At the heart of the L-ACOUSTICS
edge loudspeaker amplification, DSP, network control, and comprehensive system protection in a single ergonomic
package.
Based on similar platforms, the exceptional and ground-breaking performance level delivered by the LA4 and LA8 units
allow full optimization of the resources of all L-ACOUSTICS
with the best possible transducer protection.
The LA4 and LA8 share the following characteristics:

A 2U lightweight format for high amplified density.
 A four-channel high efficiency amplifier section fed by two inputs.

A DSP section featuring advanced filter algorithms and an exclusive L-DRIVE protection system for the
transducers allowing optimum system performance.
 An on-board preset library to cover all the principal L-ACOUSTICS

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 LA4 and LA8 units, remote-monitored by LA NETWORK
MANAGER software (Windows
And the specific features of each unit are the following:

The LA4 delivers up to 4 x 1000 watt into 4 ohm.

The LA8 delivers up to 4 x 1800 watt into 4 or 2.7 ohm.

An AES/EBU input card is integrated to the LA8 for digital audio implementation. This feature is available as an
option on the LA4.
 The LA8 includes all current factory presets while the LA4 only includes presets of LA4 type.

The output connectors are SpeakON
The unique ensemble of on-board features and the addition of peripherals are all offered in a secured and standardized
environment. This approach simplifies system setting and operation with the benefit of superior and predictable audio
results across the entire product range.
Driving four amplified output channels through a DSP offers a wide range of options when it comes to sound system
configuration. The LA4 and LA8 on-board preset libraries allow the sound engineer a high degree of flexibility in
choosing the enclosure models and the system configuration for a specified application.
The factory preset libraries are derived from 6 basic system templates:

3-way active mono, quad-amplified

cardioid subwoofer mono

2-way active stereo

passive stereo

hybrid active/subwoofer mono

hybrid passive/subwoofer stereo
