The Sound of HK Audio.
We live in a world of sensory perception – touch,
taste, sight, and, particularly, sound! Hearing is like no
other sense. Auditory perceptions are interpreted as
information, but they also directly affect our emotions
and, by extension, our entire well-being. Language
and music are the speech of the heart, giving voice to
our feelings and making a shared experience of our
emotions.
Though we may not always be cognizant of it, we
immediately classify our perceptions of sound on
a scale ranging from ”Stop that noise!” to ”Crank
it!” There are many reasons why some sounds are
music to our ears. Our auditory perceptions have
been conditioned on an emotional level by thousands
of years of evolution. We are all equipped with
“algorithms” that tell us immediately if an audio event
signals safety, relief, good vibes, trouble ahead, or
even danger.
The better we understand these “algorithms”, the
clearer our acoustical objectives become when
developing speaker systems: We aim to render voices
and instruments with minimal coloration and utmost
authenticity. Or, to put it differently, we strive to build
cabinets that don’t sound like speakers.

The Experience of HK Audio.
PS_Kata_2007_Aufbau_25.indd 4
14.03.2007 12:20:23 Uhr
In 1979 when we started making speakers, these insights were of lesser concern to us. Lothar Stamer, the
founder of HK AUDIO, simply sought to build bettersounding, more practical alternatives to the systems
of the day. He painstakingly researched the functional
and acoustical properties of horns and documented his
findings in his master‘s thesis.
In the ensuing years, we developed close working
relationships with leading speaker manufacturers. Since
then, speakers built to our specifications have provided
the underpinning for all HK AUDIO systems.
Today the HK AUDIO developer team is made up of
many specialists. Engineers specializing in acoustics,
in analog and digital electronics, and in mechanical
engineering work hand in hand, collaborating with a
musicologist who adapts the sound of every HK AUDIO
product to suit human auditory physiology. A worldclass anechoic chamber/acoustical testing lab on site
is the perfect proving ground for these developers.
It enables our engineers to document and analyze the
audio properties and dynamics of a speaker system
in exhaustive detail to ultimately advance the state of
the art.

And the goal foremost in our mind always remains
the same – delivering authoritative sound that remains
true to the source!

Extraordinary reliability and exemplary audio properties – that’s what HK AUDIO cabinets are all about.
Relentless research and the unflagging desire to
take technologies up the evolutionary ladder set our
cabinets‘ apart from standard products, as their audio
performance attests.
But it takes more than merely matching components
to achieve excellent sound; they must be made to
harmonize perfectly. To this end, HK AUDIO engineers
have developed a host of new features and technologies,
which you’ll learn more about on page 47 of
this catalog.
All HK AUDIO active cabinets and powered systems
are end-to-end sound reinforcement solutions with
integrated electronics. From the drawing board to the
assembly line, we develop and optimize every system
for specific applications. Our engineers’ skills in
meticulously selecting and tuning all components is the
key to their stellar performance.
Each system comprises painstakingly selected features,
matched and fined-tuned for flawless performance, to
ensure it delivers the best possible performance for the
given application.

L.U.C.A.S – The next Generation
Within a few short months of its debut in 1998, the original
L.U.C.A.S system triggered a sea change on the market for compact
sound reinforcement systems. Exceptional depth and detailing from
soft to loud paired with ingeniously simple handling made it the
venerable progenitor of the entire HK AUDIO L.U.C.A.S product
family. In fact, it sired a new product category that sent many of the
conventional compact sound reinforcement systems scurrying for
cover, never to be seen again in some market segments.
L.U.C.A.S
The newest generation of this best-selling product family embraces
the first L.U.C.A.S generation’s sought-after features and leverages
state-of-the-art speaker and digital technology to attain an unprecedented level of performance. The original was a high-water mark in
system engineering, but the new generation, even more compact,
lighter, and able to deliver even more impressive sound with even
greater reliability, raises the bar even higher.

Every note is on the money, each instrument sounds sweet. The band is
well-rehearsed, tight like clockwork, and ready to strut its stuff in front
of their faithful fans. After all, the goal of every band is to pull off a
successful gig, play for an enthusiastic audience, and enjoy the pay-off
for all their efforts.
But the line between glee and gloom is thin. Among all the potential
fun-killers at gigs, the sound system is by far the most common culprit.
Hauling it demands brute force, and making sense of what seems like
miles of cable demands patience. Often, despite an epic-length sound
check, the system still fails to deliver decent sound. As if that weren’t
enough, the band is expected to play soothing background music
during the cocktail hour, and then kick out the jams for a blowout
bash to follow. Many systems for bands are heavy, hard to set up, and
complicated. Racks, power amps, cords, speaker stacks—even with all
this, it only manages to sound decent at a medium volume level. Turn it
up and the sound soon grates; back it off and it turns thin and puny.
Active Systems
HK AUDIO systems are designed to deliver full-spectrum sound that
uniformly maintains punch and dynamics all across the board from soft
to loud. These systems are remarkable in the amount of effective sound
pressure levels they produce; which is another way of saying that each
system always delivers optimal sound right up to peak volume. Even
without constantly tweaking knobs, HK AUDIO systems consistently
sound full and rich.

Fullrange
The Versatile Workhorse
Standard
Extended
A pub gig today, a show in a small art theater tomorrow,
and another event on the stage of the town fair on the
weekend—no sweat with ELIAS PX. Equipped with a
controller, crossover and power amp, every speaker unit
in the ELIAS PX system is a standalone solution that
does not require a central system controller to operate.
This affords you greater independence and flexibility
to adapt your rig to suit the situation: Leave the bass
bins behind for smaller gigs, and bring them along for
bigger venues.
For instance, you can opt to deploy the EPX 112 A Mid/
High unit as a full-range cabinet to achieve professional
results for voice public address in medium-sized venues
and for band gigs in pubs.
To treat your audience to a muscular low-end thump for
big, bold drums and other burly bass signals, simply set
up the entire system with the EPX 115 Sub A subwoofer.
Adding another pair of subwoofers to the sonic equation transforms the ELIAS PX into a full-grown PA that
lets bands play bigger halls and DJs rave it up.

ACTOR DX is an end-to-end active PA system featuring
the finest high-tech appointments. Its innovative
DDO™ technology puts an unprecedented dimension
in performance at your fingertips.
Experience has taught us that a digital controller
can only prompt the system to deliver premium
performance if that system is endowed with high-quality
components. This is why we engineered every
ACTOR DX setup to deliver state-of-the-art sonic results
even without the benefit of a controller. Add DDO™
controlling to the audio equation, and what is already
very good sound is transformed into an unsurpassed
sonic sensation.
ACTOR DX pairs top-drawer components such as the
1.4" driver and the potent digital power amps with the
novel DDO™ Controller. Boasting 56-bit computing
power, the latter is able to compensate speakers’
dynamic distortion, providing a richly detailed signal
free of discoloration.
With its extremely efficient components and revolutionary DDO™ controlling capability, ACTOR DX delivers
awesome punch and natural sound replete with crystalclear transparency at high levels and plenty of warmth
and fullness at even the lowest volumes.

PREMIUM PR:O System crossover
How does the PR:O 18 S’ crossover work?
When a speaker (such as an 18“ woofer) is operated
without an upstream crossover, it is asked to render the
musical signal’s entire frequency range: lows, mids and
highs. Be it a bass woofer, midrange speaker or a highfrequency driver, due to the very nature of its design
every speaker type is suited for rendering a certain
slice of the frequency pie. If it is operated outside of its
intended frequency range, it renders these frequencies
poorly or not at all. The signal will sound washed out,
unnatural and distorted.
The 18“ woofer was developed specifically for putting
the meat on the table—rendering low-end frequencies.
Its cone size, electrical load-handling capacity and low
resonance frequency enables it to generate frequencies
lower than roughly 150 Hz accurately, with plenty
of punch. The very properties that enable it to do
this prevent it from rendering mid-range and higher
frequencies correctly. If tasked to do this, the cone
generates partial vibrations. In simplified terms, these
incomplete oscillations generate frequencies that the
(original) music signal does not contain, which of
course compromises the soundscape’s integrity.
This is why high-quality speaker cabinets comprise
several components, and we speak of two-way or threeway speakers, usually a woofer, mid-range speaker and
high-frequency driver. To ensure that every speaker type
operates in its assigned frequency range, the musical
signal is split using passive crossovers.
A passive crossover consists largely of capacitors, coils
and resistors. Depending on the given combination
of components, filters with different characteristics
are used to limit the musical signal sent to the given
speaker, either via low-cut, high-cut, or a combination of
the two. The following filter types serve this end:
• Low-pass filter, also called a high-cut: This filter is used
for woofers. It filters all frequencies above the cutoff
frequency out of the musical signal.
• High-pass filter, also called a low-cut: This filter is used
for high-frequency drivers or to feed satellite speakers.
It filters all the frequencies below the cut-off frequency
out of the musical signal.
• Band-pass filter: The band-pass is a combination of
both filters. It is used for mid-range speakers to filter
out both high and low frequency ranges and allow a
narrow mid-range band to pass.
37
All three crossover
types are found in
The signal routing in the PREMIUM PR:O system
a three-way speaker.
(PR:O 18 S and PR:O 12/15/15 X) corresponds
difference being that the crossover circuits are
distributed to two enclosures: the subwoofer and
the mid/high cabinet.
The PR:O 18 S’ internal crossover prevents the woofer
from generating undesirable partial vibrations and
unburdens the mid-range speakers by routing the low
frequencies away from them.
PS_Kata_2007_Aufbau_25.indd 37
Both functions are vital to the sound quality and safety
of the overall system. An additional advantage is that it
spares the cost of purchasing an additional power amp
and an active crossover.

Please note that you’ll find an online System Check
for all our active systems at www.hkaudio.com.
14.03.2007 12:21:25 Uhr
A/D converter: Analog/digital converter, an electronic
component that transforms analog voltage curves, that is
signals, into binary information
AC: Abbreviation for alternating current
Active system: A sound reinforcement system with
integrated power amps.
ADP: Short for Advanced Driver Protection, an electronic
protective circuit for tweeters developed by HK AUDIO.
Aeroquip: Locking studs that engage in a rigging, aerial or
fly track and provide an eyelet for hanging cabinets
AES/EBU: A digital interface for audio data used primarily
in professional applications.
Alignment: The adjustment of delays in milliseconds to
ensure coherence among different speakers, for example,
to align different horns to compensate for the varying
depths at which drivers are mounted in the chassis.
Amp: Short for amplifier; also referred to as a power amp.
Aux bus: A mixing console output circuit for patching
signals to effect devices or monitor busses. Every aux bus
has an extra signal bus enabling the creation of a separate
mix that is entirely independent of the end mix. To this
end, each mixing console channel sports an aux knob that
adjusts the aux bus signal level.
Balanced: Symmetrical signal routing via audio lines with
three conductors, two carrying the signal and one the
ground or shield.
Balancing: Audio signals must be balanced to ensure
noiseless signal-routing across greater cable distances.
To this end, an inverted copy of the signal is routed via
second wire. At the destination, a useful signal is derived
from the inverted signal and in-phase noise induced along
the way is cancelled out.
Band-pass filter: Combination of high- and low-pass
filters. A band-pass filter allows a specific band of
frequencies between the upper and lower limiting
frequencies to pass and rejects frequencies above and
below this pass-band. Also: Bass cabinets whose speakers
radiate into a resonator chamber, generating high sound
pressure levels within a narrow frequency range (generally
low end).
Bass reflex system: Sound radiated to the rear of a
speaker is routed to a precision-tuned aperture at the
front of the enclosure and added in phase to the forward-moving sound waves to boost the cabinet‘s sound
pressure in the bass range.
Bi-amping: A crossover splits an audio signal into highfrequency and low-frequency signals, which are amplified
by separate power amps and rendered by separate
speakers.
Bypass: A circuit serving to reroute a signal, for instance,
past an effect device or an equalizer, so that it is not
processed.
Cable trunk: Crate for storing and transporting power,
audio and speaker cords.
Case: A stable transport box with metal fittings, butterfly
clasp and casters.
CD horn: CD is short for „constant directivity“. A CD horn
is designed so that all frequencies rendered by the driver
radiate outwards in a uniform horizontal and vertical
pattern.
Center cluster: Additional centrally arrayed or flown
speaker group, for example, to cover the audience in the
middle section and near the stage when cabinet towers
are situated far apart.
Circuit breaker: A device that automatically interrupts the
flow of an electrical current to protect equipment from
harm.
Class D: An amp operating mode serving solely to amplify
square wave signals. Class D or switch-mode amplifiers
serve to control step motors. The amplifier‘s transistor
stages do not require bias current, so class D power
amp‘s efficiency rating is over 90 percent. However, the
process of converting the input signal to PWM and
converting it back to analog, introduces considerable
distortion, requiring conventional feedback to reduce
distortion. See also A/B mode, digital power amp, PWM.
Clipping: When power amps, effect devices and mixing
console inputs are saturated with excessively high input
levels, these overdriven devices produce ugly distortion
(the top of a waveform appears to be cut off - hence the
term clipping). In overdriven power amps, DC voltage
is added to the output signal, which may endanger
connected speakers.
Cluster: A group of speakers.
Compander: Combination compressor/expander. When
a signal drops below a variable threshold, a compander
boosts the signal, and vice versa when it rises above
the threshold. This holds the signal at a constant level.
Though a compander would appear to extend the dynamic
range, it also raises the noise floor audibly at high gain
levels. Extreme attack and release time settings yield
noise tails and audible pumping. Frequently confused
with compressors, companders are quite popular with
guitarists because they boost a decaying signal to create
the impression of longer sustain.
Compressor: Control amplifier that reduces its gain
according to the compression ratio when a signal exceeds
the threshold. Threshold, ratio, attack and release are
adjustable. A compressor smoothes out the spikes in an
audio signal, thereby reducing the dynamic range.
Controller: A control unit tuned to a speaker system,
usually fully digitally in design. A controller‘s aligned
crossovers, limiters and delays ensure optimum
performance in terms of frequency, level and time. Most
controllers are designed so that operating error cannot
harm the speakers.
Crossover: Also called an x-over, a crossover splits a
frequency spectrum into different signal paths (2-way /
3-way). A distinction is made between active and passive
crossovers. Active crossovers receive a fullrange signal
directly from the mixer (line signal), which they then
separate and send to different power amps. Passive
crossovers are installed in a speaker cabinet. They
distribute the incoming amplified signal to the speaker
components inside.
Cue: A signal prompting the start of a specific action,
for example, to play back a piece of music. The term is
frequently used for the pre-fader listening function on
tape decks and DJ consoles.
Curve: The process of bending flown cabinet clusters to
create an optimum arc.
dB: Short for decibel, a numerical expression of the
relative loudness of a sound. The lower limit of audible
sound is equivalent to 0 dB, and a 3 dB change in level is
the smallest perceptible in level, which requires twice the
acoustical energy to achieve.
DC: Abbreviation for direct current.
DDO™ technology: Active compensation of dynamic
distortion. Every speaker has a specific tonal character.
Its timbre varies as volume levels vary. And due to its
transient response, an amplified signal rendered by a
speaker is not identical to the natural sound traveling
through air. The DDO™ (Digital Dynamics Optimization)
Controller (DFC) compensate for this dynamic distortion
with 56-bit computing power. The result is amazingly
assertive and authentic sound from a whisper to a roar.
Delay: In this context, the delay time of audio signals.
Delays (or echoes) are usually used as an effect. In large
venues and at open-air concerts it is often necessary to
set up additional cabinets to cover the audience area
furthest from the stage. Delay lines send a delayed signal
to align the front and rear cabinets‘ response.
DI box: Short for direct injection box. This signal
converter balances an unbalanced audio signal and
matches impedances so it can be sent to the mixing
console even via long cords. Equipped with an integrated
ground lift switch, it can also be an effective tool for
defeating ground loops.
Digital amping: With an extremely high efficiency
rating topping the 90% mark, 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 attenuation factor audibly enhance the
speed and accuracy of the system‘s dynamic response.
Directivity: The spatial distribution of acoustic waves
radiated by a speaker or speaker cabinets.
DSP: Abbreviation for digital signal processor.
Duspol: A voltage tester used to check the power supplies‘
ground and connected neutral conductor.

DynaClip™: This dynamic limiter function minimizes the
inharmonic distortion caused by limiting and maximizes
energy efficiency.
Dynamic range: A signal processor‘s capacity to produce,
render or handle signals from the softest to the loudest
levels. Starting at a signal‘s noise floor, it extends all the
way up to the distortion threshold.
E LA: German abbreviation for Elektroakustische Anlagen
(electro-acoustic system). ELA systems are the remote
ancestors of contemporary PA systems. Today they are
used principally for voice reinforcement in large buildings,
community centers or on sports grounds. At the risk
of hurting some janitor‘s feelings, these permanently
installed systems are not up to the challenges of concert
sound reinforcement.
EQ: Equalizer. A device for shaping the sound of
audio signals. A graphic EQ is equipped with filters
with a fixed frequency and bandwidth, often arrayed in
octave increments. The filters cut and boost the gain of
individual frequency ranges. The filters of a 31-band EQ
are spaced at much finer frequency intervals, enabling
much finer filtering. Parametric equalizers enable even
more variable selection of filter frequencies. Usually the
filter quality (that is, the bandwidth surrounding the filter
frequency) is also adjustable.
Expander: Pretty much the opposite of to a compressor,
an expander extends an audio signal‘s dynamic range by
attenuating gain by a factor of < 1 when the signal dips
below a variable threshold. Soft signals grow even softer
and interference such as noise is reduced by the same
measure. At its most extreme setting, an expander is
actually a noise gate that shuts down the signal path.
Fader: A sliding control on a mixing console that adjusts
individual channel, subgroup and master signal levels.
Feedback: Feedback‘s symptom is an unpleasant-topainful whining or howling. Its cause is an output signal
recycled into a signal source‘s input, for instance when
a microphone or instrument picks up the speaker signal
and delivers it back to the reinforcement system.
Feedback killer: A signal processor that monitors a signal
path for resonances in the frequency response. In case of
feedback, it determines the feedback frequency and automatically inserts a steep notch filter with the quality and
attenuation required to suppress the feedback.
PS_Kata_2007_Aufbau_25.indd 45
F.o.H.: Front of house; the location of the main mixer on
which the venue or room sound is mixed
Frequency response: The output-over-input ratio of the
frequency spectrum as obtained from the output and
input signal of a microphone, amp, speaker and so forth.
If all frequencies are generated, rendered or processed
equally, the frequency response of the given device is
linear.
Fullrange: This term denotes that the entire frequency
spectrum is rendered. Unlike subwoofers and satellites,
which render select ranges of the overall frequency
spectrum only, a fullrange cabinet reproduces bass
frequencies as well as midrange and high frequencies.
Gain: A mixing console channel‘s input amplification.
Gain knobs serve to bring different input levels to the
same level, while the volume faders adjust the balance
of levels.
Gate: Electronic switch that mutes a signal path when its
level dips below a given threshold. It serves to suppress
hiss, hum and other undesirable noise during pauses or
breaks.
Ground lift: This switch separates the signal from the
chassis ground. It frequently eliminates ground hum.
Ground support: The base for truss system towers.
Equipped with castors, they serve to raise and lower
transoms.
Headroom: An expression for the amount of gain reserves.
In the case of sound reinforcement systems, it is essential
that the system has sufficient headroom to deliver clear,
uncompressed sound and ensure thermal reliability.
High-pass: This is an electrical filter (or crossover) that
allows all frequencies of a signal that lie above a specific
frequency (e.g. 130 hertz) to pass to other speakers.
Horn: A cone-shaped device that bundles acoustical
waves to determine speaker directivity.
Impedance: In signal sources and inputs‘ electrical
circuits, the resistance to the flow of an alternating
current. In speakers, microphones and pick-ups,
impedance is the product of the geometrical addition
of ohmic coil resistance and additional inductive and
capacitive components. Impedance therefore depends on
frequency, and is usually indicated in values referenced to
a frequency of 1 kHz.
In-ear monitoring: Rather than sending the monitor
mix to monitor cabinets, the signal is patched directly
to musicians‘ earphones. The advantages are greater
freedom of movement, consistent sound, softer stage
volumes, enhanced sound out front, and less PA transport
hassle because there are monitor cabinets and power
amps to lug.
L.U.C.A.S: Acronym for Lightweight Ultra Compact Active
System.
LED: Light-emitting diode. Besides serving as diodes,
LEDs are commonly used as visual indicators. Compared
with lamps, they cost less to produce, respond faster, are
more robust and smaller, have a longer lifespan, and
consume less power.
Limiter: An aggressive compressor with an ostensibly
infinite compression ratio. When a signal rises above
an adjustable threshold, gain is reduced so that the
output level no longer exceeds the threshold. Limiters
are primarily used to protect devices from overloads with
great damage potential for the entire system.
Line signal: This is an unamplified signal sent directly
from a sound source (say a keyboard or CD player) or a
mixer (via the master output or aux bus) and must be
amplified by a power amp to be heard.
Low Cut: This switch limits the lower frequency range
of a cabinet. In the case of the ACTOR mid-/high-range
unit, frequencies below 110 hertz are cut off when the
Low Cut switch is activated. The switch comes in handy
when the top unit is used with one or several subwoofers.
When deployed as a fullrange cabinet, the Low Cut switch
should be deactivated.
Low-pass filter: The opposite of a high-pass filter.
Frequencies below the limiting frequency may pass; those
above it are rejected.
Master: The end of the line for all mixing console signals.
The master faders are usually used to adjust a PA‘s overall
volume.
MIDI: An acronym for Musical Instruments Digital Interface, a standardized serial interface designed to connect
keyboards, sequencers, samplers and so forth. Mixing
console automations and preset scenes can be activated
and controlled remotely via MIDI messages.
Modulation: The process of varying the amplitude,
frequency, or phase of a signal. For example, modulation
serves to pack an audio signal onto a high-frequency
carrier and send it as a radio signal. A demodulator at the
receiving end extracts the intelligence from a signal by
rejecting the high frequency signal.
Monitor system: Speaker system serving solely the
purpose of on-stage sound reinforcement. In professional
productions, it is controlled from an ancillary mixing
console sited at the side of the stage.
Multi-Band limiting: Several matched limiters are finetuned to process the acoustically relevant frequency
ranges. This speaker-independent approach to signal
processing results in natural-sounding dynamic response
across the entire frequency spectrum and an assertive yet
finely balanced sonic image.
Multicore: Multiple-wire connecting cable running from
the stage to the mixer. It carries all audio signals and
sometimes digital MIDI or DMX data.
Mute: To silence a signal.

unprecedented technology, OFR™ delivers assertive yet
well-balanced sound at every level. It rectifies speaker
components‘ non-linear frequency response and adapts
the system‘s sound to suit the human ear‘s auditory
perceptions.
Opto limiter: The dynamic response of mid/high-range
speakers and bass woofers diverge, and therefore require
different types of signal processing. The Opto Limiter
is based on technology initially developed for high-end
recording gear. Its soft knee attack sounds more musical
and unobtrusive, making it ideal for processing high and
midrange frequencies. The signal‘s original envelope
remains virtually intact, ensuring far more naturalsounding dynamic response.
Overload: Overburden, saturate
Subsonic switch: A switch found on power amps. When
activated, the amp does not amplify frequencies below
20-30 Hz, thereby enhancing power amp efficiency. The
reasoning is that most cabinets are unable to render these
frequencies anyway.
Subwoofer: A speaker that is designed exclusively to
render bass frequencies.

DDO™ Controlling Technology
OFR™
Active Compensation of Dynamic Distortion
Optimised Frequency Response Technology
Every speaker has a specific tonal character. Like an instrument, a speaker’s timbre is not
static—it varies as volume levels vary. A speaker also generates distortion, partial oscillations and resonances. In a nutshell, its response is constantly changing. And in a system
comprising several speakers, these undesirable effects can be multiplied. This is where
the new patent-applied-for DDO™ (Digital Dynamics Optimization) technology comes
into play. Leveraging many years of experience with the HK AUDIO DFC (Digital Field
Controller), our engineers developed an extremely powerful controller that for the first
time compensates for these forms of dynamic distortion. The resulting sound is strikingly
clear and natural. Furthermore, it is stable and easily controlled from a whisper to a roar.
To adapt the rig more easily to different applications and configurations, the DDO™
Controller offers various presets.
For detailed information on DDO™ visit www.hkaudio.com.
Multi-Band Limiting
An unprecedented technology, OFR™ delivers commanding yet well-balanced sound at
every level. It rectifies speaker components’ non-linear frequency response and adapts
the system’s output to suit the specific response of the human ear.
Opto-Limiter
For the mid-range/high range
Mid-range and high frequencies are a breed apart from low frequencies, and they require
a different brand of signal processing. To this end, we use an opto-limiter, a technology
originally developed for high-end recording. Its soft-knee response ensures smoother,
more musical limiting that works inconspicuously. The source signal remains largely
intact for more dynamic and natural-sounding response.
Optimised for every frequency range
Several limiters function in tandem to process all key frequency ranges. This achieves
balanced dynamic response and punchy projection for highly musical sound across the
entire frequency spectrum.
Subsonic Filter
Protection against low-frequency rumble
The integrated subsonic filter eliminates unintentional LF signals such footfalls, wind,
or the sound of a hand inadvertently bumping a microphone. It cuts these frequencies
drastically, freeing energy to better render bass impulses. The result: delightfully dynamic
and natural-sounding

Enhanced efficiency and dynamics
HK AUDIO‘s DynaClip™ technology entails a dynamic limiter function developed
specifically to enhance low-end performance. The DynaClip™ Limiter compensates for
the subwoofer’s slower initial transient response, audibly improving pulse behavior. This
makes the most of low-frequency energy, and enhanced efficiency translates to more
available power.
With an efficiency rating topping the 90% mark, digital power amps are smaller, lighter,
and more compact than 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 perceptibly more responsive and accurate performance.
TiltUnit™
System Crossover in the Subwoofer
Making the most of sonic energy
For uniform sound
DuoTilt™, MonoTilt™ and MicroTilt™ pole mounts allow sound energy to be utilised
more efficiently. DuoTilt™ offers angles of 7.5° and 15°, and MonoTilt™ and MicroTilt™ an angle of 10°, to better aim mid/high-range cabinets directly at the audience.
Interfering ceiling reflections are substantially decreased; the soundscape is clearer,
tighter, and more focused.
The crossover ensures that each loudspeaker precisely renders just the frequency
range for which it is designed, and that spells superior performance. In addition, it
improves the consistency of overall system impedance, therefore assuring more effective
distribution of the power amp’s output. This serves to create a homogeneous sound
system that is not plagued by phase issues and washed-out sound.
