L-Acoustics L-ISA Multichannel Audio Processor MkII - The Ultimate 16-Output Audio Powerhouse
Revolutionize your audio experience with the L-ISA Processor II! This licensed-based processor is a game-changer for real-time spatial audio processing. Whether you're working on a small installation or a large-scale tour, it offers state-of-the-art object-based mixing for immersive audio production.
- • 128 inputs and up to 128 outputs using AVB or MADI protocols for versatile connectivity.
- • Process up to 96 objects with spatial processing parameters and the patent-pending room engine for immersive sound.
- • Render objects to up to 128 outputs at 96 kHz depending on the license pack selected for high-quality audio.
As a matrix, it allows seamless routing of any input through spatial processing or directly to any output, enabling media format conversion and AVB stream multiplexing. The ruggedized chassis with two redundant universal power supplies ensures reliability. And as a Milan-certified device, it guarantees seamless Milan network redundancy for all AVB streams.
