KARA UM EN 5 0 www l acoustics com 2,SAFETY INSTRUCTIONS. 1 Read this manual, 2 Follow all SAFETY INSTRUCTIONS as well as DANGER and OBLIGATION warnings. 3 Never incorporate equipment or accessories not approved by L ACOUSTICS. 4 Read all the related PRODUCT INFORMATION documents before exploiting the system. The product information document is included in the shipping carton of the related system component. 5 Read the RIGGING MANUAL before installing the system. Use the rigging accessories described in the rigging manual and follow the associated procedures. 6 Beware of sound levels, Do not stay within close proximity of loudspeakers in operation and consider wearing earplugs.
Loudspeaker systems are capable of producing very high sound pressure levels SPL which can instantaneously lead. to permanent hearing damage to performers production crew and audience members Hearing damage can also. occur with prolonged exposure to sound 8 h at 90 dB A 30 min at 110 dB A less than 4 min at 130 dB A. The following symbols are used in this document, This symbol indicates a potential risk of harm to an individual or damage to the product. It can also notify the user about instructions that must be strictly followed to ensure safe installation or operation of. the product,OBLIGATION, This symbol notifies the user about instructions that must be strictly followed to ensure proper installation or. operation of the product,INFORMATION, This symbol notifies the user about complementary information or optional instructions.

KARA UM EN 5 0 www l acoustics com 4,1 KARA WST SYSTEM. With a design inspired from the K1 stadium system the KARA WST system is the high end modular line source from L. ACOUSTICS Utilizing the unrivalled characteristics of WST Wavefront Sculpture Technology the KARA system. delivers clarity precision and a unique proximity effect for the audience to enjoy an incomparable listening experience. The main system components are as follows, KARA full range element operating from 55 Hz to 20 kHz. SB18 low frequency element operating down to 32 Hz. LA RAK touring rack fitted with three LA8 amplified controllers. LA4X amplified controller, The KARA delivers a considerable number of improvements over the previous generation of line sources particularly. with regard to directivity control in the horizontal plane transducers resources for increased operating bandwidth and. coherence vertical coverage capability and extensive choice of operating modes to accommodate various LF contour. requirements, The compact size and low weight of a KARA line source complies with rigging and visual limitations Any on site. deployment can be easily and quickly achieved thanks to an extremely ergonomic rigging system. A wide range of system configurations are available for the sound designer and system engineer allowing high level of. creative freedom With a fixed horizontal directivity of 110 and a vertical inter element variation from 0 to 10 the. KARA line source is fully configurable to match any audience geometry The KARA system can be deployed either as a. main system FOH or distributed with the SB18 subwoofer as a compact complementary system delays or fills and. even as a dedicated K1 downfill extension for stadium and arena concert applications Before installation these. configurations can be acoustically and mechanically modeled with the SOUNDVISION 3D simulation software. As a distribution platform for power audio signals and network the LA RAK touring rack fitted with three LA8 amplified. controllers is the heart of the system Thanks to dedicated factory presets it constitutes an extremely advanced and. precise drive system for the enclosures In high end installation projects the LA4X amplified controller can deliver. maximum power headroom and the best possible performances With one transducer section per output channel and. the independent DSP treatment of each loudspeaker enclosure this approach brings maximum discretization with a one. to one to one link from input to processing to enclosure All L ACOUSTICS amplified controllers feature the L DRIVE. a thermal and over excursion protection circuit, Up to 253 LA8 amplified controllers can be connected together via the Ethernet based L NET protocol The LA.
NETWORK MANAGER software allows online remote control and monitoring of all the connected units via a user. friendly and intuitive graphic interface and features the Array Morphing EQ This exclusive tool allows the engineer to. quickly adjust the tonal balance of the system to reach a reference curve or to ensure consistency of the sonic signature. KARA SYSTEM and KARAi SYSTEM, In this document the KARA term and illustration will refer equally to KARA or KARAi In the same way. the SB18 term and illustration will refer equally to SB18 or SB18i These products are different versions of. the same enclosure and share the same operating modes presets and recommended configurations The. rigging system of each version has been designed to accommodate a different use KARA and SB18 are. optimized for touring market whereas KARAi and SB18i are optimized for fixed installation.
