Product Overview

Harmonai W-6900 True Diversity Wireless Microphone System is a professional-grade UHF dual-channel wireless microphone designed for stage performances, public speaking, and karaoke. It employs DPLL digital phase-locked loop multi-channel frequency synthesis technology and automatic noise control to operate in the dedicated UHF 640–690 MHz band, effectively avoiding common interference frequencies. The system provides 200 selectable channels, with 250 kHz channel spacing and ±0.005% frequency stability — ensuring clean, reliable signal transmission.

The unit uses a true diversity receiver circuit paired with high-gain antennas, delivering up to 100 meters of effective range in ideal conditions — eliminating signal dead zones entirely. Its unique voice compression/expansion circuit extends dynamic range to 100 dB, with an overall signal-to-noise ratio exceeding 105 dB — enabling vocalists to sing at full power without distortion or harsh clipping.

Recommended Applications

The Harmonai W-6900 True Diversity Wireless Microphone System is widely used across professional environments: In stage performances, its dual-mic design supports simultaneous singing and instrumental performance, while true diversity circuitry maintains uninterrupted audio even during wide-stage movement; For public speaking, the dedicated UHF band avoids dense urban RF interference, and the 100-meter transmission range covers large venues; During karaoke performances, voice compression/expansion technology preserves clarity in both high and low registers, and independent/mixed output interfaces simplify connection to various sound systems; In conference rooms and classrooms, automatic infrared sync and jog-dial operation enable fast, intuitive setup.
