The L-ACOUSTICS
®
LA-RAK Touring Rack is the central element of the new L-ACOUSTICS
®
system architecture
built upon the LA8 amplified controller. It offers an advanced rack solution for all L-ACOUSTICS
®
systems covering
signal and power distribution in a comprehensive plug and play touring package. LA-RAK was created as a universal
platform designed to facilitate cross-rental and to ensure compatibility with the legacy analog cabling standard of
L-ACOUSTICS
®
systems.
The components of the LA-RAK related L-ACOUSTICS
®
systems are as follows (see Figure 1):
K1, KUDO
®
, V-DOSC
®
Full range active 3-way WST
®
enclosures
K1-SB Arrayable LF enclosure for K1
dV-DOSC, ARCS
®
Full range active 2-way WST
®
enclosures
dV-SUB Subwoofer extension for dV-DOSC
115XT HiQ Full range active 2-way coaxial enclosure
SB118, SB28 Subwoofer enclosures
LA-RAK Amp rack for three LA8 amplified controllers
LA NETWORK MANAGER Remote control software
SOUNDVISION Acoustical and mechanical 3D modeling software
The LA-RAK is compatible with standard L-ACOUSTICS
®
accessories. These accessories include the L-ACOUSTICS
®
DOM2 and DOM30 analog signal cables with respective lengths of 2 m/6.5 ft and 30 m/100 ft. These cables are for
connecting an analog sound source (mixing console or EQ device) to the LA-RAK or for linking two LA-RAK. Each cable
is a symmetric 6-pair cable fitted with PA-COM
®
19-pin female connectors (CA-COM
®
compatible). Note: Connection
to the XLR outputs of the analog source needs the addition of the DOMP-2 and DOMF cables (see section 6.6.1).

loudspeaker cables. The respective lengths are 0.7 m/2.3 ft for a ‘‘.7’’ cable, 10 m/32.8 ft for a ‘‘10’’
cable, and 25 m/82 ft for a ‘‘25’’ cable. These cables allow connection of the enclosures directly to the LA8 amp
outputs. Each cable is a 4 or 8-conductor cable with 4 mm
2
conductor cross-section (13 SWG, 11 AWG) and features
Speakon
®
NL4 and/or PA-COM
®
8-pin connectors. For more details refer to each enclosure’s
User Manual
as well as
the
‘‘LA8 – User Manual’’
(all available on the L-ACOUSTICS
®
web site).
Each system is driven and powered by the
L-ACOUSTICS
®
LA8 amplified controller. This ensures intelligent
protection, filtering, and equalization of the enclosures. Four amp channels are provided along with OEM factory preset
library for optimization of the system performances within the limits of the recommended configurations.
Each system design configuration should first be modeled and studied using the
L-ACOUSTICS
®
SOUNDVISION
software. The software predictions are based on the preset parameters stored in the amplified controller.
Up to 253 amplified controllers can be interconnected through the proprietary
L-ACOUSTICS
®
L-NET network and
be controlled using the L-ACOUSTICS
®
LA NETWORK MANAGER software. Note: An additional Ethernet
®
switch is necessary to achieve star network topology.
The LA-RAK is digital audio ready with sockets to connect to the proprietary
L-ACOUSTICS
®
L-DGA network. This
option will be available as a future development on the amplified controllers. Please check the L-ACOUSTICS
®
web
site on a regular basis for latest update.
Detailed description on the use of the LA8 amplified controller, SOUNDVISION and LA NETWORK MANAGER
softwares is beyond the scope of this manual. Please refer to the applicable documentation (available on the
L-ACOUSTICS
®
web site).
