L-Acoustics LA12X Amplified Controller 4x2600w 4-Ohms
L-Acoustics LA12X US Amplified Controller 4×2600-Watt 4-Ohms
L-Acoustics amplified controllers offer high performance and efficient loudspeaker amplification, digital signal processing and comprehensive system protection in a single ergonomic package. The onboard preset library allows for rapid system optimization with minimum EQ correction and delivers a unique sonic signature across all L-Acoustics systems. The LA12X is the most powerful unit in the range. Thanks to its DSP-controlled, universal Switched Mode Power Supply with advanced Power Factor Correction, it delivers high output power with outstanding hold times even on less-than ideal A/C mains. It offers maximum versatility with its 4×4 architecture and its ability to drive all L-Acoustics loudspeaker enclosures including the KS28 reference subwoofer.
