Welcome to the
HK Audio
®
family!
Thank you for choosing (yet another) HK Audio
®
product.
Perfect sound is the product of perfect tuning. This
is why the HK Audio
®
development team comprises
engineers specializing in acoustics, analog and digital
electronics, and mechanics. This tight-knit team
collaborates with a musicologist who tweaks the sound of every HK Audio
®
product to suit human
auditory physiology. HK Audio
®
developers have the
perfect tool for this at their disposal—one of the
world’s most advanced acoustical measurement
labs. It enables a speaker system’s audio properties
and dynamics to be documented and analyzed in
minute detail to ultimately advance the state of the
art. Every day in our sonic foundry is a day spent
with a singular goal in mind—to forge impressive sound reinforcement tools! So, what do mean
by impressive?
• Your voice (and every other audio signal) is rendered
accurately and authentically.
• Greater utilizable sound pressure is assured so that
the sound remains true and balanced right up to
the threshold of power-handling capacity.
• Remarkably well-balanced frequency response and
constant dynamic response requiring no further
EQ-ing.
• Listening fatigue never sets in: Disharmonic
distortion and resonance are minimized so the sound continues to please to your audience’s ears
even after long listening sessions.
• Plug in, power up and enjoy great sound right out
of the box: HK Audio
®
systems take you there that
much faster.

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
7.5° and 15° angles of tilt, enabling precise speakerto-audience alignment. Acoustic interference from
ceiling reflections is minimized, leaving the sound
cleaner, tighter, and much more articulate.
Passive Crossover
in Bass Systems
The PR:O 18 S bass bin sports a sophisticated crossover 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 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 12 and
PR:O 15 fullrange speaker cabinets, PR:O 18 S subwoofers and PR:O 12 M and PR:O 15 X monitors.

1 Aligning Cabinets with
DuoTilt™
The novel integrated DuoTilt™ pole mount allows
sound energy to be utilized far more efficiently.
With two angles of tilt to choose from, 7.5° and 15°,
the enclosure can be aimed directly at the audience.
The cabinet is stabilized at its center of gravity—no
wobbling, unwanted tilting, or unintentional turning.
Your choice of DuoTilt™ angle—7.5° or 15°—depends
on the required speaker height and the size of the
room. If you set mid/high units on fully extended
tripods or mounting poles, select 15° to minimize
ceiling reflections.
If you want to address an audience where more
listeners are farther away from the speakers, use
the HK Audio
®
DuoTilt™ at the 7.5° angle.
2 Connecting Components and
Speakers
HK Audio®speaker cords with a diameter of 2 x 2.5
sq. mm are recommended for connecting cabinets,
power amps or powered mixing consoles. Cords are
available in the following lengths:
1. LSC 3, item no.: 193283, 3 m
2. LSC 7, item no.: 193263, 7 m
3. LSC 15, item no.: 193323, 15 m
Recommended Amplifier Power Output
Connect amps rated from 600 W @ 4 W RMS to 800 W
RMS @ 4 W per amp channel to power the PREMIUM
PR:O cabinets. To have enough headroom available
for dynamic musical signals, the power amp should
deliver peak performance of at least 1,200 W @ 4 W
per channel.
Note:
An electrical connection between the cord and input
jack is not established until the Speakon connector
locks into place. Twist the Speakon connector clockwise until it engages.
2.1 PR:O 12, PR:O 15 and PR:O 15 X
in Full-range Mode
Connect the speaker output from the powered mixer
or power amp to the input (IN) of the PR:O 12 or
PR:O 15 (X) full-range speaker cabinet.
