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 down

­ward 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

1 L.U.C.A.S SMART’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 SMART
system.

14 To Satellite Left/Right

Connect these Speakon® outputs to L.U.C.A.S
SMART’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 SMART 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.

16 Mains Input

Caution! Make sure the local mains voltage matches

the voltage specified on the rear panel of L.U.C.A.S
SMART. If you connect the L.U.C.A.S SMART system
to the wrong mains voltage, you can damage its elec­tronic components.

17 Power Switch

L.U.C.A.S SMART on/off switch. The light within the
switch will glow red to indicate that it is powered up.

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

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 (stereo­style) 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 SMART 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 SMART 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 mm2 to 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 SMART
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 SMART 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 SMART 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 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 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 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 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 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 frequen­cies, simply turn the Subwoofer Level knob to the
left (down to -12 dB) or right (up to +6 dB).

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 SMART
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 SMART 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 SMART 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 SMART system. To prevent
this problem, always be sure to connect L.U.C.A.S
SMART 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 SMART’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 SMART’s Gain knob (Line
In or Aux In).

• Observe the LEDs of the Limiter Status displays on
L.U.C.A.S SMART’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 SMART. 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.
