L-Acoustics LA4X

The LA4X is an amplified controller based on a four input by four output architecture combining the benefits of the self-powered speaker packages with the flexibility of outboard DSP and amplification. L-ACOUSTICS loudspeaker enclosures can be driven by the LA4X in three different modes: “à la carte” - where the 4 inputs/4 outputs are allocated to passive enclosures in a one-to-one link, “full active” - a fully discrete power and DSP drive for active enclosures, “conventional” - connecting multiple enclosures in parallel. The LA4X features a green SMPS power supply with PFC. Its high efficiency class D amplification is capable of delivering 4 x 1000 W power at 8 Ω or 4 Ω with class leading hold times. Other notable features include AES/EBU as standard and extensive DSP resources per output: 1000 ms of delay, a comprehensive EQ station including the exclusive Array Morphing tool together with 8 IIR, 3 FIR and air absorption compensation filters and advanced L-DRIVE protection. All with Ethernet networking and a powerful yet simple to use interface backed by a firmware with ultra-fast start-up time.
