L-Acoustics - LA2Xi CE - 4-Channel installation Amplifier
SKU: LA32007
L-Acoustics - LA2Xi
Primarily designed to power L-Acoustics compact loudspeakers, the bridgeable 4 x 4 channel LA2Xi offers anywhere from four to one output, allowing to also drive medium and large format loudspeakers, in full or reduced SPL, for various types of applications. Packaged in a 1U chassis for optimized rack space, LA2Xi is the ideal choice to power background music in leisure installations, distributed fill systems in performing arts centers, studio monitors, private auditoriums and more.
Underneath the streamlined front panel lies the same DSP engine as the flagship touring LA12X amplified controller, including features for loudspeaker management, protection and monitoring as well as a comprehensive set of tools for system adjustment and calibration. In addition to AES and analog inputs, the Milan-certified LA2Xi supports AVB with seamless network redundancy, ensuring utmost reliability. Tailor-made for integration applications, LA2Xi provides four user-assignable GPIO and a 24 V DC backup power for the DSP card, all on terminal blocks, enabling external control and monitoring, and ensuring fast recovery in case of power loss.
