L-Acoustics LA4X User Manual

Introduction
LA4X amplied controller
The LA4X is an amplied controller based on a 4-input by 4-output architecture and an exclusive green power module
providing maximized efciency. With LA4X, L-Acoustics speakers can get all the benets of self-powered speakers, while
keeping the versatility of the separated amplication approach.
The L-Acoustics systems can be operated in three connectivity modes:
"A LA CARTE" The pool of four inputs and four amplication 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 +
amplication / 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 + amplication / transducer section).
"CONVENTIONAL" For applications requiring a high count of loudspeaker enclosures with optimized cost of
amplication, the LA4X can efciently operate as a conventional amplied controller driving
speakers in parallel from its four amplication channels, with the added benet of the 4 inputs
when using passive loudspeaker enclosures.
