The transducers are implemented in a K- shape conguration. The K1 enclosure is based on a 3-way active design with 2 LF sections, 1 MF section and 1 HF section, each one at the nominal impedance of 8 ohms. The K1 enclosure is made of rst grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity.
Introduction How to use this manual The K1 owner's manual is intended for all actors involved in the system design, implementation, preventive and corrective maintenance of the K1 system. It must be used as follows: 1. Read the technical description for an overview of all system elements, their features, and their compatibilities.

Rigging system description K1/K1-SB On both sides, K1/K1-SB integrates two arms to connect another element of the rigging system, such as an enclosure or to a ying frame: • At the front, a sliding arm enables the inter-element angle setting and the inter-element front connection.

Rigging elements K1-BUMP K1-BUMP is a rigging frame designed for ying K1/K1-SB enclosure arrays. It features a central rigging bar with four Ø 22 mm shackles to secure security slings, K1-BPCHAIN and K1-DELTA. K1-BUMP also features a support plate to accommodate a laser inclinometer. See K1-BUMP (p.146).
Page 21
Rigging system description The central bar of K1-BUMP has two holes each for site angle adjustments. Adjust the central bar position for a front side or a rear overhang of the enclosure array. Front overhang Rear overhang The array site angle depends on the relative heights between the K1-BUMP’s front and rear hang points (motor chain lengths) and central bar conguration (front or rear overhang).
Page 22
K1-BPCHAIN is an adjustable extension chain compatible with K1-BUMP or K2-BUMP. K1-BPCHAIN has a WLL (Working Load Limit) of 3.15 t and is necessary for climbing-hoist setup. It allows to prevent the chain bag from lying in front of the enclosures located on top of the array.
0° - 10° K1-LASERMOUNT K1-LASERMOUNT is a support plate for mounting a laser inclinometer to the side of a K1 or K1-SB enclosure. K1-LASERMOUNT is installed at the rear of the enclosure, on the right side. Refer to Installing a laser inclinometer (p.145).
K2-LINK is designed as an interface between the K1 and K2 rigging systems. K2-LINK is used to hang K2 under K1, K1-SB, or K1-BUMP. Three holes at the top provide three angle settings between the top K2 enclosure and the bottom K1 element: 0.25°, 2.5°, and 5°.
Transportation K-BUMPFLIGHT K-BUMPFLIGHT is a modular ight-case used to transport the accessories of the K1 system. It is designed to hook and lift K1-BUMP directly from the ight-case without any physical handling. K-BUMPFLIGHT allows to transport up to two K1-BUMP and additional accessories in the removable tray: 1.
Rigging system description K1-CHARIOT K1-CHARIOT is a chariot designed for the transportation and storage of blocks of up to four K1 or K1-SB. Do not move or transport more than four K1 or K1-SB on K1-CHARIOT. K1-CHARIOT is intended for use only with L-Acoustics K1 and K1-SB Use with other equipment may result in instability causing injury.
Rigging system description K1-PLA K1-PLA is a dolly board that can be secured to the front of a K1 or K1-SB with two ball-locking pins. K1-PLA is intended for use only with L-Acoustics K1 or K1-SB. Use with other equipment may result in instability causing injury.
Rigging system description K1-CHARIOTCOV K1-CHARIOTCOV is a protective cover for a stack of four K1 or K1-SB enclosures. A zipper at the rear provides access to the connector plate of each enclosure. K1-COV/K1-SBCOV K1-COV and K1-SBCOV are protective covers for one K1 or K1-SB enclosure on K1-PLA.
Always refer to Soundvision for the safety factor of a mixed array. When ying a K1 array with a Kara II downll, the mechanical safety of all system elements must be considered. The indicated maximum limit applies to the K1 only.
Page 30
Soundvision calculations are based on usual environmental conditions. A higher safety factor is recommended with factors such as extreme high or low temperatures, strong wind, prolonged exposition to salt water, etc. Always consult a rigging specialist to adopt safety practices adapted to such a situation.

• K1/K1-SB line source: enhanced LF throw By providing the K1-SB with the same frequency response as the K1 low section, the [K1SB_X] preset allows the K1-SB enclosure to be used as an LF line source element, increasing the length of the sub-low line source.
Page 32
2 K1 : 1 K1-SB Minimum line length 8 K1 + 4 K1-SB When using [K1] with [K1SB_X], do not add any delay value between the K1 and K1-SB elements of a same line source. K1 owner's manual (EN) version 1.0...
There are two distinct applications for K1-SB in a K1 system: • As an LF extension in a line source for enhanced throw, using the [K1SB_X] preset with K1. • As a subwoofer for increased impact, using the [K1SB_60] preset.
Loudspeaker congurations Additional subwoofer system A K1 line source or a K1/K1-SB line source can be deployed with additional subwoofer enclosures to provide increased sub-low resources to demanding applications. Two subwoofer systems are available: • K1-SB for increased impact • KS28 for infra extension The recommended ratio is one K1 for one subwoofer, whether using K1-SB subwoofers only, KS28 subwoofers only, or a combination of both.
