L-Acoustics LA12X is the new amplified controller with 12,000 watts of power, thanks to its smart DSP-controlled Switch Mode Power Supply (SMPS) with Power Factor Correction. Boasting up to 3,300 watts per channel with record hold times, the LA12X is capable of operating from 100 to 240 volts while offering the highest tolerance to unstable mains. Universal SMPS ensures the LA12X can be taken around the globe while boosted DSP resources with AVB means the amp is future-ready. The most powerful amplified controller to date, the four-in-by-four-out architecture of the LA12X will make it a strong and economical choice for both rental and install projects.

The LA12X is also available with the LA-RAK II, an updated touring rack offering worldwide compatibility in one sole model.
