Digital Brain Instruments DSP Manager 2 - Loudspeaker Management System is a 64Bit standalone software developed to manage loudspeaker systems for studios, concerts, venues, conferences or any other kind of event that requires loudspeaker management or that requires audio routing to different loudspeaker systems. It allows managing complex loudspeakers systems (2-way & 3-way) using a computer, soundcard, midi controller and processing audio through vst/au plugins instead of a DSP hardware unit featuring crossover filters.
