L.U.C.A.S IMPACT Manual 1.2

1 L.U.C.A.S IMPACT System

Components

Subwoofer

The L.U.C.A.S IMPACT subwoofer’s housing is split

into two chambers. The front chamber serves as

the speaker cabinet for the 15" direct-loaded loud-

speaker, which has a power-handling capacity of

700-W and a nominal impedance of 8 ohms.

The active electronic circuitry, the power unit,

DDO™ digital controllers and Class D power amps

are housed in a separate compartment at the rear of

the cabinet.

Satellites

Satellites are loaded with a 8" HK AUDIO Custom

speaker and a 1" compression driver with a 60° x 40°

CD horn. They are rated for 250 W RMS power-hand-

ling capacity and a nominal impedance of 8 ohms.

The newly developed, integrated MonoTilt ™ pole

mount allows sound energy to be utilized with

great efficiency. Troublesome ceiling reflections are

minimized; the sound is clearer, tighter, and more

focused.

Beyond that, the cabinet is stabilized at its center

of gravity - no wobbling, tilting, or unintentional

turning.

2 Transport

To transport the system, simply set the subwoofer

on its casters and place the satellites onto the

subwoofer with the foam-rubber grille side facing

down. Secure the satellites, for example, using a

locking strap. Use original HK Audio L.U.C.A.S

IMPACT protective covers to gear up your personal

system for the rigors of the road. Amply padded and

protected against moisture, your L.U.C.A.S IMPACT

is sure to deliver satisfying performance for a long

time to come.

More about limiters

Limiters are designed to protect power amps and

the speakers connected to them from damage. The

functionality and response of a limiter is determi-

ned by parameters called attack time, threshold

and release time. Adjusting these parameters

incorrectly can degrade the sound and bring about

dynamic distortion. At peak volume levels, for ex-

ample, vocals may fail to cut through the mix and

instruments that are played percussively may lose

their punch and dynamics.

HK AUDIO limiting technologies are more than

merely technical tools serving to protect compo-

nents. We put a premium on authenticity, that is,

retaining an audio event’s true dynamics. This

explains why our limiters are first and foremost

designed to optimise the sound, though they of

course also protect the system.
