The L-ACOUSTICS
®
12XT active/passive enclosure is the mid sized model within the L-ACOUSTICS
®
XT
Coaxial Range and operates over the 55 Hz to 22 kHz frequency bandwidth. The system response can be extended
down to 32 Hz with the addition of the L-ACOUSTICS
®
SB118 subwoofer .
The system approach developed by L-ACOUSTICS
®
for the XT range 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 1and Figure 2):
8XT Passive compact coaxial enclosure
12XT Active/passive multipurpose coaxial enclosure
115XT HiQ Active coaxial stage monitor
ETR8-2 Mounting accessory for the 8XT enclosure
ETR12-2
Mounting accessory for the 12XT enclosure
ETR15 Mounting accessory for the 115XT HiQ enclosure
XTLIFTBAR Rigging accessory for the 12XT and 115XT HiQ enclosures
SB118 Subwoofer enclosure
LA4 Amplified controller
LA-RAK Touring rack containing three LA8 amplified controllers
LA NETWORK MANAGER Remote control software
SOUNDVISION Acoustical and mechanical modeling software
The XT range components are compatible with standard L-ACOUSTICS
®
accessories. These accessories include the
L-ACOUSTICS
®
SP.7 , SP10 , and SP25 loudspeaker cables with respective lengths of 0.7 m/2 ft,
10 m/30 ft, and 25 m/80 ft. These cables allow connection of the 8XT and 12XT enclosures to the LA4 amplified
controller. Each cable is a 4-conductor cable with 4 mm
2
conductor cross-section (13 SWG, 11 AWG) and features
4-point Speakon
®
connectors.
The
L-ACOUSTICS
®
DOFILL-LA8 cable allows connection of the 115XT HiQ enclosure to the LA8 amplified
controller. This cable features 8-point PA-COM
®
and 4-point Speakon
®
connectors and must be extended using the
L-ACOUSTICS
®
DO.7 , DO10 , or DO25 cables with respective lengths of 0.7 m/2 ft, 10 m/30 ft, and 25 m/80 ft.
Each DO cable is an 8-conductor cable with 4 mm
2
conductor cross-section (13 SWG, 11 AWG) and features
8-point PA-COM
®
connectors. Note: The PA-COM
®
standard is fully compatible with the CA-COM
®
standard.
ALWAYS connect the new DOFILL-LA8 cable on the LA8 amplified controller for active 2-way
applications, as using the old DOFILL cable may result in damaging the loudspeaker components .
The 8XT and 12XT are driven and powered by the
L-ACOUSTICS
®
LA4 amplified controller and the 115XT HiQ by
the LA8 . These controllers ensure intelligent protection, filtering, and equalization of the enclosures. Four channels of
amplification are provided along with the OEM factory preset libraries, ensuring the optimization and performance of
the systems within the limits of the recommended configurations.
The
L-ACOUSTICS
®
LA-RAK touring rack offers an advanced solution for all L-ACOUSTICS
®
systems covering signal
and power distribution in a comprehensive plug and play touring package. The LA-RAK was created as a universal
platform designed to facilitate cross-rental and to ensure compatibility with the L-ACOUSTICS
®
legacy analog cabling
standard.
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 controllers.
Up to 253 amplified controllers can be interconnected and monitored through the proprietary
L-ACOUSTICS
®
L-NET network using the L-ACOUSTICS
®
LA NETWORK MANAGER software.
Detailed description on using the LA4 and LA8 amplified controllers, SOUNDVISION and LA NETWORK MANAGER
software is beyond the scope of this manual. Please refer to the appropriate documentation, also available on the
L-ACOUSTICS
