With high-performance amplification, digital signal processing and intelligent speaker protection, L-Acoustics' amplified controllers deliver high performance. The on-board preset library allows systems to be optimized very quickly with a minimum of decoration and equalization, and ensures that all L-Acoustics systems have the same sonic signature.The LA12X is the most powerful unit in the line. Thanks to its universal switched mode power supply (SMPS) with power factor correction (PFC) controlled by the digital signal processor (DSP), it delivers high power output for exceptional duration, even when connected to non-optimal power sources. It offers maximum versatility with its 4x4 architecture and ability to drive all L-Acoustics loudspeakers, including the KS28 reference subwoofer.
