Unique features for premium performance
DDO™ Controller technology
The DDO™ Controller leverages 56-bit computing
power to compensate for the varying speaker-depen-
dent dynamic response of PA components such as
low-frequency woofers, midrange and high-frequency
speakers, power amps, and crossovers. DDO™
neutralizes undesirable discoloration caused by dis-
tortion, partial oscillations, and resonance, yielding
a crisp, assertive, and utterly natural-sounding sonic
image.
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
attenuation factor audibly enhances the speed and
precision of the system's dynamic response.
Multi-band limiting and companding
Several matched limiters and companders are fine-
tuned and optimized to process different frequency
ranges. This speaker-independent approach to
signal processing delivers natural-sounding dynamic
response across the entire frequency spectrum and
an assertive yet finely balanced sonic image.
Subsonic filter
The integrated subsonic filter cuts unwanted ultra-
low frequencies. Infra sub-bass signals resulting
from stage rumble, wind or similar sources place
heavy demands on the power amp to render fre-
quencies 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 power amps and speakers from harmful
ultra low frequencies
• Enables cleaner and tighter bass response and
higher output levels
Making the most of sonic energy with DuoTilt™
The DuoTilt™ 3/7 pole mount allows sound energy
to be utilized far more efficiently. It offers two angles
of tilt (3°, 7°), enabling the satellites to be aligned
precisely toward the audience. Troublesome ceiling
reflections are minimized; the soundscape is clearer,
tighter, and more focused.
Easy setup and handling for less pre-gig stress
Like all HK AUDIO active rigs, L.U.C.A.S ALPHA was
conceived as a cohesive system comprising painsta-
kingly matched components. This rig was enginee-
red for easy portability and swift set-up. Handling is
simple, with no complicated tweaking required.
• Genuine system design: All components are
precision-matched.
• Swift set-up & easy handling to save time
• Less stress = more fun + better music
