si­gnals to the mixing console (see also Tips and Tricks
in Section 4).

8 Input Left and Input Right (Combination XLR/1/4"
jacks)
L.U.C.A.S IMPACT is equipped with separate left and
right channel inputs for connecting to a mixer.

Connections: Connect the audio cables that route
the signal coming from your mixer (master left/
right, line out, or a similar circuit) to these balanced
inputs using microphone cables equipped with XLR
connectors. The XLR connectors’ pin assign ments

15

must be as follows:
1= ground, 2= +, 3= -.

You can also use a 1/4" Tip-Ring-Sleeve plug to route
signals via balanced circuits. Unbalanced signals can
be patched in via a mono plug.

9 Through Left, Through Right

Connections: Parallel outputs for routing the line
signal (left or right) to other systems, outboard com­ponents, monitor power amps, etc., via XLR cables

10 Sensitivity

This switch boosts input sensitivity. Setting it to

-6 dB rather than the standard +4 dB setting boosts
the input level 10 dB. For the widest dynamic range
in live applications, we recommend setting the
switch to +4 dB.
Recommendation: Using a professionell mixer, the
input sensitivity should be set to +4 dB. This lets
you take advantage of the system’s full dynamic
range and helps to avoid system overloads.
Using a signal with a lower output level the input
sensitivity should be set to -6 dB.

Note: Once you have engaged the Power switch,
it will take several seconds for the display to light
up and the system to be ready for operation. This
is standard procedure and does not indicate a mal­function.

The active L.U.C.A.S IMPACT system should always
be switched on last after you power up all equip­ment connected to it, and should be switched off
first before you switch off all the other equipment
connected to it.

13 Mains Input

Connections: Use the factory-included mains cable
(power cord) to connect from this socket to a wall
receptacle. Caution! Make sure the local mains
voltage matches the voltage specified on the de­vice. Connecting the system to the wrong mains
voltage may destroy the L.U.C.A.S IMPACT system’s
electronic components.

14 Mains Cable Tab

Clamp the power cable into the tab to prevent it
from being pulled out inadvertently.

15 Fans

These fans (on the side and back of the housing)
keep the power amp modules cool. Always keep the
fan and ventilation vents free of dirt and debris, and
ensure they remain unobstructed so air can circulate
freely.

L.U.C.A.S IMPACT Satellite

11 Speaker Out (To Satellite Left und Right)

Connections: Connect these Speakon outputs to
the left and right L.U.C.A.S IMPACT satellites using
speaker cables equipped with Speakon connectors.
Note: Be sure to rotate the Speakon connectors
clockwise until they lock in place!

12 Power Switch

Operation: On/off switch for the active system.
The display on the system controller glows orange to
indicate that the system is on.

Input

Connections: Connect the Speakon inputs to the left
and right L.U.C.A.S IMPACT satellite outputs using
speaker cables equipped with Speakon connectors.
Note: Be sure to twist the Speakon connectors
clockwise until they lock in place! You must first
disengage the safety catch before you can unplug
the connector. To do this, pull the bayonet catch
towards the cord.

4 Tips and Tricks

• Do not 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.

• To ensure proper ventilation, make sure the sub­woofer is placed a sufficient distance away from
walls and isn’t covered by curtains and the like.
This is vital to keep the power amps cool.

• Ensure that the vents on the subwoofer’s side
panels are free of dirt and that the fan blades can
rotate freely. Otherwise, electronic components
may overheat and suffer damage.

• L.U.C.A.S IMPACT takes care of delivering
optimum sound—so provide it with optimum in­put signals! Noise such as hum is generally caused
by defective cables, the wrong type of cables, or
unbalanced signals being fed to the mixing conso­le. Check all audio cables and mains cables.

• Avoid distortion! Not only is it unpleasant to your
audience’s ears, it also endangers your equipment.
Make sure all components that are connected
directly and indirectly to L.U.C.A.S IMPACT have
sufficient power ratings, and that they are not
distorting from being driven at their respective
limits. Provide a clean, undistorted signal to the
system that won’t require backing off the Gain
knob to clean it up.

consisting of two aluminum cabinet tripods, one gig
bag, and two speaker cables.

HK AUDIO Protective Covers for L.U.C.A.S IMPACT

This set comprises one cover for the subwoofer
and two covers for the satellites. Tear-resistant and
water-repellant, these rugged covers are thickly
padded to afford lasting protection for the L.U.C.A.S
IMPACT system during transport.

To learn more about Original HK Audio Accessories,
talk to your HK AUDIO dealer or visit www.hkaudio.
com.

• Avoid ground loops! If, for example, you connect
the mixer to one mains circuit/wall outlet, and
L.U.C.A.S IMPACT to another, you may encounter
a ground loop. To prevent this problem, always
connect the L.U.C.A.S IMPACT system 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!

6 Troubleshooting

The display does not light up when switched on.

1 Check if the power cable is plugged into the Mains

Input.

2 Check if the mains power supply is providing

current.

The display lights up, but there is no sound coming
from the cabinets.

1 Check the cables connected to the Left and Right

inputs.

2 Check if the signal sources (mixer, keyboard, CD

player) are on.
3 Is the Gain knob turned up?
4 Check the speaker cables for damage.
5 Check if the Speakon“ connectors are fully enga-

ged in their sockets (rotated to the right). They
must be locked in place to establish an electrical
connection.

The subwoofer’s low frequency output is too soft.

1 Check the setting of the Subwoofer Level knob.

Adjust this knob to set the volume of the sub­woofer to the desired level.

Level problems

1 Check the Sensitivity switch’s setting. When it is

set to +4 dB, and you feed in a signal with a level
of +4 dB (for example, from a connected mixing
console), the system delivers 0dB output level.
This lets you take advantage of the system’s full
dynamic range. When it is set to -6 dB, and you
feed in a signal with a level of -6 dB, the sys­tem delivers 0 dB output level. This boosts the
system’s output level by 10 dB, but reduces the
dynamic range at higher volumes. This is why
we recommend running the rig at +4 dB in live
situations.

This is to certify that

Sound seems distorted.

1 Check the LED displays on your mixer. They should

not be constantly in the red. If necessary, reduce
the volume at the mixer.

2 If the LED displays on your mixer are in the green,

turn back L.U.C.A.S IMPACT’s Gain knob.
3 Watch the LEDs of the Limit Left, Limit Right and

Limit Subwoofer displays on L.U.C.A.S IMPACT’s
control panel. These may light up yellow, but only
intermittently. Under no circumstances may they
continuously illuminate yellow. If this is the case,
turn the Gain down (knob counterclockwise).

Annoying hum

1 Check the cables connecting the source of the

audio signal to L.U.C.A.S IMPACT. Replace any
damaged cords.

2 If you cannot pinpoint the cause of the humming,

press the Ground switch in. This should remedy

the problem in most cases.
