Product Overview

The Harmonai HK-835 true diversity wireless microphone system employs multi-channel DPLL digital phase-locked loop frequency synthesis technology and automatic noise control, operating in the UHF 640–690 MHz band to effectively avoid interference frequencies. Equipped with a true diversity dual-microphone receiver circuit, paired with high-gain antennas, it achieves a maximum open-space operating distance of up to 100 meters — ensuring stable, dropout-free signal transmission. The intuitive jog-dial interface and VFD color display automatically shift colors during standby, and instantly switch upon signal reception or user interaction, making operational status immediately visible. Supports fully automatic infrared sync, automatic scanning, and fully automatic power-on/off modes for fast, efficient operation.

Its double-conversion RF circuit design delivers exceptional sensitivity; combined with high-frequency surface acoustic wave (SAW) filters, it maximizes out-of-band interference rejection. A unique voice compression/expansion circuit and voice limiter ensure significantly improved SNR and dynamic range (100 dB): even at full vocal output, no distortion or clipping occurs — preserving natural, high-fidelity sound reproduction. Independent and mixed output interfaces allow flexible connection to mixers and Karaoke amplifiers, making it widely suitable for public speaking and Karaoke performance applications.

Recommended Applications

Thanks to its stable signal transmission and outstanding audio fidelity, the HK-835 true diversity wireless microphone system is widely used in professional settings including public speaking, conference hosting, Karaoke (KTV) performances, stage shows, and live event sound reinforcement. Its dual-microphone configuration supports simultaneous use by two people, while true diversity reception maintains uninterrupted signal integrity even in complex electromagnetic environments — making it an ideal choice for professional audio systems and premium KTV venues.
