Facts & Features
DuoTilt™ – making the most of sonic energy
The novel DuoTilt ™ pole mount allows sound energy to be utilised far more efficiently. DuoTilt™
offers 3° and 7° angles of tilt, enabling precise speaker-to-audience alignment. Acoustic
interference from ceiling reflections is minimized, leaving the sound cleaner, tighter, and much
more articulate. Mono Tilt 3™ (PR:O 8) offers one angle of tilt.
Passive Crossover in Bass Systems
The two PREMIUM PR:O bass bins sport a sophisticated cross over that sends all low-end
frequencies to the woofer and all mid-range and high frequencies to the connected satellite. This
frequency separation affords you the audio benefits of a truly homogenous sound system, free of
the pitfalls of overlapping phases that frequently plague lesser PAs.
Modular System
The PREMIUM PR:O Series is modular so that mid/-high units may be combined with the
PR:O 18 S / PR:O 210 S bass bin at will. This modularity extends to the acoustic domain: Like
every HK AUDIO system, PREMIUM PR:O Series components are meticulously matched. Regardless
of the PREMIUM PR:O Series configuration, you are sure to enjoy that trademark excellent
HK AUDIO sound!
Dynamic Protective Circuitry for the High-frequency Driver
PREMIUM PR:O Series mid/high units and monitors are equipped with special protective circuitry.
Located in the high-frequency signal path, it limits output levels whenever the high-frequency
signal level approaches the 1" driver’s overload threshold.
The PREMIUM PR:O Series comprises PR:O 8,
PR:O 12 and PR:O 15 fullrange speaker cabinets,
PR:O 18 S and PR:O 210 S subwoofers and
PR:O 10 X, PR:O 12 M and PR:O 15 X monitors.
