HR-31S + H-31

Single Channel Wireless Receiver (HR-31S) with Wireless Handheld Microphone (H-31)

HR-31S true diversity wireless microphone system is a wide bandwidth true diversity wireless audio system that designed for the large-scale live show.Powerful function,reliable performance,can get the best effect in different kinds of complicated professional performance.

Functional Features

• Intelligent Management - The optional "RWW" wireless transmission system monitoring and management software can use computer networking to monitor on-site, search for radio wave interference points in the actual environment of the scene and frequency blind spots on the stage, and control and modify system settings.
• AFS(Automatic Frequency Selection) - With [AFS] automatic search channel function, after pressing the [AFS] key for 3 seconds, it will automatically search and lock on an undisturbed working channel.
• IR Infrared - With [IR] infrared automatic frequency matching function, as long as the [SYNC] button is pressed, the transmitter can automatically and accurately lock the working frequency of the receiver.
• Energy Conservation - Precise low consumption circuit design makes the battery life twice as long as that of ordinary microphones.
• Anti-Interference - The stable PLL phase-locked oscillation circuit, combined with the "noise detection" mute control function, can effectively block the noise and radio frequency interference in the working environment.
• Super Wide Frequency Range - 32MHz broadband design, more than 1280 frequency points can be selected, true diversity reception.
