K2 RIGGING SYSTEM

The system approach developed by L-ACOUSTICS

consists in providing packaged solutions for loudspeaker systems

in order to guarantee the highest and most predictable level of performance at any step: modeling, installation, and
operation. An L-ACOUSTICS

loudspeaker system is the set of components available to form any loudspeaker system

based on one of the full-range loudspeaker enclosures afforded by L-ACOUSTICS

. It includes enclosures, rigging

accessories, loudspeaker cables, amplified controllers and software applications.

The main components involved in the rigging process of a

system are the following:

1.1

Loudspeaker enclosure

Full range enclosure, deployable in a variable curvature line source.

K1-SB

Dedicated subwoofer enclosure, deployable with K2.

1.2

Rigging elements

K2-CHARIOT

Transport dolly for four K2 enclosures.

K2-JACK

Tilt adjustment screw jacks and bar for K2-CHARIOT

K2-BUMP

Rigging frame used to fly K2 line arrays. Designed to be compatible with K1 and K1-SB.
Provided with two bow shackles WLL 3.25 t.

K2-BAR

Rigging bar designed to provide a wider range of site angles for the K2-BUMP.

Provided with two bow shackles WLL 3.25 t.

K1-DELTA

Rigging plate designed to be used optionally with the K2-BUMP, to adjust the azimuth angle

of flown K2 / K1 / K1-SB arrays.

K2-BUMPFLIGHT

Flight-case dedicated to the rigging elements of the K2 system.
In order to be used as storage for the K2-BUMP it must be prepared using the foams

provided with the product.

K2-LINK

Rigging interface between K2 and K1 or K1-SB.

K2-RACKMOUNT

Rigging interface for stacking one or two LA-RAK on top of a K2 array flown with a K2-

BUMP.

K1-BPCHAIN

Adjustable sling used to prevent the chain bag of a climbing hoist being in front of a flown
array top enclosure.

LA-SLING2T

Chain sling with two-leg bridles used to implement bridle hangs.

K2-RIGBAR

Light rigging bar and pullback accessory (incl. LA-SLING2T).

1.3

Software application

SOUNDVISION

Proprietary 3D acoustical and mechanical modeling software.

1.4

Transportation and storage accessories

K2-CHARIOTCOV

Protective cover for transportation and storage

Other K2 SYSTEM components

All the other components of the system are presented in the

user manual

, document intended to

describe the enclosure configurations and connection scheme.
