Product Overview

The Harmonai GQX-3102 is a professional-grade dual 31-band graphic equalizer, engineered with 1/3-octave resolution for ultra-precise frequency adjustment. Its frequency response spans 20Hz to 20kHz with an error of only ±0.25dB; total harmonic distortion (THD) is below 0.01%; and output noise is lower than -92dBu (unweighted), ensuring pristine, high-fidelity signal transmission. The unit features a built-in subsonic filter (18dB/octave, adjustable from 8Hz to 200Hz) to effectively suppress low-frequency noise and feedback howl — making it the ideal choice for professional audio systems, recording studios, live performances, KTV rooms, and all types of sound reinforcement applications.
