Fonestar NMX-88 Digital Audio Matrix with DSP and 8 GPIOs

The Fonestar NMX-88 is a professional-grade 8 x 8 audio matrix designed for advanced signal processing and flexible audio distribution across diverse installation environments. With integrated DSP powered by ADI SHARC 21489 architecture, the NMX-88 is tailored for distributed audio, conference systems, and venue-wide AV installations. It supports extensive input/output control with advanced algorithms including echo cancellation (AEC), feedback cancellation (AFC), noise suppression (ANS), and automatic gain control (AGC), providing optimal audio quality and speech intelligibility. This matrix features modular configuration software with a customisable user interface and app control for Android and iOS touchscreens. With RS-232, RS-485, UDP, and Ethernet connectivity, along with support for PTZ camera tracking and 16 scene memory presets, the NMX-88 offers unmatched flexibility and control for audio professionals.
