1 INTEGRATED SYSTEM APPROACH

1.1 Presentation

The LA4X is an amplified controller based on a 4-input by 4-output architecture and an exclusive green power module

providing maximized efficiency. With LA4X, L-ACOUSTICS

speakers can get all the benefits of self-powered

speakers, while keeping the versatility of the separated amplification approach.

1.2 System configurations

The L-ACOUSTICS

systems can be operated in three connectivity modes, as described below:

‘‘A LA CARTE’’

The pool of four inputs and four amplification channels of the LA4X can be allocated “à la

carte” to any passive speaker enclosures with a one-to-one-to-one link (input /

processing+amplification / loudspeaker). This approach is cost effective for applications

requiring a high count of independent sound sources such as stage monitors, multi-channel

systems and multi-feed distributed systems.

‘‘FULL ACTIVE’’

In high-end installation projects, the LA4X can drive active systems, up to K2, for maximum

power headroom and the best possible performances. With one transducer section per

output channel and the independent DSP treatment of each output, this approach brings

maximum discretization with a one-to-one link (processing+amplification / transducer

section).

‘‘CONVENTIONAL’’

For applications requiring a high count of loudspeaker enclosures with optimized cost of

amplification, the LA4X can efficiently operate as a conventional amplified controller driving

speakers in parallel from its four amplification channels, with the added benefit of the 4

inputs when using passive loudspeaker enclosures.

1.3 System components

The system approach developed by L-ACOUSTICS

consists in offering a global solution that guarantees the highest

and most predictable level of performance at any step of loudspeaker system deployment: modeling, installation and

operation. A complete L-ACOUSTICS

system includes enclosures, amplified controllers, cables, rigging system, and

software applications. The main components of an L-ACOUSTICS

system that includes the LA4X are the following:

1.3.1 Powering and driving systems

LA4X

Amplified controller with DSP library and networking capabilities.

1.3.2 Loudspeaker enclosures and cables

Refer to the user manuals of the loudspeaker systems for detailed instructions about the enclosures and their

connection to the LA amplified controllers.

1.3.3 Rigging elements

Refer to the rigging manuals of the loudspeaker systems for detailed instructions about the rigging of the

enclosures.
