Harmonai KX2 Professional Karaoke Preamp product image

Product Overview

The Harmonai KX2 is a professional-grade karaoke preamp processor featuring a premium aluminum front panel and an ultra-slim 1U chassis—elegant in appearance and space-efficient for rack mounting. Its standout feature is 6-band parametric equalization for microphones, offering wide adjustment range to refine vocal clarity and smoothness without compromising original tonal character. It enables precise suppression of feedback frequencies. The subwoofer channel output includes adjustable crossover point and output gain, plus comprehensive low-frequency anti-self-oscillation circuitry: when microphone signal is active, the subwoofer output automatically attenuates by 50% to prevent low-frequency howling and protect equipment. A dedicated ‘mic signal exclusion from subwoofer channel’ function, combined with intuitive card-slot-style controls, simplifies setup and fine-tuning.
