Presentation

®
The L-ACOUSTICS LA8 amplified controller is at the heart of the L-ACOUSTICS
offers cutting edge loudspeaker amplification, DSP, network control, and comprehensive system protection in a single
ergonomic package. The LA8 performance level fully optimizes all L-ACOUSTICS
outstanding audio quality combined with the best possible transducer protection.
All L-ACOUSTICS ® loudspeaker systems will now benefit from the advanced and exclusive properties of the LA4 and
LA8 control platforms. As a result of the integrated approach all L-ACOUSTICS
by the superior performance of high end electronic platforms, allowing perfect power matching combinations across
the entire product range.
Packaged in a compact 2U lightweight format chassis the LA8 platform has the following characteristics:
• A 4 channel high efficiency amplifier section fed by two inputs that can deliver up to 4 x 1800 Watts
into 4 ohms yielding perfect power matching for a selected range of L-ACOUSTICS
• A DSP section featuring advanced filter algorithms (IIR and FIR) and an exclusive L-DRIVE protection
system for the transducers, allowing optimum system performance.
•
A complete on board preset library stored in 89 memory locations to cover all principal
loudspeaker system configurations for a selected speaker range, and 10 user memory locations.
•
An intuitive and ergonomic user interface plus display for all configuration settings and status
information, all fully accessible from the front panel.
•
Two I/O Ethernet ports to interconnect up to 253 units in multiple network topologies through the
L-ACOUSTICS
based LA NETWORK MANAGER software (Windows
•
Two NL4FC Speakon
•
A rear-panel plug-in card slot also allowing the LA8 to be ready for multi-channel digital audio
networking implementation (this option will be available as a future development).

System configurations

Driving four amplifier output channels through a DSP offers a wide range of options when it comes to 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 system template 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)
•
Cardioïd mono subwoofer system
