KARA

SYSTEM

The L-ACOUSTICS

M-BUMPi and KARAiSB18LINK elements have been designed to rig the KARAi

Modular

WST

Line Source System.

The system approach developed by L-ACOUSTICS

for KARAi consists of the elements needed to fully take advantage

of the possible configurations and optimize the system. The main components of the system are (see also Figure 1 and
Figure 2):
