Welcome to the HK Audio family!
Thank you for choosing (yet another) HK Audio product!
PREMIUM PR:O active enclosures are end-to-end sound reinforcement
solutions comprising loud-speakers, power amps, and integrated
circuitry precision-tuned to control these components. These satellites,
bass bins, and monitors may be combined with one another. Deployed
as standalone enclosures, they readily integrate into other sound
reinforcement systems. Feel free to connect passive loudspeakers –
ideally, a passive PREMIUM PR:O Series enclosure - to the parallel
circuits of all active models except the PR:O 18 Sub A and the
PR:O 210 Sub A to extend your system without having to add another
power amp to your rig. What’s more, our engineers developed new
technologies specifically to maximize the performance of PREMIUM
PR:O active cabinets.
Warranty
Register your PREMIUM PR:O using the enclosed warranty card to
extend your warranty to five years free of charge!
Important note: Be sure to register each PREMIUM PR:O powered
enclosure individually.
To this end, use the convenient online registration option at
www.hkaudio.com.
If you are unable to register online, please complete the enclosed
warranty card completely and mail or fax it to us. Registration is only
valid if the warranty card is filled out and returned to HK AUDIO or the
device is registered via Internet within the registration period. We are
also interested in learning where and by whom our devices are used.
This information will help us design future products. Your data are of
course protected by privacy laws.
Thank you!

Digital Amping – Enhanced efficiency and dynamics
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 attenuation factor is higher, resulting in perceptibly
more responsive and accurate performance.
RMS/Peak-Limiter
A smart combination RMS / Peak Limiter achieves balanced dynamic response at high loads
while protecting components against overload. (The PR:O 18 Sub A and the PR:O 210 Sub A come
without an RMS Limiter.)
Subsonic-Filter – Protection against low-frequency rumble
The integrated subsonic filter eliminates accidental and unintentional signals such footfalls, wind,
or the sound of a hand inadvertently brushing a microphone. It cuts these frequencies drastically,
freeing energy to better render bass impulses. The result: delightfully dynamic and natural-
sounding low-end response.
DuoTilt 3/7™ – Making the most of sonic energy
The specially developed DuoTilt™ pole mount allows sound energy to be utilized far more
efficiently. DuoTilt™ offers 3° and 7° angles of tilt, enabling perfect satellite-to-audience
alignment. Troublesome ceiling reflections are minimized, yielding a clearer, punchier, and tighter
sonic image. MonoTilt™ (PR:O 8 A) offers one angle of tilt.
