The system approach developed by L-ACOUSTICS

®

 consists in offering a global solution that guarantee the highest and 

most  predictable  level  of  performance  at  any  step  of  loudspeaker  system  deployment:  modeling,  installation,  and 
operation. A  complete  L-ACOUSTICS

®

  system  includes  enclosures,  amplified  controllers,  cables,  rigging  system,  and 

software applications. The main components of a 

KARA SYSTEM 

are the following: 

 

2.1

 

Loudspeaker enclosures 

KARA 

Full-range enclosure (50 Hz – 20 kHz),

 

2-way active, variable curvature WST

®

 line source 

 

 

SB18 

High power compact subwoofer (down to 32 Hz) 

 

 

SB28 

High power subwoofer (down to 25 Hz) 

 

 

Loudspeaker system design 

Sound  design  aspects  are  beyond  the  scope  of  this  document.  However,  the  various  applications  of  the 
system will be based on the operating modes presented in this document. 

 

2.2

 

Powering and driving system 

LA8 

Amplified controller with DSP, preset library and networking capabilities 

 

 

LA-RAK 

Touring rack containing three LA8, for power, audio signals and network distribution 

 

 

Operating instructions 

 

Refer to the 

LA8 

and

 

the 

LA-RAK user manual

 

2.3

 

Loudspeaker cables 

DO cables (DO.7, DO10, DO25) 

8-point PA-COM

®

 loudspeaker cables 

respective lengths of 0.7m/2.3ft, 10m/32.8ft, and 25m/82ft 

 

 

DOFILL-LA8 

Breakout cable for two 2-way active enclosures  
PA-COM

®

 < 2 x SpeakON

®

   

 

 

DO3WFILL 

Breakout cable for one 2-way active enclosure and two passive enclosures 
PA-COM

®

 < 3 x SpeakON

®

   

 

 

DOSUB-LA8 

Breakout cable for four passive enclosures 
PA-COM

®

 < 4 x SpeakON

®

   

 

 

SP cables (SP.7, SP5, SP10, SP25) 

4-point SpeakON

® 

loudspeaker cables,  

respective lengths of 0.7m/2.3ft, 5m/16.4ft, 10m/32.8ft and 25m/82ft 

 

 

SP-Y1 

Breakout cable for two passive enclosure 
SpeakON

® 

< 2 x SpeakON

®

   

 
 
 

 

Information about the connection of the enclosures to the LA amplifiers is given in this document.  
Refer to the 

LA8 

and the 

LA-RAK user manual 

for detailed instructions about the whole cabling scheme, 

including modulation cables and network. 

 

2.4

 

Rigging elements 

 

 

Rigging elements or procedures are not presented in this document.  
According to the enclosure version, refer to the 

KARA

®

 

or

 KARAi SYSTEM rigging manual

 

2.5

 

Software applications 

SOUNDVISION 

3D acoustical and mechanical modeling
