L-Acoustics | LA1.16i CE

LA1.16i is an ultra-compact 16-channel amplified controller dedicated to permanent installations. It is efficiently dimensioned for multichannel and distributed systems utilizing small format enclosures or for near-field applications.
Offering high channel density and versatile bridging functionality, LA1.16i integrates our patented L-SMART power
management technology to dynamically match the real-time needs of the loudspeaker system being driven. Its streamlined and elegant 1U chassis hides a powerful DSP engine with features for loudspeaker management, system protection, and monitoring as well as a comprehensive set of tools for system adjustment and calibration. The Milan-certified LA1.16i supports AVB or AES67 network inputs with seamless redundancy, in addition to AES/EBU and analog connections. Three GPIO and a 24 V DC backup power for the DSP card offer external control and increased reliability.
