Professional audio, microphones and system integration

The Harmonai LEO-310T is a professional-grade UHF wireless microphone system featuring a standard 1U rack-mount chassis, with flexible switching between dual-channel (one transmitter, two receivers) and single-channel (one transmitter, one receiver) modes. Equipped with a phase-locked frequency synthesizer, it ensures clean, stable signal transmission across the 500–900 MHz wideband modulation range, with an effective transmission distance of up to 100 meters. Its professional dynamic microphone capsule delivers a frequency response of 50 Hz–18 kHz and a total signal-to-noise ratio exceeding 100 dB — ideal for reliable audio capture in conferences, live performances, KTV, and other professional environments.
