Product Overview

The Harmonai FBX-8600 is a professional-grade automatic feedback suppressor, built with a 56-bit high-speed DSP processor and 24-bit A/D-D/A conversion architecture. It delivers 1Hz frequency resolution and operates across the full audible spectrum of 20Hz–20kHz. Each channel features 12 dynamic notch filters and 8 static notch filters, totaling 20 precisely targeted notch points to locate and eliminate feedback frequencies.

The unit supports a dual-mode operation: auto-notch combined with frequency shifting, delivering exceptional acoustic feedback suppression. Built-in noise gating and input compression extend vocal dynamics while eliminating feedback. Independent 48V phantom power on both channels enables direct connection of condenser microphones, and an ultra-low-noise toroidal transformer ensures clean, stable power delivery.

Typical Applications

The FBX-8600 is ideal for conference sound reinforcement (meeting rooms, multi-function halls, auditoriums), live performance engineering (on-stage microphone feedback control), education venues (classrooms, auditoriums, gymnasiums), entertainment venues (KTVs, bars), and religious spaces (churches, temples) requiring reliable acoustic feedback management.
