SYSTEM APPROACH
4.1 LA8 Presentation
At the heart of the L-ACOUSTICS
®
complete system approach, the LA4 and LA8 amplified controllers offer high
performance loudspeaker amplification, DSP, network control, and comprehensive system protection in a single
ergonomic 2U package. Based upon similar platforms, the exceptional and ground breaking performance level delivered
by both the LA4 and LA8 allow for full optimization of all L-ACOUSTICS
®
system resources and deliver outstanding
audio quality combined with the best possible transducer protection.
Both the LA4 and LA8 share the following characteristics:
• A four-channel high efficiency amplifier section fed by two inputs, offering a power level matching for all L-
ACOUSTICS
®
loudspeaker systems
• A DSP section featuring advanced filter algorithms and an exclusive L-DRIVE protection system for the
transducers allowing for optimum system performance
• A complete on board PRESET LIBRARY developed for immediate use with a minimum of EQ correction,
optimized system resources and a unique sonic signature for all systems, and 10 user memory locations.
• An intuitive and ergonomic user interface, fully accessible from the front panel for standalone operation
• Two I/O Ethernet ports for networking up to 253 units
• The complementary LA NETWORK MANAGER Windows
®
software with remote monitoring and control of
all LA4 and LA8 units of the network
Specific features of the LA8 include:
• Up to 4 x 1800 Watts into 4 ohms
•
An integrated LA-AES3 AES/EBU board for digital audio input
• Two 4-point SpeakON
®
and one 8-pin CA-COM
®
connectors for loudspeaker outputs
4.2 Loudspeaker system configurations
Driving four amplifier output channels through a DSP offers a wide range of options when it comes to sound system
configuration possibilities. The LA4 and LA8 onboard DSP preset libraries allow the Sound Engineer a high degree of
flexibility through the use of the 6 following configurations:
• 4-way active mono system.
• 2-channel stereo system (for subwoofers or passive enclosures).
• 2-way active stereo system.
• Hybrid mono system (for subwoofers and active enclosures).
• Hybrid stereo system (for subwoofers and passive enclosures).
• Cardioid mono subwoofer system.
