Introduction
LA4X amplied controller
The LA4X is an amplied controller based on a 4-input by 4-output architecture and an exclusive green power module
providing maximized efciency. With LA4X, L-Acoustics speakers can get all the benets of self-powered speakers, while
keeping the versatility of the separated amplication approach.
The L-Acoustics systems can be operated in three connectivity modes:
"A LA CARTE"
The pool of four inputs and four amplication channels of the LA4X can be allocated "à la
carte" to any passive speaker enclosures with a one-to-one-to-one link (input / proc
amplication / 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 (proc amplication / transducer section).
"CONVENTIONAL"
For applications requiring a high count of loudspeaker enclosures with optimized cost of
amplication, the LA4X can efciently operate as a conventional amplied controller driving
speakers in parallel from its four amplication channels, with the added benet of the 4 inputs
when using passive loudspeaker enclosures.
