ACTOR Manual 2.2

By choosing ACTOR, you have opted for a two-way
active PA system that weds leading-edge technology
to utmost ease of use. The ACTOR is a professional
tool designed specifically to satisfy the needs of even
the most demanding sound reinforcement
applications. The system comprises two compo­nents, the AT 112 A top for mid/high-range
frequencies and the AT 115 SUB A subwoofer for
bottom end frequencies.
The basic version of an ACTOR sound reinforcement
system consists of four AT 115 Sub A subwoofers and
two AT 112 A tops

All of the electronics required to operate any given
cabinet are integrated right into it. The power amp,
crossover, controller electronics, limiter and the
Dynaclip circuitry - a special design that delivers
massive bottom-end punch - share the same
housing with the loudspeakers to form a self­contained unit. Since this arrangement makes long
patch cords and passive components unnecessary,
and the electronics features circuitry precision-tuned
to the speakers, ACTOR delivers enhanced per­formance, excellent audio quality, fantastic pulse
response, and great overload protection. With all the
requisite components on board, every cabinet is an
self-contained sound reinforcement unit that is easy
to set up and connect - simply plug in the signal and
mains cords and you’re ready to roll without any
further sound checking and tweaking.

Opto Limiter

Fresh, Friendly Mid/High Frequencies

Since mid and high frequencies are a breed apart
from low frequencies, they are best handled with a
different type of signal processing. To this end, we
use a technology originally developed for high-end
recording, an opto-limiter. With its soft-knee attack,
this type of limiting is not at all harsh, but very
smooth, musical, and inconspicuous.
The original signal is barely modified, leaving
inherent dynamics and natural sounds intact.

• Signal quality is maximized by keeping the
distortion to a minimum

• Soft-knee attack yields smooth, sweet, and
inconspicuous limiting

• Non-invasive processing results in an unadulte­rated signal with natural sounding dynamics

DynaClip™ Limiter

Big, Brawny Low End, Peak Power Amp Performance

HK AUDIO DynaClip™ technology offers a dynamic
limiting function designed specifically for enhancing
low-bass 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, increasing effective output power.

• Greater low-end punch through more efficient use
of energy

• Improved impulse response achieved by compen­sating for the transient response of the speaker
diaphragm

• Fine-tuned for peak performance from the bass
power amp

OFR™

Optimized Frequency Response Technology

HK AUDIO’s unique OFR™ technology deliver
commanding yet well-balanced sound at every level.
It corrects for non-linear frequency response in the
speaker components at the same time as it compen­sates for the way human hearing works at varying
levels.

• Fine-tuned to each system

• Rectifies non-linear frequency response

• Adapts the system to different volumes

• Powerful, balanced sound in every situation

Subsonic Filter

Preventing Low Frequency Interference

The integrated subsonic filter eliminates accidental
and unintentional signals such footfalls, wind, or the
sound of a hand accidentally brushing a microphone.
It cuts these frequencies drastically, freeing energy to
render bass impulses better. Goodbye squashed
dynamics and artificial sound, hello authenticity and
natural sounding low/mid frequencies.

• Increases power and volume in the useful
frequency range

• Protects power amps and speakers from harmful
ultra-low frequencies

Easy Setup and Handling

Less Pre-Gig Stress for a Better Show

All HK AUDIO Active Systems were designed as
cohesive units consisting of perfectly matched
components. Painstaking effort was invested in
developing systems that are easily transported and
swiftly set up. Operation couldn’t be easier; endless
tweaking is a thing of the past.

• A true system design: All components were
perfectly matched for performance as a unit.

• Fast set-up and effortless handling saves time and
spells less pre-performance stress.
