L-Acoustics LA7-16I-US Install Amplified Controller - 16x 1300 Watt at 8 Ohms - US Version

LA7.16i is a 16-channel amplified controller dedicated to permanent installations. It integrates L-SMART power management technology to dynamically match the real-time needs of the loudspeaker system being driven. LA7.16i is efficiently dimensioned for multichannel applications, distributed systems, or line sources for the finest discretization.

Its streamlined and elegant 2U 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-compliant LA7.16i supports AVB inputs with seamless network 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.
