Product Overview

The MX-8400 is a professional 4-input/8-output digital audio processor from Harmonai, powered by a high-performance, high-speed ADI DSP processing chip and featuring 50 preset memory banks. Each input channel includes a 28-band graphic equalizer and 4 independent dynamic equalization channels. High-pass and low-pass filters are independently adjustable to enable asymmetric crossover functionality. Four independent feedback suppression channels effectively eliminate acoustic howl in sound reinforcement systems — making it the ideal control core for small-to-medium-scale live events, conferences, KTV venues, and other professional audio applications.
