L-Acoustics L-ISA Multichannel Audio Processor MkII with 16 Outputs

L-ISA Processor II is a licensed-based processor dedicated to real-time spatial audio processing. It provides state of the art object-based mixing for any immersive audio production, from the smallest installations to the largest tours. It offers 128 inputs and up to 128 outputs using AVB or MADI protocols. From the 128 selected hardware inputs, L-ISA Processor II can process up to 96 objects with spatial processing parameters and the patent-pending room engine. These objects can be rendered to as many as 128 outputs at 96 kHz depending on the license pack selected. Acting as a matrix, L-ISA Processor II allows the routing of any input through the L-ISA spatial processing or directly to any output, enabling media format conversion and AVB stream multiplexing. The ruggedized chassis integrates two redundant universal power supplies. As a Milan-certified device, L-ISA Processor II ensures reliability for audio distribution with the seamless Milan network redundancy for all AVB streams.
